Laboratory Remodeling
In 2011, the RWU Maintenance Department personnel completed the laboratory remodeling work. The work
encompassed replacement of the north wall casework and countertop, the center island casework and countertop, new
casework along the east lab wall and the bacteriological lab, rehabilitation of the casework and bench-top of the
chemical storage area, and a new epoxy floor coating throughout the laboratory. The present-day laboratory,
constructed in 1954, had used the original casework from 1930s.

Cracked, Leaking Water Main
Leak Detection
Historically, leak detection was performed sparingly each year, by an outside consultant. After discussions with staff, it
was decided that leak detection could be performed more cost effectively with in-house personnel and would also allow
for a greater portion of the system to be surveyed each year.
The Utility began its own in-house Leak
Detection Program in the spring of 2011, with
the purchase of a digital Leak Surveyor. This
device is an acoustic amplifier, which allows
the user to pick up the sound of even the
slightest leak in the area.
Detecting and locating leaks requires several
steps, the first of which is to check the general
area for any sounds that may indicate a leak.
This is done by connecting the Leak Surveyor
to fire hydrants, which are evenly spaced
every block and easy to connect to. If noise is
heard on a particular hydrant, there is a good
chance of a leak nearby.
The operator then listens to nearby water
services and valves, which are typically
spaced every 40-100 feet, gauging which
location has the loudest noise. The
construction crew may also drill holes and
push steel probes into the ground in order to
provide for additional listening locations if
nearby valves and services prove insufficient.
After several iterations, the source of the leak is found and repairs are made. This method is fairly accurate, though
somewhat time consuming. The Construction Department plans to purchase a Leak Correlator in 2012, which should
help the crew locate leaks more efficiently.
Leak detection was performed intermittently throughout the year, as time permitted. Roughly 15% of the system was
checked for leaks in 2011, resulting in the detection and repair of over 30 leaks. As leaks were exposed, employees
would try to determine the leakage rate via flow gauges, filling of buckets, or by visual estimate.
An estimated 130,000,000 gallons of lost water were saved in 2011 thanks to the new leak detection program. Based on
2011 chemical costs and electric rates, the RWU saved $17,025 from the implementation of the leak detection program.
In 2012, the Construction Department will take the program a step further by purchasing a leak correlator. The
correlator will work hand in hand with the digital Leak Surveyor, and will allow for more precise and efficient leak
detection operations.

Large Meter Testing Program
The year 2011, kept personnel busy monitoring, removing, and replacing meters in the multitude of vacant/abandoned
properties in the service area. Several differences between the inside (base) meter and the outside register (old-style
Read-O-Matic technology) were found and rectified. Meter change records indicate at least 26,460,500 gallons (35,375
ccf) of usage (approximately $82,500 in water revenue) was found to be unread and these meters were all converted to
the Orion reading system.
In 2011, the Meter Department increased its effort, time, and funding to test, repair, and replace large meters
(meters > 3”). Under-reporting large meters, because of the large water volumes, have a significant financial
impact on both the Water and Wastewater Utilities. With new Public Service Commission regulations
addressing ”unaccounted water”, there is now a greater emphasis to lower percentages of this water category
for compliance purposes. Meter personnel tested, changed, and/or serviced 80 large meters in 2011. Several
accounts at large apartment complexes that were deemed problematic had new meters put in. A year-ending
review of these accounts indicates that registered consumption tripled, on average. Also initiated in 2011, was
a program to photo-document large (3” and above) meters in the system as demonstrated in the pictures
below. This record keeping will prove that on the date of inspection, the by-pass line was secure (chained,
locked and tagged by Meter Dept. personnel) and the high and low meter side reads manually recorded since,
for billing purposes, the Orion system only provides a summed read (high and low) total.

Sanitary Pump Discharge Reduction
Part of the lab remodeling project included re-plumbing the lab sampling supply lines. Formerly, the lab sampling
faucets ran continuously with the discharge running to the sanitary sewer system. With the completion of the laboratory
north bench remodeling, the water sample discharge is routed to the retention basin with side-stream sampling to the
sample taps themselves. This configuration as seen in the pictures below insures fresh samples for testing and
eliminates significant amounts of water to the sanitary sewer, thus saving the RWU significant sanitary charges. As
seen from the Graph 1, water to the sanitary sewer system in 2011 was decreased by over 19 million gallons from 2009
and 18 million gallons from 2010. Monetary savings from this modification are included in the total wastewater
services cost reduction.

Time of Day Electrical Use
The Racine Water Utility receives lower electrical rates for each kilowatt it uses during off-peak hours (10:00
PM - 10:00 AM weekdays) compared to on-peak hours (10:00 AM - 10:00 PM weekdays). The kilowatt charge
for peak hours is $0.06646 compared to $0.04732 for off-peak hours. The RWU performs more energy
demanding operations such as high lift pumping, filter backwashing, etc. at night. This mode of operation,
although not new for the Utility, was re-emphasized in 2011. The higher the ratio of off-peak versus on-peak,
the more savings the Utility will incur. As seen in the graph below, beginning in December of 2010 and
continuing in 2011, substantial improvements were made in off-peak energy use.

Staffing Reductions
In 2011, 3 RWU employees retired; the chief engineer and 2 maintenance workers. Through promotions the
chief engineer position was filled by the Civil Engineer II, the Civil Engineer I then filled the vacant Civil
Engineer II and the open Civil Engineer I position was not filled. Only one of the open positions in the
Maintenance department was filled. This staffing arrangement equals a RWU staff reduction of 2 for 2011 and
beyond. These staff cuts equal an approximate annual savings of $150,000 in the Utility‟s operational and
maintenance budget for personnel services based on 2011 wage and benefit rates.

2011 Wastewater Services Summary
Treatment Basins Solids Removal
Introduction
The Racine Water Utility continued to use contractual services in 2011 for its annual solids de-watering
program. Again, the Utility experienced an increase in amount of solids sent for land-filling and a
decrease in amount of solids sent to the wastewater treatment plant. As the Utility becomes more
experienced with this operation, operating and equipment improvements have increased the efficiency of
this program.
Graph 1 shows the estimated residual treatment solids generated by pre-treatment of lake water and stored
in the sedimentation basins. Yearly tonnage varies according to lake water quality, weather conditions,
and amount of chemical used. In this data set, from 2002 through 2007, all solids flowed to the
wastewater treatment plant for treatment and removal. Starting in 2008, the RWU hired Synagro, Inc. to
on-site dewater the settled solids from the sedimentation basins. The contractual price for this service
totaled $240,807 for 2011. If the Utility had not conducted on-site dewatering and instead sent this waste
down to the Wastewater Utility, the cost would have been about $460,044, thus saving the RWU
approximately $219,237 in wastewater charges just for annual basin cleaning. In 2011, the loading of
solids on the wastewater plant decreased to only 4.1 tons. This solids loading reduction to the sanitary
sewer system significantly improves operations and eases solids treatment and handling for the
Wastewater Utility.

2011 Achieved Wastewater Service Savings
The sanitary sewer fee for 2011 was $44,779 compared to $104,517 for 2010, or a decrease of $59,738.
As seen in Graph 2, the total wastewater service fee dropped $42,389 from 2011. The 2011 O&M budget
figure for residuals management was set at $400,000. The RWU came in $114,400 under budget for
2011.

Historical Perspective:
Looking at the annual wastewater service cost from a long- term perspective (Graph 3), the current (2009-
2011) dollar outlays are roughly equal to what the Utility paid in 1994. In 1994, the RWU experienced 2
“boil water notices”. The aftermath of the incidents and resulting plant audits by regulators and
consultants resulted in discontinuation of backwash recycling, and instead diverting backwash water to
the sanitary sewer system. As seen in Graph 3, this resulted in immediate and steep increases in
wastewater charges. Over the years as sanitary treatment fees increased, so did the service cost to the
RWU. Off course, just raw dollars does not tell the whole story. Graph 4 illustrates the cost of
wastewater services as a percentage of the total annual operational and maintenance expenses. With the
re-implemented practice of backwash recycling and the on-site de-watering of treatment sediments since
2008, the Utility reduced the percentage of wastewater service cost back to levels experienced from the
late 1970s through the 1980s, and into the early 1990s before the treatment upsets of 1994. As
background to understand treatment residual (wastewater services) practices see below:
1926 - 1977: All backwash water and accumulated treatment solids flushed back directly to Lake Michigan.
1977 - 1994: All backwash water recycled to head of plant. Treatment solids pumped to wastewater.
1994 - 2008: All backwash water and treatment solids pumped to wastewater.
2008 - Present: All backwash water recycled to head of plant. Treatment solids de-watered on site and hauled
to landfill.
[36]

[37]
Effect on Wastewater:
Graph 5 illustrates the financial affect to the Racine Wastewater Utility because of the cost
reduction efforts at the RWU. Revenues from Water Utility operations for the Wastewater
Utility peaked at over 1 million dollars in 2007. In four years, those revenues dropped to just
under $45,000 in 2011.
Graph 5
As seen in Table 1 on the next page, the RWU achieved substantial reduction in wastewater service costs
due to the operational changes described earlier. When one uses the more conservative 3-year average,
the Utility still decreased wastewater service costs by about $683,000 in 2011. As described earlier, 3
operational changes implemented since 2008 account for the majority of monetary savings.
1. 2008: The RWU ceased pumping backwash water to wastewater and began recycling the
backwash water.
2. 2008: The RWU ceased sending treatment basin solids to wastewater, dewatered the solids
and disposed of these solids in a landfill.
3. 2010: In December, the RWU re-plumbed its laboratory sample lines to the retention basin
and eliminated this constant flow (19 million gallons per year) to wastewater.
These achieved savings will continue into the future and may be enhanced as the Utility staff improve
dewatering practices and possibly lower other sanitary discharge volumes.

2011 Electrical Service Summary
Introduction
Electricity remains an essential element for water treatment and conveyance. Potable water production,
on any scale, is impossible without it. Electrical use represents one of the largest costs in a water utility
budget. Over the last several years, the Water Department incorporated a number of measures to reduce
operational electrical demand and procured special contracts with WE Energies to conserve on electrical
usage and control costs. In 2011, the Utility continued programs to save additional monies by improving
operational efficiency.
With the expansion of treatment practices and buildings at the Hubbard Street campus (2003-2005), the
construction of two additional booster pump stations (2004 & 2006), and the acquisition of the Sturtevant
Water Utility in 2007, electrical use and costs rose in these years. In 2011, the Utility experienced an
overall increase in electrical costs and consumption compared to 2010. Table 1 shows the monthly
electrical bills for the Utility for the Hubbard Street facilities and Table 2 the costs for all the remote sites
for 2011.

In 2011, the RWU used over 9.120 million kilowatts to treat and supply water to the distribution system.
Electrical costs for the treatment plant and the distribution system totaled $807,116 while the Utility
budgeted $890,000 for electricity in 2011. Compared to 2010, the RWU saw a usage increase of 96,867
kW. These kW increases can be attributed to higher production due to more water demand in 2011. The
RWU paid $99,897 more for electricity in 2011 compared to 2010. Although higher kW usage caused
part of this dollar increase, WE Energies ended its Point Beach credit, causing an increase of
approximately $85,000 to the RWU.
In order to compare the efficiency of operations with regard to electrical use, the amount (kW) of
electricity used in a time period is divided by the total amount of water produced and pumped out of the
treatment plant. The kW/MG value can then be compared from month to month and year to year. Graph
1 represents the annual average for kW/MG of 1343.9 in 2011. Graph 1 illustrates that 2011 and 2010
used about the same amount of electricity per million gallons of water produced.

Without a doubt, the single most significant cost savings to the RWU for its electrical usage is the
contract for interruptible power with WE Energies. This contract reduced the cost of kilowatts to the
Utility both for on-peak and off-peak usage along with the halving of the monthly demand charge. Since
initiation of this contract in May of 2005 through December of 2011, the Utility saved over $879,500.

2011 Natural Gas Summary
Introduction
Natural gas costs represent another significant portion of the RWU operation and maintenance budget. At
the Utility, natural gas is used for running the boilers for building heat, heating water for domestic use,
and for drying air used in three dehumidification systems in the treatment plant and membrane filtration
building. As the Utility grew in number of buildings, the use of natural gas increased.
In 2011, the RWU budget contained a line item amount of $210,000 for natural gas. Actual 2011 costs
totaled $148,560.45 for all the facilities at the Hubbard Street complex and all the remote sites (booster
pump stations, elevated tank buildings, garage). Table 1 summarizes the monthly bills for all the remote
sites, Treatment Plant, Service Building, Membrane Plant, and Generator Building using natural gas for
heating.

Table 2 and Graph 1 show the amount of therms used each
month in 2011 and the monthly costs for the main building
(filter plant and pump station). Significant reductions in gas
usage annually begin in May and continue into October. As
standard operating procedure, the Maintenance personnel turn
off the boilers in the Treatment Plant and Service Building to
conserve energy use since heating is usually not required
during the late spring, summer, and early fall. The Utility
still uses natural gas in the warm months to operate
dehumidification systems to produce dry air which keeps
corrosion of pipes and equipment down to a minimum during
the higher humidity months. The pattern of gas costs seen in
Graph 1 obviously repeats itself at all the other facilities
using natural gas heat according to seasons.
[42]
Graph 1
Graph 2 shows the annual combined natural gas usage since 1998 for the treatment plant and pump
station. Natural gas usage declined significantly after 2003. In 2004, the Utility installed new
dehumidification equipment and initiated the standard operating procedure of decommissioning the
boilers in the warm weather months. This accounts for most of the therm reduction seen in the last seven
years.
Graph 2
Graph 3 shows, even with generally declining natural gas usage, the annual cost for heating and drying
the two buildings continued to rise due to increased natural gas prices. In 2011, the RWU used about the
same amount of natural gas compared to 2010 but paid significantly less due to lower per therm costs.
[43]
Graph 3
In order to account for the affects on climate conditions on natural gas consumption when comparing one
year to the next, the RWU now uses data supplied by WE Energies detailing the total number of heating
degree days for each billing period since 1998. By dividing the yearly therms used by the total heating
degree days (HDD), the Utility developed a comparative unit of measurement: therms/HDD. Graph 4
shows the annual therms per HDD from 1998-2011, and also plots the changes in efficiency the Utility
achieved from one year to the next. Graph 4 illustrates 2004 and 2005 have the largest increases in
efficiencies due to the boilers being turned off during the warm weather months. In 2009, the Utility
improved the efficiency of boiler operations another 7.3% due to the installation of the new gas burner
with VFD controls and less use of the larger 300 horsepower boiler. In 2010, the efficiency unexpectedly
decreased. 2011 saw the Utility‟s efficiency return to a positive value and therms/HDD value again lower
to 17.1.

2011 Filter Backwashing Optimization
Introduction
The RWU employs poly-aluminum chloride for water clarification treatment. Since the onset of this
chemical treatment in February 2008, the RWU optimized operations in different facets to reduce costs.
The chemical change allowed the Utility to increase conventional filter efficiency and obtain a major
operation benefits and cost significant reductions. This section details the results of filter operations.
A. Length of Run (LOR)
Graph 1 shows the annual average LOR for the past 7 years. In 2011, the RWU maintained a

B. Filter Backwash Number
In 2011, the number of filter backwashes totaled 625, relatively the same as the 2 previous years and
over a 50% reduction in backwash number from 2007 and before. The backwash trend-line
basically follows the historical decline in water production with the past four years‟ larger decrease
due to the coagulant change. Graph 2

C. Backwash Volume
As the number of backwash decreases, so does the overall volume of water used for backwashing.
The volume of backwash water in 2011 was 74.130 million gallons. This represents a decrease of
70.91 million gallons (from 2007) or nearly 4.0 days of finished water production. Based on the
current electrical and chemical costs, the RWU reduced operational costs by $8,945 in 2011 due to
backwash decreases resulting from modified chemical treatment. All other fixed costs (personnel,
building, etc.) are not reduced.

2011 Membrane Optimization Efforts
Introduction
The desire to improve membrane filter operations provided the impetus to change coagulant chemicals
(ferric sulfate to poly-aluminum chloride) in 2008. The purpose was to reduce or eliminate iron carryover
from the conventional treatment plant to the membrane plant, thus to reduce fouling on the membrane
fibers. Reducing fouling rates would theoretically reduce trans-membrane pressure, lower permeate
pump speeds (= lower electricity use), and decrease the need to chemically clean the membrane fibers.
As explained in other areas of this annual report, the chemical change proved beneficial in treatment
practices and cost reduction. It has been no different regarding membrane plant operations. After the
change in coagulant was made, permeabilities increased, showing the reduction in fouling. Graph 1
presents permeability results as an average. The results become obvious of the positive affect of poly-
aluminum chloride on the reductions of fouling rates.

With improvements in permeability (= lower trans-membrane pressure and lower fouling rates), the
frequency for performing chemical clean-in-place (CIP) procedures also declined. As seen in Graph 3,
the 2011 CIPs declined to a total of 31 from 42 in 2010 and more from previous years. Looking at the
actual CIP clean interval over the course of membrane operations, the chemical cleaning interval
increased to 90 days (using the PACl coagulant) from 39 days (using the ferric sulfate coagulant). The
RWU spent over $5,300 less on membrane chemicals in 2011 from 2009 based on reduced chemical
cleaning frequency.

As mentioned previously, the coagulant change resulted in lower fouling rates and lower operating trans-
membrane pressure. With a lowered operating pressure, the permeate pumps run at lower speeds, thus
using less electricity. This electrical reduction and any other electrical savings in the operation of the
membrane plant are captured in the lower kilowatts/million gallon calculations as delineated in the
electrical service summary report.

Graphs 3 and 4 take totalized raw and finished water flows from 1997 through 2011 and present the data as
daily average flow. Water production generally decreased over the last fourteen years. Again, the Utility
distribution system grew and service connections increased, but water production declined, mostly due to lost
industrial customers. Average daily raw water and finished water production in 2011 increased from the
previous year, rising near 0.4 to 0.5 million gallons per day respectively from 2010. Most of the average day
production increase is attributable to the warmer and drier months of July, August, and September of 2011.

The previous graphs indicate that not all water pumped from Lake Michigan goes into the distribution
system. Part of the treated water is needed to run equipment and used for filter backwashing. Graph 5
exhibits the average daily volumes of water needed just for conventional filter backwashing. In 2011, the
average daily backwash water increased slightly to 203,000 gallons/day. The coagulant change from
ferric sulfate to poly-aluminum chloride resulted in increased length of filter runs and lowered the number
of backwashes accounting for the reduced volumes compared to 2008 and before.
Graph 5
Table 3 presents the historical maximum and minimum day finished water flows to the distribution
system since 1985. Recorded daily high flows for each year are highly dependent on weather conditions.
In 1988, the RWU set its all-time daily maximum flow. That year, the area experienced extreme drought
conditions. In 2010, the lowest minimum day production occurred for over the last quarter century. Table 3

Wholesale Customer Water Demand and Revenue Graph 1 shows the historical trends of totalized water usage by the wholesale customers. Like water
production figures, wholesale use follows the same declining trends over the last decade.
Graph 1
As seen in Graph 2, the actual revenues to the RWU from the wholesale customers generally increased
historically. This increasing trend is mostly likely influenced most by rate increases. Both graphs show a
steep decline in 2007 as a result of the Village of Sturtevant changing from a wholesale to a retail
customer. With the rate increase in 2011, and an increase in sales of purchased water, wholesale revenues
rose in 2011 from 2010.

[54]
Residential Trend in Water Consumption
The RWU compiles many statistics for the Wisconsin Public Service Commission on an annual basis.
The Great Lakes Compact stresses and urges water efficiency and conservation in the State of Wisconsin
to preserve the valuable resource of water that we have at our door step in Racine. The State has
appointed a Water Conservation position to oversee and monitor water conservation efforts in Wisconsin.
Recently, environmental groups have intervened in water rate cases in Waukesha, Wisconsin to strongly
encourage conservation efforts among residential customer classes. Incentives for water conservation
have been to enact inclining block water rates to discourage more than the average use by residential
customer classes.
The City of Racine is a good example of trends in residential consumption considering that the
community is fully developed and it is rare for new home starts. The information presented in the Graph
1 indicates that water consumption in the residential class in Racine, Wisconsin has dropped from 2002 to
2010 by 20.1%. This drop can be explained by many factors; an aging population where the number of
individuals per household may have dropped, rate increases in recent years have caused residents to
conserve in order to keep water bills at a tolerable level, installation of water saving toilets and shower
heads, reduction in lawn watering with increasing water rates and wetter periods of climate, economic
downturn that may be increasing the number of vacant properties or empty dwellings. The bottom line is
that the Utility has seen a decline in residential consumption. In 2011, the RWU experienced a small
increase in residential water usage reversing a 5-year trend of declines.
Graph 1
It would be onerous on residential ratepayers to further reduce their consumption by imposing inclining
block rates to further provide a disincentive to use water on a local level. Lake Michigan serves as
tremendous source water that has not deviated in level by more than a few feet in over 100 years of
record. The resource is currently plentiful and Racine is not in the same situation as a community that
might be using groundwater as a source of its water.
[55]
Racine Water Utility Rates
1992 – 2011
Over the course of the past 19 years, the consumer‟s cost of water rose from $0.61 to $2.12/100ccf. This
parallels inflation over the same time period and reflects the true cost of water and improvements
undertaken at the Utility to improve supply, treatment, and water quality. Graph 1 shows the actual cost
of water to a residential user based on 100 cubic feet (748 gallons) of water purchased.
Graph 1
Graph 2 shows the actual Wisconsin Public Service Commission (PSC) approved rate increases since
1992. The PSC granted the RWU an overall 15% rate increase in 2011. Concurrent with the higher
operational and capital expenditures, the RWU, like almost all area water utilities, experienced declining
water sales. This reduction in sales and revenues puts further pressure to raise rates.

Water Treatment Chemical Costs
Chemical costs are a significant portion of the annual operation and maintenance budget. Annual costs
for chemical treatment are influenced by the amount of water production, quality of source water, and
market variables. Figure 1 shows the 2011 chemical costs.
Figure 1
The Utility uses six different chemicals for the direct production of water. For membrane cleaning and
neutralization, four chemicals are used. Graph 1 depicts the steeper incline in chemical costs from 2006
through 2009. Some of this is due to the inclusion of the membrane cleaning chemicals, but most is
attributed to the higher costs of chemicals. For the second year in a row, annual chemical expenditures
declined. In 2011, the Utility spent $381,717 on treatment chemicals ($51,983 less than 2010). The cost
reduction is due to stabilization of market forces and a 30% reduction in fluoride use to meet new EPA
and HHS guidelines.

2011 Water Treatment Chemical Use
[60]
Recent Historical Water Treatment Chemical Use
The RWU employs six chemicals to produce potable water to meet all Federal and State guidelines for
water quality. Without chemical addition, micro-organisms may survive in, particles would pass through
to, and taste and odors would exist in the finished product the Utility‟s customers would consume. The
following figures summarize chemical usage since 2002.
Chlorine Chlorine is a strong oxidizer used
to disinfect the source water to
produce water free of viruses,
bacteria, and protozoa. Chlorine
dosages remained relatively steady
with the total pounds fed
decreasing over time due to
lowered water production. Total
chlorine use increased in 2011 due
to higher water production.
Chlorine treatment remains the
single most important chemical
process in use at RWU.
Coagulant A coagulant clarifies the water by
producing a small precipitate
which settles to the bottom of a
tank. Since 2000, the RWU
employed either ferric sulfate or
poly-aluminum chloride. Total
pounds fed have essentially
remained the same over this time
span.
Potassium Permanganate Potassium permanganate, another
strong oxidizer, serves numerous
purposes at the RWU. The Utility
first used this chemical in 1967 for
taste and odor control. In 1995,
chemical addition was moved to
the intake cones for zebra (&
quagga) mussel control.
Permanganate gives the Utility an
early warning of water quality
changes in the Lake. Dosages have
remained relatively constant the
past three years.
[61]
Cationic Polymer Cationic polymer (or coagulant aid
polymer) enhances the clarification
of the source water. This chemical
contains positive charges along the
length of the molecule which
attract the negatively charged
colloidal material found in Lake
Michigan water. This chemical‟s
use has decreased historically due
to better mixing, lowered water
production, and optimization of
pretreatment operations.
Hydrofluorosilicic Acid (Fluoride)
The RWU feeds fluoride to be
incorporated into the tooth enamel
and bone structure of children and
adolescents. The feed rate was
dropped in 2011 to maintain a
fluoride dosage of 0.7 parts per
million (optimum concentration to
prevent dental caries). Total
annual pounds fed vary with the
amount of water produced.
Lower water production equates to
less chemical consumed.
Blended Phosphates
Since 1993, the RWU has fed a
phosphate to the finished water in
decrease corrosion of metal pipes
in the distribution system and the
customers plumbing. The main
purpose is to lower lead and copper
concentration in the customers‟
“first draw” water. In 2004, the
Utility exceeded the lead maximum
contaminant level. Increases in
amount of phosphate fed since
2004 are due to the Utility‟s efforts
to regain and maintain compliance
with the Lead & Copper Rule.

Racine Water Utility
2011 Finished Water Quality Report
Introduction
People using Lake Michigan as their source water are fortunate to have such a plentiful and high quality
supply. A properly operated and maintained treatment plant produces drinking water which is completely
safe and pleasing to the drink. State and federal regulations require the RWU and all water utilities, to
monitor the treatment plant finished and distribution waters. This monitoring ensures the highest possible
quality and protects the public's health. Many different parameters are tested at various frequencies. The
attached water quality analysis lists all the chemical, microbiological, radiological, and physical tests
performed, their results, and the maximum contaminant levels (MCL) allowed for each. Frequency of
testing depends on each particular parameter and their chance of occurrence and historical levels found.
Typically, MCLs have not been established for some parameters due to incomplete research, unknown
occurrence data, or no known adverse effects. The Water Quality Analysis is divided into seven sections.
The first five deal with the required monitoring parameters and the last two for general information. The
Utility produces finished water meeting all state and federal regulations.
Inorganic Chemicals
The inorganic chemical section is subdivided into the primary, secondary, and unregulated chemicals.
MCLs for the primary regulated chemicals are based on the possible adverse health effects. MCLs for the
secondary regulated chemicals are based on the possible aesthetic influences on water quality. “Less
than” signs before numerical results indicate the contaminant is absent or the concentration is below the
analytical detection limit.
Turbidity
Turbidity is a measure of water clarity and a very important monitoring parameter. Strict internal
standards are set. Turbidity measures the effectiveness of total treatment plant performance. Low
turbidity indicates optimized chemical treatment and filtration. High turbidity is aesthetically
unappealing and allows pathogens to possibly escape the disinfection process.
Organic Chemicals
Regulations established maximum contaminant levels for organic chemical based on their carcinogenic
effects in laboratory animal studies, with the results extrapolated to human exposure. This section is
subdivided into volatile organic chemicals (VOC), synthetic organic chemicals (SOC), and disinfection
by-products (DBP). VOCs and SOCs found in the water result from pollution in the watershed. DBPs
result from naturally occurring organics reacting with chlorine used for disinfection. “Less than” signs
before numerical results indicate the contaminant is absent or the concentration is below the analytical
detection limit.
Radioactivity
In general, Lake Michigan contains very low levels or no radioactive isotopes. There is either no risk or
extremely little risk from radioactivity using surface water.
Microbiological Parameters
The most important process at any water treatment facility is disinfection. To ensure the water is
pathogen free, bacteriological tests are run daily on plant process and distribution waters. Treatment
techniques require specified minimum levels of treatment to remove or inactivate protozoa, bacteria, and
viruses from the water.
The last two sections are for general information and are self-explanatory. At the end of the report is a
list of definitions footnoted in the text of the report.
In summary, the RWU‟s finished water is of excellent quality, meeting all state and federal limitations
and regulations.

Racine Waterworks Recent Historical Water Quality
Introduction
All public water systems must meet minimum Federal and State quality requirements for producing
potable water. The Utility tests for numerous parameters to gauge the water quality, the effectiveness of
treatment, and to ensure public health. The frequency of testing of these parameters depends on past
occurrence and the importance to public health.
Turbidity
Turbidity is the measurement of the water clarity. It is important from two standpoints. First, from an
aesthetic standpoint, crystal clear water is more desirable and palatable to the consumer. Second, and
more importantly, particles left in the water may provide hiding places for pathogens to escape
disinfection. So, the goal of any water producer is to provide water with the lowest turbidity possible.
Governmental maximum contaminant levels require the finished water discharged from the treatment
plant to be less than 0.30 NTU 95% of the time and never to exceed 0.50 NTU. Graph 1 shows the
historical peak finished water turbidity from 1997 through 2011. The slight finished water turbidity
increases in 2008 – 2009 are due to the use of different turbidimeters measuring the plant discharge. The
dramatic lowering of finished water turbidity after 2005 is due to the addition of membrane filtration to
the treatment process.
Graph 1
Disinfection
Disinfection of water remains the most important treatment process of any water supplier and is probably
the most important practice undertaken by society to protect public health. In underdeveloped regions of
the world, waterborne disease remains the number one killer of humans, even today. Graph 2 displays the
historical free chlorine residual in the finished water leaving the treatment plant. For many years, the
RWU set free chlorine residual goal at 1.0 parts per million. As seen in Graph 2, for most years, the
Utility successfully maintained the 1.0 ppm goal. In 1997-1998, and again in 2004, the average finished
water chlorine residual was significantly higher. In these years, RWU staff operated with higher chlorine
residual to meet disinfection regulations. In 1997 and 1998, the Utility constructed baffle walls in the east
reservoir in order to bring the Utility in compliance with the Surface Water Treatment Rule to provide the
proper contact time for disinfection. With the east reservoir out of service and new piping between the
filter plant and high lift pump station under construction, the plant needed a higher disinfection level to
maintain the proper CT value due to the decreased contact time. In 2004, the Utility again ran with a
higher residual goal for a couple of months because of the removal of the east reservoir from service for
[71]
construction of pipeline to tie in the membrane filtration plant into the water treatment scheme. From
2005-2011, the RWU again returned to the 1.0 ppm goal, with the average residual in 2011 at 1.07 ppm.
Graph 2
Water Stability
Alkalinity and pH measurement of the drinking water tell much about the effects of water treatment on
the source water and the aggressiveness of the water on plumbing and fixtures. Generally, higher pH and
alkalinity make the water less corrosive to metal piping. As seen in Graph 3, from 1997 through 2007,
the pH of the finished water sat around 7.4 standard units. In 2008, the average finished pH increased to
7.65, 7.72 in 2009, and 7.69 in 2010-11. Finished alkalinity since 1997 decreased through 2005 and
stabilized through 2007. After 2007, the alkalinity concentration (parts per million) increased to 107
(2008), and 106 (2009-2011). Both the pH and alkalinity increase were caused by the switch to poly-
aluminum chloride as the Utility‟s coagulant. This chemical, when dosed to the source water, lowers the
pH less and depletes the alkalinity less than the iron salt coagulants the RWU previously used. This
significant improvement in water quality makes the water less corrosive and provides a better foundation
for building a protective film on pipe interiors.

Corrosion Control
The Lead and Copper Rule promulgated in 1986 required water purveyors serving over 50,000 people to
conduct corrosion control treatment. In 1993, the RWU began feeding ortho-poly phosphate blend to the
finished water as it left the treatment plant for corrosion control. Ortho-phosphate, over time, creates a
thin protective barrier on the inside of water pipes. This barrier ideally prevents direct contact between
the water and the metal pipe. Thus, the metal atoms cannot dissolve into the customer‟s water. Graph 5
shows the ortho-phosphate concentration in the finished water since 1997. From 1997 through 2005, the
Utility maintained an ortho-phosphate concentration of 0.25 ppm. In 2004, the Utility exceeded the
maximum contaminant level for lead.
In 2006, the Utility changed chemical suppliers and the blend of phosphate. For 2006-2007, the ortho-
phosphate residual target became 0.40 ppm. Beginning in late January 2009, the RWU increased ortho-
phosphate concentrations in the drinking water to a target of 0.70 parts per million (ppm) as it strives to
lower corrosion rates and reduce lead and copper concentrations in the consumer‟s water.

[73]
Fluoridation
Fluoridation, practiced by the RWU since 1950, helps protect the population from dental caries (cavities).
When the fluoride level in drinking water is maintained at a concentration of 1.0 to 1.1 ppm, cavities are
reduced approximately 67% as shown by numerous epidemiological studies. Fluoridation, although not
required under Wisconsin State Statutes, is recommended by the American Water Works Association, the
American Dental Association, American Medical Association, and other public health agencies as a
practical and economical way to improve public health. In early 2011, the Center of Disease Control and
Department of Health and Social Services recommended a lower optimum dose for drinking water
fluoride to be 0.70 ppm. Although not mandated, the RWU voluntarily complied with this new guideline.
Graph 6 shows the Utility‟s historical success at maintaining the fluoride residual at optimum levels.

2011 Report on “First Draw” Water Quality
Lead Data
Graphs 1-3 summarize the lead concentrations in the first draw samples from the approved lead and
copper sample sites. In 2004, the RWU exceeded the 90th percentile 15 ppb lead level. The Utility
received a sampling waiver from the Wisconsin Department of Natural Resources (WDNR) for 2005.
The next two years, the Utility continued to exceed the 90% lead standard to various degrees. In 2008,
the RWU changed its coagulant chemical from ferric sulfate to poly aluminum chloride. This change
resulted in a higher finished water pH, higher alkalinity, and lower iron concentrations. These subtle
changes in the finished water quality made the water less aggressive and may have provided the necessary
impetus for the protective corrosion inhibitor film to become stronger and more uniform, thus reducing
corrosion enough to bring the Utility back into compliance with the Lead and Copper Rule. In late
January 2009, the RWU changed the formulation of its corrosion inhibitor to a 70/30 percent ortho to
polyphosphate blend. Sampling in 2011 produced a 90% lead level of 7.5 parts per billion. For the past 3
years, the Utility has maintained very low 90% lead levels.
Graph 1
Graph 2 shows the average lead concentration of all the samples. The average value in 2011 increased due
to 2 out of 52 samples having high lead levels.
Graph 2
[75]
Graph 3 shows the median lead concentration, meaning half of the samples have lead values higher and
half of the samples have lower values. This data analysis shows a significant improvement in 2008 and a
continuing decline through 2011. Again, results from 2011 were based on 52 samples.
Graph 3
Copper Data
Graphs 4-6 summarize the copper results. Since the Utility has never exceeded the copper maximum
contaminant level, there has been less tracking of historical data. These graphs all show an improvement
in copper concentrations since 2006 and stabilization of copper corrosion through 2010. In 2011 the
RWU incurred further decreases in 90%, average, and median values.
Graph 4
[76]
Graph 5
Graph 6
Summary
The RWU returned to compliance with the Lead and Copper Rule in 2008 with two consecutive sampling
periods below the 90% lead level of 15 ppb. Low lead 90% values continued through 2011. Under the
WDNR Draft Consent Order issued in early 2008, the RWU would have begun mandatory lead service
line replacement in 2009 at an annual rate of 7% costing the Utility approximately six million dollars per
year. Concurrent with the lower lead levels, the copper concentrations decreased, confirming the
interpretation the RWU improved its finished water quality and reduced corrosion rates.

Professional, Technical, and Safety Training
In today‟s highly technological, regulated, and legally influenced environment, continuing education and
training remains an extremely important component for conducting business. All employees of the
Racine Water Utility participate in numerous mandatory safety training programs and diversity seminars.
Supervisors are strongly encouraged to participate in City-sponsored supervisory training to improve their
management skills and extend their knowledge of labor laws. Forty-three RWU employees possess either
or both of the Wisconsin Department of Natural Resources Surface Water and Distribution Operators
licenses. Possessing a WDNR certified operator‟s license requires 18 hours of continuing education
credits every 3 years.
Supervisory and Administrative Sessions:
The Cities, Villages, and Municipal Insurance Corporation (CVMIC), one of the City of Racine‟s
insurance carriers, provides numerous types of safety and administrative training seminars at no cost to
their clients. The RWU utilized many of these training opportunities in 2011. Table 1 summarizes the
administrative training from CVMIC received by Utility personnel this past year:

Technical & Professional Sessions:
Professional and technical training comprises another large portion of continuing education time.
Maintaining staff certification with the WDNR, keeping abreast of evolving technology, and knowledge
of new State and Federal regulations, remain an essential part of Utility Staff‟s training regimen. The
RWU uses professional organization such as the American Water Works Association, Wisconsin Water
Association, the West Shore Water Producers Association, etc., and vocational schools‟ resources in
meeting the continuing education requirements. Most sessions presented by these organizations are fee
based and the Utility budgets money each year for attendance to these seminars. Utility suppliers
(chemical and equipment) provide another source of education. Alexander Chemical gives annual
training to Utility operators and maintenance staff dealing with the technical and safety aspects for correct
chlorine gas application. Equipment suppliers periodically provide training on pumps, electrical
switchgear, etc. Fortunately, these valuable resources most often come at no cost to the RWU. Table 2
summarizes the professional and technical training taken in 2011:

Safety Programs and Training:
One goal of any employer is to provide safe work conditions for its employees. Safe work conditions
include proper design and maintenance of facilities, use of approved equipment, and proper use of
personal protective equipment. Safety training forms the foundation to protect the Utility workers,
describing practices workers can and must take for self-protection. The safety policies and associated
training are required under State (Wisconsin Department of Commerce) and Federal (Occupational Safety

Summing all the training hours which occurred in 2011, the total amount of training hours for the Racine
Water Utility personnel was 1,046 hours.
Another facet of workplace safety is a safety committee. A very active safety committee exists at the
Racine Water Utility. The RWU Safety Committee meets on a monthly basis (3rd
Tuesday). The
Committee is made up of management and union personnel from Engineering, Laboratory, Meter,
Construction, Operations, and Maintenance Departments. The Administration is represented by the
Racine Water and Wastewater Utilities Chief of Operations. The Safety Committee performs many
functions. It reviews and amends all the above mentioned safety program policies. Annually, it conducts
safety inspections of the Hubbard Street facilities, the 7 elevated storage tanks‟ buildings and grounds,
and the 4 booster pump stations. The Safety Committee encourages, accepts, and reviews safety
suggestions from all employees. The Committee recommends remedial actions to address the safety
suggestion or refers to management with recommendations if monetary outlays are required. The
Committee reviews all reportable accidents, assesses the cause, and may provide procedures and actions
to prevent similar future accidents.
Reportable and Lost Time Accidents
As required by the RWU insurance carrier, due to worker compensation laws, the Utility maintains
records on all reportable accidents in the workplace. The RWU policy requires that employees report to
their supervisors any accident causing bodily injury, no matter the severity. These records are kept in the
confidential medical files and reported to CVMIC. Lower injury rates and decreased loss time due to
[81]
injuries suffered in the workplace lowers the insurance premium paid by the Utility. The list below
summarizes all the reported workplace accidents which occurred in 2011.
Construction Department February 4, 2011 Worker did not report to any health care facility for treatment (shoulder strain)
October 5, 2011 Worker did not report to any health care facility for treatment (shoulder pain)

Operations Department
The Operations Department consists of 11 individuals whose duties can be divided into three distinct
sections of job responsibilities:
Operations: Consists of Operations Supervisor and 7 Treatment Plant/Pump Station Operators
Technology: Consists of Technology Supervisor
Laboratory: Consists of a Water Resource Chemist and Laboratory Technologist
Operations
This section is responsible for all chemical water treatment, water filtration, raw and finished water
pumping, booster station pumping operations, and elevated water storage control. Treatment plant
operators perform routine laboratory tests daily to monitor water quality and provide information to make
chemical dosage decisions. Other significant duties include performing membrane fiber repair, 1,957 in
2011 and generator testing, 12 test runs for 31.75 hours in 2011. Operators are responsible for receiving
and proper off-loading all chemical deliveries. Operators also perform custodial duties and small
maintenance procedures. An operator is on duty for work 24 hours a day, every day of the year.
Technology
This section oversees, modifies, and upgrades the software to run the Supervisor Control and Data
Acquisition system (SCADA), which Operations uses to monitor and alter plant performance, including
all programmable logic controllers. Other job functions include overseeing the radio communications
system, the security surveillance system, historical data servers, email systems, and attending to personal
computer issues. The Wastewater Utility also shares in available labor hours with this position.
Laboratory
The RWU Laboratory and its two fulltime employees perform daily routine monitoring of lake, process,
finished, and distribution waters. Additionally, water plant operators perform scheduled daily tests. The
Utility Laboratory serves four primary purposes: 1) analyzing the water to ensure the water is free of
harmful pathogens, 2) monitoring water quality to ensure compliance with all federal and state water
quality regulations, 3) testing of certain parameters to supply an aesthetically pleasing product, and 4)
monitoring all treatment processes to produce peak operating efficiency.
Laboratory Testing
Graph 1 categorizes the microbiological (bacteria, Cryptosporidium, Giardia, virus) sampling completed
in 2010. Staff took a total of 4,642 bacteriological samples and the laboratory personnel performed over
10,200 bacteriological analyses. Graph 1
[84]
Graph 2 delineates the number of chemical and physical tests performed by laboratory staff, operators,
and meter inspectors. These individuals conducted over 36,300 separate chemical and physical tests in
2010.
Graph 2
- Chlorine testing includes treatment plant, routine distribution, construction, and special samples
- Majority of turbidity results from plant sampling
- Organic testing includes the following parameters: total organic carbon, halo-acetic acids, tri-
methanes, UV254, UCMR2, and tannic acids
- Inorganic testing includes the following parameters: pH, alkalinity, potassium permanganate residual,
iron, ortho-phosphate, aluminum, fluoride, sodium, nitrate/nitrite, lead, and copper
[85]
Maintenance Department
The RWU staffs 12 fulltime positions. This department includes the Maintenance Supervisor, Electrician,
Lead Person, Stockroom Clerk, and 8 Maintenance Workers. This department performs, or is responsible
for, all work activities involving repair, upkeep, and preventative maintenance of buildings and
equipment. Additionally, the supervisor of this department coordinates and manages most work
performed at the RWU facilities by contractors, vendors, and service people. This department also
maintains all facilities‟ grounds such as grass mowing, shrub trimming, and snow removal. Facilities
include the main campus at Hubbard Street (Pump Station, Filter Plant, Service Building, Generator
Station, and Membrane Filter Building), 4 booster pump stations (Perry Ave., Newman Rd., Hwy. 20, and
Rayne Rd.), 6 elevated storage tanks (Summit Ave., Coolidge Ave., Regency Mall, Perry Ave., Newman
Rd., Renaissance, and Broadway), pipe storage yard at the Regency Mall tank grounds, and a storage
garage on Michigan Avenue in Sturtevant.

[87]
Meter Department
The Meter Department employs 11 people; the Meter Supervisor, Clerk/Dispatcher, Meter Readers (2),
Inspectors (4), and Meter Repair-workers (3). The Meter Department hired one employee in March 2011
as a meter repair-worker to fill an open position due to retirement. This Department‟s responsibilities
include reading all meters in the retail system, reading meters measuring water sold to the wholesale
users, changing meters as per Wisconsin PSC rules, testing meters for accuracy, taking water quality
samples in the distribution system, tapping water mains for new service connections, handling incoming
phone calls, conducting locates of RWU underground facilities and responding to customer complaints.
In 2011, with the assistance of a private contractor, the Meter Department implemented the Utility cross-
connection control inspection. This program expanded the duties of this department significantly due to
the time needed for inspections, public education, and verification of corrective measures.
At the end of 2011, the distribution system consisted of 34,193 services with 34,502 meters ranging in
size from 5/8” to 12” in diameter measuring volumes used by the Utility customers. The responsibility of
reading the vast majority of these meters falls to the Meter Readers, who, on a quarterly basis, walk or
drive the various routes, either manually or electronically recording the customers‟ water usage.
Industrial meters are read and invoiced monthly in the same manner.
The Meter Inspectors take water distribution samples, perform water service taps, conduct inspections,
connect new customers, and provide customer service by answering questions and troubleshooting
problems that the customer may have with their water usage or water quality issue.
The bulk of meter changes fall onto the Meter Repair-workers. Meters need to be changed periodically
per requirements of the PSC. Large meter tests must also be conducted, some annually, and most meters
returned to the shop after removal are also tested in-house. The Meter Repair-workers also track
inventory of meter supplies in the stockroom and accommodate bulk water trucks that come to the plant
to be filled.
The Clerk/Dispatcher answers/routes phone calls, schedules appointments, and greets visitors who come
to the plant. This position is also responsible for the extensive record-keeping of meter department data.
In recent years, the RWU implemented use of automated meter reading (AMR) technology to supplement
the manual reads taken by the Meter Department. The RWU employs two versions of AMR, telephone
reading (Access PlusTM
) and radio reading (OrionTM
). These systems dramatically decrease time needed
to read residential areas and industrial/commercial customers. Using the Access Plus system, water
meters located in high water use facilities “call” in the meter readings to the Annex offices over phone
lines every month to bill the industrial customers. The monthly bill improves the Utility‟s cash flow and
provides real time information to the Utility‟s industrial customers on their water use. Over 36% of meter
reads are done through an automated process. At the end of 2011, the RWU decreased its number of
Access Plus meters from 83 (2010) to 48, or a decrease of 35 meters. These meters were replaced with
the Orion system making reading easier and more standardized. By the end of 2011, the RWU employed
approximately 14,363 Orion meters in its distribution system. As a matter of policy and municipal codes,
the RWU now installs Orion type meters on all new customers services and replaces existing meters when
meter change-outs are scheduled. The use of this latest technology makes meter reading more efficient
and more accurate.

Looking at the above work summary, 2011 showed changes in the amount of work performed in certain
categories from the previous years:
Residential meter change-out and testing increased, due to the hiring of a meter repair worker for a
position which had gone unfilled for six months in 2010. Also, capital funding for meter and Orion
reading technology doubled in 2011 to $300,000.
The Meter Department concentrated on large meter testing and replacement in 2011 with the number
increasing by 18 from 2010. Since the large meters in the system account for a large portion of
consumption and revenue, it is extremely important to maintain reading accuracy and ensure proper
revenue to the Utility.
New customer meter sets increased in 2011, but water service taps again showed another large
decrease. This is likely due to the fact that many home sales were of previously unoccupied or
foreclosed properties with very little new home construction occurring.
In 2011, the staff again dedicated more labor-hours performing meter take-outs, due to the high
volume of vacant or foreclosed properties. Additional staff time was spent locating water services for
the WE Energies‟ Renew Racine Project. Also, the new cross connection control inspection program
began in early summer.
Bulk water sales from tanker fills at the Service Building and distribution hydrant fill stations, totaled
$22,140 in 2011 almost doubling in revenues from 2010.
The Utility billed approximately $19,228 to customers for purchased meters or for damaged/broken
equipment (i.e. iced damaged meters).
Seasonal meters sets (partial year customers) generated $101,112 for the RWU.
For 2011, Meter employees continued to separate metals from the old removed meters for recycling.
Recycling of meter scrap metal generated $14,162 for the Utility to supplement capital funds for
meter purchasing.
The Meter Department remains an integral part in the operation and viability of the Racine Water &
Wastewater Utilities. It is often said that a meter department serves as the “cash register” to water
department operations. Here in Racine, that is very true; and, in fact, meter equipment and reads taken by
the meter department staff are also used for the basis of billing charges for the RWU and several sewer
districts in the outlying areas.

The Construction Department consists of twelve full-time employees; the Construction Supervisor, the
Assistant Construction Supervisor, three Machine Operators, and seven Utility Workers. The
Construction Department works closely with the Engineering Department, and is overseen by the Chief
Engineer.
The main duties of the Construction Department are to:
Perform regular system maintenance
Repair main breaks, and replace or repair broken valves, hydrants, and water services
Respond to service calls and Digger‟s Hotline Locate requests
Perform leak detection in the distribution system
Distribution System Maintenance & Repair
The distribution system averages over 100 water main breaks per year. Repairing these breaks consumes
a large portion of the Department‟s time during the winter and summer months, when most main breaks
occur. As breaks lessen over the spring and fall months, the Department then focuses on distribution
system maintenance.
To maintain the system and keep it in good working order, the Department annually exercises valves,
operates hydrants, and checks water services. Maintenance of the distribution system is logged via the
GIS system, which makes for quick and easy reporting. The Department works with city, county, and
state paving contractors to ensure all valves and hydrants are in good working order prior to the
placement of new pavement.
Maintenance and repair work performed in 2011 included, but was not limited to, the following:
77 main breaks dug and repaired
1,415 valves exercised
83 Broken valves repaired or replaced
15 new valves installed
4,028 hydrants exercised
390 hydrants flushed
51 broken hydrants repaired or replaced
2 new hydrants installed
217 water services repaired
21 lead services replaced
930 hydrants painted
Service Calls
The Construction Department responds to calls 24 hours a day, 365 days a year from residents, plumbers,
contractors, and other state and municipal entities.
For example, in 2011, the Construction Department responded to 38 water service leaks, and performed a
good portion of the 15,895 Digger‟s Hotline Locate requests received by the Utility. The Department also
responded to a variety of other requests, including infrastructure adjustments for road building contractors
and water main connections for developers.

ENGINEERING DEPARTMENT
The Engineering Department consists of six full time employees; the Chief Engineer, Civil Engineer II,
two Engineering II Technicians, an Engineering Technician/Inspector, and an Engineering Aide. The
Department also includes two part time construction inspectors who work seasonally. The Department
downsized in early 2011 by removing a Civil Engineer position through attrition.
Though the Engineering Department fills a lot of roles for the Racine Water Utility, its main duties are to:
Design and manage water main replacement projects
Replace lead services
Respond to Digger‟s Hotline Locate requests
Plan and Coordinate work done by other public and private entities
Provide technical assistance to other RWU departments
Update and develop the Utility‟s GIS system
Water Main Replacement Projects
To keep up with failing water mains that have reached the end of their useful life, the Engineering
Department designs and manages some 2-3 million dollars in Capital Improvement Projects each year.
Main replacements are typically split between several contracts and spaced throughout the year. Spring
contracts focus on main replacements where road improvements are scheduled to be performed later that
year, and summer/fall contracts focus on replacing the most problematic mains in the system.
Whether or not a main needs replacement depends on several factors, including:
Pipe age, diameter, and material
Break frequency and recent recurrence level
Condition of the street, and timeline of potential street improvements
Break severity and associated repair costs
Impact to distribution system and customers
The Utility typically experiences over 100 water main breaks per year. Data on each break, such as the
pipe material type and cause of break, is recorded by the Engineering Department and then used to help
prioritize main replacements each year. Figure 1, below, shows historical yearly main break totals.

[91]
As shown in Figure 1, the Utility experienced 77 water main breaks in 2011, a relatively low number
compared to the previous decade, and the third lowest number of breaks in the past 35 years.
The Utility began its yearly water main replacement capital improvement project in 1986, as indicated in
Figure 1. A water main break trendline is shown for those years prior to 1986, and a second trendline is
shown for years 1986 to present. Comparing these trendlines, the water main replacement program
appears to have reversed the trend of increasing water main breaks.
2011 water main breaks, summarized by month and break type, are show in Figure 2, below.

The table below lists the contracts designed and managed by the Engineering Department in 2011, with
the majority of these contracts pertaining to water main replacement. A RWU replaced a total of 11,779
feet of water main at a cost of $2,281,000.
Lead Service Replacement
As part of its Capital Improvement Program, the Engineering Department replaces dozens of lead services
each year. Lead replacements are typically performed on water main replacement projects, where the
lead service is replaced in conjunction with the installation of the new water pipe. In some instances, the
old lead service is replaced but the old water pipe is left in place. This typically occurs when the old pipe
is still in good condition, but the old lead service is replaced in anticipation of a street reconstruction

project. The Engineering Department replaced 151 lead services in 2011 through its CIP projects. It is
estimated 10,560 active lead services remain in the Utility‟s distribution system.
Digger‟s Hotline Locates
Like other utilities, the Water Utility must respond to Digger‟s Hotline Locate requests. Locating duties
are split between the Engineering, Meter, and Construction Departments. 15,895 locates were performed
by the Utility in 2011, with the Engineering Department performing approximately 2,300 of the total.
Plan and Coordinate Work by Others
In addition to its own projects, the Engineering Department works closely to see that projects funded by
other public and private groups are properly and successfully completed. These types of projects include:
Development of new subdivisions
Development of commercial sites
Road and highway improvements
Utility construction
Site remediation
When new mains are to be constructed by others, outside engineering groups first submit design plans to
the department for review and approval. Then, during
construction, we help resolve any problems that arise, and also
ensure that any newly installed mains are properly pressure
tested and safe water sampled.
Upon completion of the project, we verify that all newly installed
infrastructure is in good working condition and up to
specification before accepting that infrastructure into our
distribution system.
One recent example of this type of coordination was the
construction of the new Pick „N Save in Mount Pleasant. The
Engineering Department worked closely with the developer‟s
engineers and contractors to successfully work around the problems encountered during
construction, and see that the project was completed on-time and per specification.
Figure 4 lists the water main installations that were performed by developers in 2011.
Technical Assistance
The Engineering Department works closely with other departments to provide technical assistance when
needed, including:
Locating of hard to trace water mains
Referencing and utilizing information found in our historical archives
[93]
GIS Web App
Tracking and logging of work done by field operations
Investigating and troubleshooting discrepancies in the distribution system
Creating reports, maps, graphics, and other displays
Geographic Information System (GIS)
The Utility‟s GIS system is dynamic, ever-improving, and requires daily maintenance to keep its
information correct and up to date. The GIS allows the user to view, graphically, all the components of
the Utility‟s distribution system, including water mains, valves, water services, and hydrants. The GIS
hosts information such as the age of a piece of pipe, or whether a water service to a customer‟s home is
lead or copper.
The GIS system is accessible via the internet, which allows any utility employee armed with a laptop
instant access to all the information they‟ll need
to perform a digger‟s hotline locate or investigate
a problem.
A recently added feature is the ability to record
the daily operation and maintenance performed
by field personnel, and then query that data. For
example, should a customer call to notify the
Utility of a problem, the GIS user can run a query
to see if any work was done in the area. The GIS
will show what type of work was performed, the
date and time, and even the exact valves or
hydrants that may have been operated.
