1.0 EXECUTIVE SUMMARY
The City of Pitt Meadows holds a permit to operate its water utility from the Fraser Health Authority (FHA). In 2012, the city was mainly supplied by the Coquitlam watershed and treated by Metro Vancouver. In accordance with the requirements of the BC Drinking Water Regulation, the city’s operations department takes weekly water samples from eight stations which are sent to the Metro Vancouver laboratory for testing. Results are returned to the city on a weekly basis as documented in this annual report. In 2012, the City of Pitt Meadows water system met all regulatory requirements for drinking water quality as set out by the BC Drinking Water Protection Act. All water quality objectives suggested by Health Canada were also met:
No samples tested positive for E. coli.
100% of the samples had 0 Total Coliform per 100 mL.
The annual average Total Trihalomethane results ranged between 28 and 34 parts per billion (ppb), less than the Health Canada guidelines of 100 ppb.
The annual average Total Haloacetic acid results ranged from 28 to 49 ppb, less than Health Canada’s suggested 80 ppb.
In conclusion, the water quality in the City of Pitt Meadows was quite good in 2012.

2.0 INTRODUCTIONS
This is the City of Pitt Meadows (PM) annual Drinking Water Quality Report for 2012. It is prepared for the Fraser Health Authority (FHA) as well as for public information.
3.0 BACKGROUND
3.1 Regulating Authorities
PM holds a permit to operate its water distribution network from the FHA (Appendix 8) and adheres to the provisions of the Local Government Act. Water quality requirements are stipulated by the Drinking Water Protection Regulation (DWPR). The drinking water officer may also issue orders for non compliance and or health concerns. 3.2 Distribution System
PM’s water distribution network is over 111 kilometers long and serves a population of approximately 17,500 residents.
Water Supply
The primary water supply source is the Coquitlam watershed. Water supply can also come from the Metro Vancouver’s other watershed sources (Capilano & Seymour). The water arrives via Haney Mains 2 and 3. Water supplied by both Haney Main 2 and 3 is re-chlorinated at the Pitt River Secondary Disinfection Station prior to arriving in the municipal water distribution system. Water quality is anticipated to improve with the new UV disinfection plant in operation at Coquitlam Lake.

Maintenance
In a unidirectional fashion, using valve isolation, all water mains were effectively flushed. Dead end lines that are not looped received special attention. Sodium thiosulphate was used to ensure the absence of chlorine residual as the water being flushed was introduced into the environment. An automatic flush valve at the end of the long run on Rannie Road engages for 2 hours twice every day to ensure the presence of chlorine residual. Additionally, the line on Rannie Rd was swabbed from Thompson Rd to the end in November 2010. The results from this swabbing have showed noticeable improvements in chlorine residual. Unidirectional flushing has been revised futher with the aid of computerized modeling and feedback from last year’s program to improve effectiveness. All City owned backflow devices and assemblies were tested and repaired as required by a certified tester. All components of the six pressure regulating stations and the single booster station were maintained on a regular basis to ensure proper operation. This maintenance included the cleaning of inline and body strainers, function of Clayton valves and pressure relief valves, air valves. All 469 fire hydrants and 4 standpipes owned by the City were fully maintained in 2012. The hydrants received a scheduled “A” or “B” service and approximately 112 were power washed and painted. The City has 966 mainline and service valves in the distribution system that were exercised and maintained as necessary.
Repairs and Upgrades
Currently asbestos cement (AC) mains are being replaced by ductile iron mains (DI) on a yearly basis with all AC mains scheduled to be replaced by 2025. Projects in 2012 included:
1) Replaced 270 meters of CI and AC main on Ford Rd with Ductile Iron pipe. 2) Replaced 290 meters of AC main on Blakely Rd with Ductile Iron pipe.

4.1 Bacteriological Monitoring
Samples are analyzed for fecal coliform, total coliform and heterotrophic plate count (HPC). BCSDWR Microbiological Standards are listed in Table 2.
Table 2: BCSDWR Microbiological Standards
Parameter Occurrence Standard
Fecal Coliform 0 Less than 1 fecal coliform per 100 mL
Total Coliform 0 0 total coliform per 100 mL
At least 90% of samples have 0 total
coliform per 100 mL and no sample has
more than 10 fecal coliform per 100 mL
Bacteriological Results
Appendix 4 illustrates the bacteriological requirements were met in 2012.
4.2 Chemical and Physical Monitoring
Monitoring of the City’s distribution system is conducted by Metro Vancouver. Samples are screened for temperature, pH and turbidity. Monitoring of the source water and Metro Vancouver transmission system is conducted by the Metro Vancouver Water District (MVWD) and Metro Vancouver. Table 3 illustrates which BCSDWR guidelines were not met.

Temperature of water was generally acceptable, the only times that the water temperature was above the guideline was during the summer months. Temperature of water will affect the efficiency of water treatment processes. Low temperature decreases efficiency of treatment processes and high temperatures enhance the growth of nuisance organisms.

Total Haloacetic Acid results account for the by-products of the disinfection process from chlorine break down and are within the allowable limits. In comparison with previous years we see averages moving up and down across the municipality from station to station and year to year. Source water and Metro Vancouver improvement plans are determined by the MVWD and published in the MVWD Quality Control Annual Report, 2012.

Chlorine Residual Improvement Plan
Site 425 – This location is at the far north end of Pitt Meadows and has been a significant problem in the past. In mid November 2011, the City installed infrastructure to enable the ability to run a swab through the line to clear out contaminates within the pipe that could be impacting chlorine residuals. As indicated in the summary above, the chlorine residuals at this site have improved dramatically when compared with previous years. Combined with the auto flusher that was installed several years earlier, the lower residual problem in the north should be solved for the foreseeable future. Site 426 – This site will be checked for options to improve the flushing technique. If the number of failed samples continues to increase new options will be investigated.
Total Haloacetic Acid (HAA) Improvement Plan
Continue to monitor and review results. The Total HAA values dropped significantly over the course of the year with the highest value in the February test. In past years the values have been low in the summer and high in the winter. However, the results in
9
#112784v1
November 2012 were significantly lower than the previous year, possibly indicating significant improvement from the first year of the new flushing program. Further monitoring will be necessary to confirm that change.
5.0 EMERGENCY RESPONSE PLAN
The City of Pitt Meadows Water Response Plan is a document that contains detailed information for all emergencies that may be encountered including major disasters such as earthquakes and flooding. The following provides a brief overview of the plan:
Contamination
1) Metro Vancouver notifies the City of Pitt Meadows Works Department of some
form of contamination from municipal samples and or source samples. 2) The City will obtain the following information: -location where samples were obtained; -approximate boundaries of the affected area; -severity and type of contamination. 3) The Works Department will initiate notifications including the Fraser Health
Authority for the City of Pitt Meadows providing all available information. Evaluate with the FHA the need for a “boil water” notification.
4) Depending on the severity of the contamination: -isolate and flush the affected area with clean water. -make arrangements with the Metro Vancouver for the collection of repeat
samples as necessary. -conduct chlorine residual and bacteriological testing after the mains have been
flushed. -repeat the above until water supply meets normal testing levels. 5) If contamination is severe: -the Operations Superintendent will notify the Mayor of Pitt Meadows.
-if determined that a “boil water” notification is to be issued, prepare a document with press release and provide to the Director of Operations and Development Services. Provide notification to all schools, heath care centers, and care homes.
-the City will receive notification from the laboratory with results of the repeat samples and results of the species identification.
-contact the FHA and provide results of the repeat samples and the species identification.
-if the responsibility of the City of Pitt Meadows, the Operations Superintendent, in consultation with FHA, will initiate decontamination procedure.
10
#112784v1
-monitor decontamination procedure. 6) If the contamination appears to be of a suspicious nature, the City’s Operations
Director will notify the RCMP.
Turbidity
1) If a warning is received from GVRD or if the City identifies turbid water through monitoring, isolate the service area until turbidity passes or try to supply the area from a different source.
2) If a warning is issued, determine anticipated duration of event from GVRD. 3) Determine if necessary to issue a notification. If not, go to item 5. 4) If a notification is to be issued it must come from the Director of Operations
And Development Services in consultation with Fraser Health Authority on the notification notice with release information.
5) Flush the affected area with clean water. 6) Conduct chlorine residual and bacteriological testing after the mains have been
flushed.
Loss of Water
1) MVWD notifies of a system failure and or loss of supply.
2) Operations to determine the location, extent of service disruption. 3) Establish EOC if extent is widespread and service to be disrupted for extended
periods of time.
4) The Works Department will initiate notifications including the Fraser Health Authority for the City of Pitt Meadows providing all available information. Evaluate with the FHA the need for a “boil water” notification.
5) Public notice must be sent out it include all schools, long term care facilities
providing information on the disruption of service. 6) Fire Dept to arrange for alternative sources of water for fire fighting.
11
#112784v1
7) Planning and Operation Sections to determine impact on the distribution system. Determine if alternate sources can supplement until service is restored.
8) Arrange for water trucks and stage in appropriate areas for public distribution. 9) Monitor conditions with GVRD and when service is restored, determine is a boil
water notification is necessary.

6.0 WATER FLUSHING MESSAGE FROM FRASER HEALTH
A public health message from the Fraser Health Authority
Anytime the water in a particular faucet has not been used for six hours or longer, "flush" your cold-water pipes by running the water until you notice a change in temperature. (This could take as little as five to thirty seconds if there has been recent heavy water use such as showering or toilet flushing. Otherwise, it could take two minutes or longer.) The more time water has been sitting in your home's pipes, the more lead it may contain.
Use only water from the cold-tap for drinking, cooking, and especially making baby formula. Hot water is likely to contain higher levels of lead.
The two actions recommended above are very important to the health of your family. They will probably be effective in reducing lead levels because most of the lead in household water usually comes from the plumbing in your house, not from the local water supply.
Conserving water is still important. Rather than just running the water down the drain you could use the water for things such as watering your plants.
