Superintendent’s Note
In 2017, the Springfield Wastewater Treatment Plant saw an average daily flow of 17.2 Million Gallons per Day (MGD). The plant rain gauge recorded 73.3 inches of rain for the year. We have witnessed a steady decline in daily flow that is directly related to the City’s annual sewer-lining program that continues to eliminate inflow and infiltration (I&I).
With the completion of the Plant’s expansion project in early 2015, having added the Excess Flow Interceptor Structure (EFIS), Final Settling Basin #3, Primary Digester #4, and the compressible media High Rate Treatment (HRT) facility, the plant now has virtually eliminated all internal wet weather CSOs.
As part of the Long Term Control Plan, design of the Erie Interceptor Express Sewer and new South Erie Lift Station were finished and construction is underway. Of the 13 active lift/pump stations placed around the City, four will be eliminated by way of the construction of the South Erie Lift Station. Anticipated completion of the project is Fall of 2018.
The plant staff converted three of our high mast lights from the older style halogen lighting to LED lighting. This has cut the high mast light energy use by 55%, and also provided much better lighting for our operators as they maintain the plant during the night. A total of five of the six high mast lights have been converted; we hope to complete the conversion of the last high mast light in 2018.
We conducted a Capability to Remove Phosphorus Study and gathered data to submit to the Ohio EPA to outline the cost and challenges associated with removing the nutrient.
The plant did not violate any of our Ohio EPA-issued National Pollutant Discharge Elimination System (NPDES) permit limits in 2017.
The end of 2017 was marked by both my promotion from Assistant Superintendent to Superintendent, and the retirement of William W. Young, the outgoing WWTP Superintendent. He has been my predecessor and mentor, but more importantly, an invaluable asset to the City and to the WWTP, who will be missed.

Springfield Wastewater Treatment Plant
The Wastewater Treatment Plant is an advanced secondary treatment plant located at 965
Dayton Avenue in Springfield, Ohio. The plant was originally constructed in 1935 as a
primary treatment facility with major improvements in 1961, 1972, 1988, 1995, 2000,
and 2015. The facility is presently designed for an average day capacity of 25 MGD
(Million Gallons per Day), with an actual average flow of 17.2 MGD. During rain and
storm water events, we can treat a peak flow of 40 MGD through the main plant and an
additional 100 MGD through the HRT system.
Flow enters the plant through four large interceptor sewers, three of which connect after
the Excess Flow Interceptor Structure (EFIS). All influent flow of 40 MGD or below
flows through EFIS to the main plant via two automated control gate valves into the bar
screen channels. All influent flow above 40 MGD must pass through four horizontally
raked bar screens before going over an inner weir to the HRT system. The HRT flow
receives primary treatment and disinfection prior to discharging to Mad River.
Physical treatment starts with two parallel Huber, 5/8-inch bar screens that remove larger
objects from the waste stream. These screenings are raked behind the screens into two
Vogelsang X-Ripper twin-shaft grinders for shredding. The screenings then drop into a
screw press where they encounter water sprayers to remove organic material, before
being dewatered and discharged to a dumpster and hauled to a landfill. The flow then
proceeds to two parallel, aerated grit basins where the inorganic solids are removed,
cleaned, and also hauled to a landfill. One screen and grit basin is in operation during
normal flow up to 25 MGD, after which point both screens activate.
The flow is then divided into three primary clarifiers for organic solid settling and oil and
grease removal. The organic solids settle to the tank bottom while any floating oil and
grease are skimmed from the tank surface; the organic matter, oil, and grease are then
pumped to four primary digesters.
Flow from the primary clarifiers is then pumped with fixed discharge pumps to two
trickling filters, 200 feet in diameter, where biological treatment begins. The discharge
from these filters is pumped into a complete mixed activated sludge (CMAS) system
through a combination of 8.2-foot diameter screw pumps. The CMAS system consists of
four 1.25 million gallon (MG) aeration tanks which then flow into three secondary
settling basins sized at 1.4 MG each. The settled material, the activated sludge, is
returned to the head of the CMAS system (Return Activated Sludge - RAS) to seed the
incoming trickling filter effluent. Excess sludge eventually accumulates beyond what is
required for treatment and is called Waste Activated Sludge (WAS). WAS is removed
from the treatment process to keep the ratio of biomass to food supplied (wastewater) in
balance. It is pumped into the primary tanks from the secondary clarifiers, acting as a
flocculent for the primary sludge.
6
Discharge from the secondary clarifiers is then piped to a 400,000-gallon disinfection
tank where, during the months of May through October, sodium hypochlorite is added for
disinfection. To neutralize the residual chlorine, flow continues to a de-
chlorination/aeration tank where sodium bisulfite is added. Blowers are used to aerate
the effluent when necessary to assure proper dissolved oxygen levels prior to discharge
into Mad River. During the months of November through April, these tanks continue the
normal course of flow but without the chemical addition.
Settled solids (sludge) removed from the primary clarifiers are pumped into four primary
digesters for treatment, three sized at 420,000-gallons, and one sized at 1.35 MG. In
these primary digesters the sludge is heated, mixed, and digested under anaerobic
conditions for destruction of organic matter. After the sludge is treated it flows into a
700,000-gallon secondary digestion tank for storage. The gas produced in this process
(methane) is used for the heating of the primary digesters and is stored in the secondary
digesters’ floating dome.
The final stage of treatment is to remove as much water as possible from the digested
sludge in preparation for reuse. To do this, polymer is added to the sludge, aiding in the
dewatering process. It is then introduced to the belt filter press where it passes several
pressure zones for water removal. This dewatered sludge is then pumped to an enclosed
storage structure until hauled away for beneficial agricultural land application.
Licensed operators oversee operation of the plant 24 hours per day, seven days a week.
They are assisted with their duties by a computerized automated control system
consisting of a series of 11 Programmable Logic Controllers (PLC) with 4 personal
computers using WonderWare Factory Suite, an integrated component-based
Manufacturing Management Information (MMI) System. Integrated in this system is the
capability of automatic control, data collection, and manual overrides for most of the
process areas.

Plant Improvement History
1935
The Springfield Wastewater Treatment Plant was originally constructed and placed into operation with preliminary and primary sewage treatment, with single stage anaerobic sludge digestion followed by a vacuum filter. 1961
An upgrade project was completed which provided secondary biological treatment with trickling filters. Hydraulic capacity was increased to 25 MGD (million gallons per day) daily average flow, and 37.5 MGD peak flow. The anaerobic digestion system was upgraded to two stages with the addition of a secondary digester with a floating cover for gas storage. 1972 The preliminary treatment process was expanded and upgraded to dual units for screenings and aerated grit removal. A chlorine contact basin and storage building for one-ton containers was added to improve the disinfection process. 1988 The plant was upgraded to advanced secondary treatment by adding complete mixed activated sludge in tandem with the trickling filters. Dechlorination and post aeration were added after the disinfection process. This project also included a new Operations and Laboratory (O&L) building. 1995 Mechanical sludge dewatering by belt filter press and covered storage were constructed to replace earthen lagoons. Land application of sludge was transferred from in-house staff to private operators. 2000 At this time, the following improvements were conducted: -Combined sewer overflow screening and other headworks improvements. -Anaerobic digester structural renovations and new process heating system. -Effluent sewer expansion for peak flows handling. -Conversion from gaseous chemical disinfection to aqueous chemical disinfection. -General repair and renovation to buildings and structures. -Installation of mechanizations and electronics for a SCADA system for process automation. 2009
An Effluent Pump Station was added.

2015 At this time, the following improvements were conducted: - Excess Flow Interceptor Structure (EFIS) with two new influent flow control gates and four horizontally-raked bar screens added. - Two Huber Bar Screen replacements added. - Primary Digester #4 with a capacity of 1.35 MG added. - Three Aerated Grit Blower replacements added. - Final Settling Basin #3 with a capacity of 1.4 MG added. - Both Belt Filter Presses (BFP) rebuilt. New chemical polymer pumps added. Solids storage area roof replaced and all biosolids conveyors replaced. - 100 MGD High Rate Treatment (HRT) System added. - Chemical Building added to house both sodium hypochlorite and sodium bisulfite and new peristaltic pumps added to feed chemicals. - New maintenance shop added. - New main plant generator added. Generator can power entire plant and all processes (minus HRT) in the event of a power outage. - Upgraded SCADA system to newer version with increased control and trending capabilities. - General repair and renovation to existing buildings and structures.

Septage Receiving Station
The Wastewater Treatment Plant accepts residential septage from registered
haulers in the community. Administrative Memorandum 61.4 and the Codified
Ordinances regulate this process. These regulations state that only residential septage
may be discharged, trucks must be 4,000 gallons or less in capacity with no side
discharge, and each user is permitted to discharge no more than 12,000 gallons per day.
The septage is discharged directly into an 84-inch sanitary sewer before entering
the plant headworks. Septage is randomly sampled and analyzed for metals and other
constituents that may be harmful to the plant. This ensures that the received septage has
no adverse effects on the treatment plant processes. The Springfield Wastewater
Treatment Plant is located in a valley, confining the odors to the plant’s preliminary and
primary treatment area.
The Septage Hauler’s Receiving Station was also redesigned during the 2015
expansion project. We are now able to accept septage during normal dumping hours
(8 am – 8 pm) with virtually no restraint, in contrast to the pre-construction condition that
prohibited dumping during elevated plant influent flow. This was achieved by installing
the new septage receiving line after the influent control gates so that dumping is no
longer restricted to times during low/normal plant flow.

2017 Maintenance Report
The maintenance staff consists of personnel that perform a wide variety of tasks in order
to maintain the operation of the main plant and pump stations. There are three
Maintenance Mechanic II personnel who perform our technical mechanical maintenance
tasks. They are supported by two Maintenance Mechanic I workers and three Relief
Operators that provide assistance when needed and perform the minor maintenance tasks.
The Relief Operators could be called to operate the plant at any time. There are two
Electricians that perform electrical and PLC repairs with one also designated to perform
the communications repairs throughout the City. In 2017, we experienced the following
position vacancies: 1-Plant Operator II, 1-Maintenance Mechanic I.
During this year, the designs for the Erie Express Sewer and new South Erie Lift Station
were completed and construction has begun. Project completion is anticipated to be in the
fall of 2018. When the new South Erie Lift Station comes online, it will assume the
incoming flow of four existing stations, which will in-turn be decommissioned and razed.
Those stations are:
Skinner Lane Pump Station – 1906 First St.

Sewage Lift/Pump Stations
There are 13 sewage lift/pump stations located throughout the City that fall under the
control of the Wastewater Treatment Plant. The average daily sewage flow from these
stations to the Wastewater Treatment Plant in 2017 was 2,509,656 gallons per day (gpd).
The monitoring of the lift/pump stations is done by radio communication with the
plant SCADA system. Each of the stations can be individually monitored for the various
data that is provided to the system. The plant SCADA system will call the operator’s cell
phone with any alarms requiring immediate attention. The newer stations can also be
controlled remotely through the plant SCADA system.
As another means of verification, a bi-weekly inspection is performed on all of the
stations. Each station is checked for its overall running condition, appearance, and odor.
The plant maintenance staff utilizes a dedicated repair truck to perform any required
work. This truck is equipped with a crane, tools, welding equipment, entry equipment,
and any other equipment necessary to service the stations.
To ensure that stations can operate during power outages or loss of pumping,
personnel also have two 4-inch portable diesel pumps, one 6-inch portable diesel pump,
and three portable backup generators available. Eleven of the lift/pump stations have an
emergency generator hookup for use during power outages and most of the stations are
set up for emergency pumping. Both Airport and Airpark Ohio pump stations have
backup generators onsite due to their remote locations.

Municipal Industrial Pretreatment Program
The Municipal Industrial Pretreatment Program (MIPP) exists to protect the
Wastewater Treatment Plant and waterways from harmful substances that could be
discharged from local industrial customers. The Springfield MIPP became effective
March 1, 1985. The regulating authority for the program comes from Chapter 916 of the
Codified Ordinances in conjunction with the Federal Water Pollution Control Act, as
amended (33 U.S.C. 1251 et.seq.) and the Ohio Water Pollution Control Act (O.R.C.
Section 6111). In 1990, a MIPP Coordinator position was added to execute the program.
The Coordinator is given latitude to execute the program as needed; however, the Plant
Superintendent provides program oversight while the Sewer Use Ordinance names the
Service Department Director as the enforcing agent.
Through this program, industries are classified according to their manufacturing
process and their ability to negatively impact the plant. Currently the program monitors
eight categorical significant industries, seven non-categorical significant industries, and
one non-significant industry. Automated samplers are used to collect composite samples
of industrial sewer users discharges throughout the year. The Wastewater Treatment
Plant laboratory staff analyze these samples for various parameters such as metals, pH,
ammonia, biochemical oxygen demand, and suspended solids. A secondary function of
this program is to investigate matters related to unknown discharges or spills that could
enter the collection system or area waterways, collection and monitoring of combined
sewer overflows, and other surveillance as required.
The program is funded through the operating and capital budget of the
Wastewater Treatment Plant. There are currently no specific funds from licenses,
permits, or fines directed specifically to the operation of the program. Any funds
collected from the surcharge-monitoring program are placed directly in the Sewer Fund.

Accomplishments During the 2017 calendar year, there were two Industrial Sewer Users in significant non-compliance. Both Significant Industrial Users (SIU’s) were Categorical SIU’s. Each of them had a faulty part in their respective pre-treatment processes that failed resulting in the violations. However, since the repairs were made, no further issues have been found. All of the SIU’s and one Non-SIU were inspected. Additionally, all permitted users were sampled in accordance with the MIPP and Local Discharge Permit requirements. We continued the sampling program that began in 2016, in order to revisit the Local Limits that are published in Chapter 916 of the Codified Ordinances of the City of Springfield, Ohio. We also continued to investigate sources of mercury and silver from various points within the City sewer system to satisfy a new NPDES permit requirement. The City continued to work with one SIU on installing flow proportional sampling equipment, and this facility will complete its program once the new Erie Express Sewer is installed. Program personnel sampled each of the significant non-categorical industries at least three times annually, the non-significant industries at least once annually, and the categorical industries biannually. Sampling events typically ran from Monday through Friday, yielding four composite samples. In all, there were 401 sampling events and 15 inspections. In 2017, the Springfield Wastewater Treatment Plant experienced no instances of pass through or interference. Problems: There were no direct problems from Industrial Sewer Users in implementing the program requirements. Most industrial violations of the discharge limits were minor and resulted from operational and/or equipment failures. Program Modifications: The City submitted a Program Modification Request outlining previous changes and seeking approval, allowing for the issuance of Monitoring Waivers to compliant industrial users that demonstrate a need. The City also submitted a request for updating the local limits and revising the limits for oil and grease. The City reviewed pertinent changes to pretreatment regulations over the past year. The most significant change was the Dental Amalgam Rule that was reinstated in mid-2017 by President Donald Trump. The City is currently working on information letters to be sent to all pertinent dental offices.
