Welcome to the Sanitary Engineering Department
The Allen County Sanitary Engineering Department is split into two divisions, the Wastewater Treatment Division (WWTD) and the Wastewater Collection Maintenance Division (WWCMD), with the main office of the Sanitary Engineer coordinating the day to day operations.
The WWTD is responsible for the maintenance and operations of all wastewater treatment plants and the operations of the sludge management program. The WWTD operates three major treatment plants located in Bath, Shawnee and American Townships and three smaller package treatment plants located in Bath and Richland Townships.
The WWCMD is responsible for the maintenance and operation of approximately 170 miles of sewer lines, 54 high pressure sewage lift stations and 150 low pressure lift stations located within American, Auglaize, Bath, Jackson, Monroe, Perry, Richland and Shawnee Townships.

This project was initiated by many property owner complaints to the Perry Township Trustees about the unpleasant odors and sewage being discharged to an unnamed ditch located within the project area. The Allen County Sanitary Engineers in conjunction with the Allen County Health Department conducted a field sampling investigation of the project area. Field samples were tested and determined to have high levels of fecal coliform and biological oxygen demand (BOD). An informational meeting will be scheduled to inform all property owners of the unsanitary conditions, and what can be done to alleviate the problem.
The American-Bath Wastewater Sewer Subdistrict originated from the need to gain control of the septic system discharges and the rapid growth of the American and Bath Townships in the late 1960’s. The original plant came online in 1968 and was designed to treat .4 MGD (Million Gallons Day). Due to continued growth the old plant underwent expansion in 1988 to increase its capabilities to .6 MGD.
With the ensuing contract with the Village of Cairo to treat their wastewater, and the increase in customer base, the decision was made to build a new facility and abondon the old plant. Therefore in 1996 the current US Filter based Orbial Oxidation Ditch Plant came online with the Design capability of 1.5 MGD.
In 1974, the American II Wastewater Treatment Plant was put on line. The plant was designed as a conventional activated sludge plant.
The plant is designed for. 8 Million Gallons per day and consists of bar screens and parallel grit chambers followed by comminutors. Four lift pumps carry the sewage to parallel primary settling tanks. The primary tanks removed settled and floating solids that are stored in the sludge storage tank. The sewage flowed into the aeration tanks where air is introduced and mixed. In 1991, walls were constructed to divide the aeration tanks into two tanks; contact and stabilization. This modification of the tanks increased the treatment capabilities of the system.
The sewage then passes into the final settling tanks where solids settle and are returned to the stabilization tank, or pumped to the sludge holding tank. The final tank effluent then passes through two parallel microstrainers where it is filtered to 10 microns. The filtered effluent is chlorinated to kill bacteria and dechlorinated before discharged to Dug Run. The sludge is pumped from the sludge holding tank to an anaerobic digester where it is digested prior to applying it to farmland.
The Allen County Sanitary Engineering Department took on the costs to undertake this project in 2011. An agreement was made between the Village of Harrod and Allen County to collect and treat areas within the Auglaize Township Sewer subdistrict #1.
In September of 1997 a contract was agreed upon between the Village of Cairo and Allen County for the treatment, and operation and maintenance of the newly constructed sanitary sewer within the Village of Cairo. This agreement includes the Village of Cairo maintaining ownership of the sanitary sewer with the Allen County Sanitary Engineer treating the sewage flowing from the Village to the American/Bath Wastewater Treatment Plant. Also included in this agreement, the County will be responsible for both the operation and maintenance of the sanitary sewer for many years to come.
This project is owned and maintained by the Allen County Sanitary Engineering Department and flows are connected to the County’s system for collection and treatment. The Shawnee #2 Wastewater Treatment Plant treats the sewage in this subdistrict.
This is an assessment project that was initiated by many property owner complaints to the Perry Township Trustees about the unpleasant odors in the air. Perry Township then contacted our office about an initial sewer design that would help eliminate the problem. The project boundaries for this project consist of Clyde Avenue, Kingston Avenue, Charledon Avenue and sections of both 8th and 9th Streets. Procedures for this project are scheduled to start in the beginning of 2002 with a preliminary estimated cost of construction at $1,039,140.00. State grant funds, a local government match and user debt service will provide funding for this project.
In February of 2009 a contract was generated between the Village of Ft. Shawnee and Allen County for the treatment of wastewater from the newly constructed sanitary sewer within Allen Township. This agreement states that the County is responsible for the ownership, construction, operation and maintenance of the sanitary sewer.
In September of 1997 a contract was generated between the City of Lima and Allen County for the treatment of wastewater from the newly constructed sanitary sewer within Bath Township. This agreement states that the County is responsible for the ownership, construction, operation and maintenance of the proposed sanitary sewer.
The Allen County Sanitary Engineering Department took on the costs to undertake this project in 2004. An agreement was made between the Village of Lafayette and Allen County to collect and areas within the Allen East School district.
A recent Geograpic Information System (GIS) Project was completed on the Shawnee II Wastewater Collection System. The public is now able to view a computer generated map displaying our departments facilities.
In 1974, the Shawnee II Wastewater Treatment Plant was put on line. The plant was designed as a conventional activated sludge plant with a Zimpro unit to process sludge. The plant is designed to treat 1.2 million gallons per day and process sludge at the rate of 10 gallons per minute.
In 1994, the upgrade and expansion of the plant was complete with a two tank SBR (Sequencing Batch Reactor). The new plant utilized the existing grit chamber and pump room and increased the pumping capacity to 2.0 million gallons per day design flow with wet weather pumping capacity of 3.5 million gallons per day.
Shawnee Oaks Wastewater Collection Sewer Subdistrict
In August of 1966 a contract was generated between the Village of Cridersville and Allen County for the treatment of wastewater from the newly constructed sanitary sewer within Shawnee Township. This agreement states that the County is responsible for the ownership, construction, operation and maintenance of the sanitary sewer.
In March of 2014 a Sewage Treatment Agreement was signed by the mayor for the Village of Cridersville to have wastewater treatment continued
This is a project within the project boundaries of the Village of Beaverdam, which includes a Water Tower, a Waterline Extension and two Lagoons to accommodate the development in the area. Fanning and Howey Associates, Inc., in Celina, Ohio, is providing professional design services for all three developments.
Speedway SuperAmerica LLC took on the cost to construct a sanitary sewer collection system within Richaland township in 2006. An agreement was passed to allow the Village of Beaverdam to treat and bill customers within the service area. The Village then remits a conveyance fee to the County on a quarterly basis.
The Ohio Environmental Protection Agency (OEPA) has brought about this project after a water quality survey was conducted on the Upper Auglaize River. A portion of this survey was done from June 19, 2000 thru August 21, 2000 of an unnamed tributary that flows through Westminster and into the Upper Auglaize River.
A study was conducted by Kohli & Kaliher in September 2007 to determine whether the Woodbriar plant should get upgraded or abandoned. The treatment plant was ultimately abandoned and flow was redirected by force main to the Findlay Road sewer system.
