Gomer Sewer Improvement Area

The project area is an unincorporated area located along Pike Run in Sugar Creek Township. The Ohio Environmental Protection Agency (OEPA) has documented nuisance conditions within the area which have violated OAC 3745-1-04 (State Water Quality Standards) due to off lot discharge of sanitary wastes. Individual homes are served by cesspools, septic tanks or on-site home units which discharge off-site to various storm sewer outlets. Pike Run at Gomer is on the list of prioritized impaired waters in the “OEPA 2014 Integrated Water Quality Monitoring and Assessment Report” due to non-attainment of human health and recreation assessment criteria as a Class B, Primary Contact for Recreation use stream.

On May 15, 2015 notification was sent to OEPA for review for the General Study outlining alternatives to resolve the water quality violations.

July 2022: Construction Completed.

Shawnee Sewer Sub-District SECAP

This is a capital improvement project that was developed to eliminate the Sanitary Sewer Overflow (SSO) throughout the Shawnee area. SSO’s are discharges of raw sewage from municipal sanitary sewer systems. SSO’s release untreated sewage into basements or out of manholes and onto city streets, playgrounds and into streams before it can reach a treatment facility. 

Example of an SSO within Allen County

Manhole and Mainline Inspections were done to determine problematic areas where infiltration is occurring.

Lateral Inspections were completed by placing a portable camera within the lateral through a clean out. Once the camera has viewed the entire length of the lateral, all deficiencies are recorded and our office will give written notice to the property owners of repairs that need to be addressed. It is the responsibility of each property owner to make repairs to the laterals, outside of the road right-of-way, within ninety days.
