Webberville Lagoon Wastewater Treatment Plant, Leroy Township, Michigan

Webberville Lagoon is a municipal wastewater treatment plant located in Leroy Township, Ingham County, Michigan. The facility serves a small population of approximately 1,489 residents and operates under the regulatory framework of the U.S. Clean Water Act, which requires secondary treatment for all municipal plants. The plant provides secondary treatment, which typically involves biological processes to reduce organic matter and suspended solids. With a designed capacity of 946 m³/day and an average discharge volume of 757 m³/day, the facility operates well within its capacity. As a lagoon system, it likely uses stabilization ponds for natural treatment before discharge. The treated effluent is discharged into local surface waters that drain into the Grand River watershed, ultimately reaching Lake Michigan. The plant's inland location and small scale mean its environmental impact is localized, supporting the health of nearby streams and the broader Great Lakes ecosystem.

The plant discharges into local streams that are part of the Grand River basin, which flows into Lake Michigan. This watershed supports diverse aquatic life and is important for regional water quality. The small population served and secondary treatment help protect downstream ecosystems from nutrient pollution.
