Allendale Charter Township Wastewater Treatment Plant, Michigan

The Allendale Charter Township wastewater treatment plant is a municipal facility located in Ottawa County, Michigan, serving a population of around 17,579. It is situated inland, more than 50 km from the Great Lakes coast, and treats wastewater from the township and surrounding areas. The plant operates under the US Clean Water Act, which requires secondary treatment for municipal facilities of this scale. The National Pollutant Discharge Elimination System (NPDES) permits, issued by the Michigan Department of Environment, Great Lakes, and Energy (EGLE), govern discharge limits and monitoring. The treated effluent is discharged into local waterways that ultimately drain into Lake Michigan, part of the Great Lakes system. The plant plays a key role in protecting the Grand River watershed and downstream aquatic ecosystems, including Lake Michigan's diverse fish populations and water quality.

The plant discharges into the Grand River watershed, which flows into Lake Michigan, one of the largest freshwater lakes in the world. The downstream environment supports diverse aquatic life, including lake trout, whitefish, and migratory species. Protecting water quality in this region is critical for maintaining the ecological health of the Great Lakes, which provide drinking water and recreation for millions.
