WAYLAND STP - Secondary Wastewater Treatment Plant in Leighton Township, Michigan

WAYLAND STP is a municipal wastewater treatment facility located in Leighton Township, Allegan County, Michigan. The plant serves a population of 2,043 residents and operates under the regulatory framework of the United States Clean Water Act, which requires secondary treatment for municipal wastewater discharges. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant has a designed capacity of 1,135.62 units and currently treats an average daily flow of 984.21 units, indicating it operates below its maximum capacity. Secondary treatment typically involves activated sludge or trickling filter systems. The plant is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Michigan Department of Environment, Great Lakes, and Energy (EGLE), which set effluent limits to protect water quality. The treated effluent from WAYLAND STP is discharged to a local water body within the Lake Michigan drainage basin. The plant's location in inland Michigan means its discharge ultimately flows into the Great Lakes system, which supports diverse aquatic life and provides drinking water for millions. Protecting this watershed through effective wastewater treatment is critical for maintaining water quality in the region.

WAYLAND STP discharges into a tributary of the Kalamazoo River, which flows into Lake Michigan. The Kalamazoo River watershed supports diverse aquatic species and is an important recreational and ecological resource. The plant's secondary treatment helps reduce nutrient loading and organic pollution, protecting downstream habitats in the Great Lakes ecosystem.
