Westphalia WWTL - Secondary Wastewater Treatment in Westphalia Township, Michigan

Westphalia WWTL is a municipal wastewater treatment plant located at 173 North Willow Street in Westphalia Township, Clinton County, Michigan. The facility serves a population of 819 and operates as part of the region's water infrastructure. The plant provides secondary treatment, which is the standard level required by the US Clean Water Act for municipal facilities of this scale. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids before discharge. The plant's designed capacity is 454.25 volume units, matching its discharge volume, indicating consistent operation. The treated effluent is discharged into local surface waters that drain into the Grand River watershed, ultimately reaching Lake Michigan. This contributes to the protection of downstream aquatic ecosystems and supports water quality in the Great Lakes basin.

The plant discharges into local streams that flow into the Grand River, which empties into Lake Michigan. Lake Michigan is a major freshwater resource supporting diverse aquatic life, including fish species such as lake trout and whitefish. The watershed is ecologically sensitive, and secondary treatment helps reduce nutrient loading that could otherwise contribute to algal blooms in the lake.
