Long Lake Area WWTF - Orleans Township, Michigan Wastewater Treatment Plant

Long Lake Area WWTF is a municipal wastewater treatment facility located in Orleans Township, Ionia County, Michigan. The plant serves a small population of 100 residents and is part of the region's rural wastewater infrastructure. Its location in the Great Lakes Basin places it within a sensitive freshwater ecosystem. The plant provides secondary treatment, which is the minimum standard required by the US Clean Water Act for municipal wastewater facilities. With a designed capacity of 121.13 million gallons per year and a discharge volume matching that figure, the plant operates at full capacity. As a small facility, it is subject to state-level NPDES permitting through the Michigan Department of Environment, Great Lakes, and Energy (EGLE). Treated effluent from the plant likely discharges to a local waterway that drains into the Grand River watershed, ultimately reaching Lake Michigan. The plant's operations are critical for protecting local groundwater and surface water quality in this rural agricultural area, supporting downstream aquatic habitats and recreational uses.

The plant discharges into a local tributary within the Grand River basin, which flows westward to Lake Michigan. Lake Michigan is a major freshwater resource supporting diverse fish populations, including lake trout and whitefish, and provides drinking water for millions. The surrounding area is primarily agricultural, so the plant helps prevent nutrient pollution and pathogen release into the watershed.
