Laingsburg Lagoon Wastewater Treatment Plant, Sciota Township, Michigan

Laingsburg Lagoon is a municipal wastewater treatment facility located in Sciota Township, Shiawassee County, Michigan, United States. The plant serves a population of approximately 1,258 residents and operates as a lagoon-based secondary treatment system. As a secondary treatment facility, Laingsburg Lagoon meets the standard requirements under the U.S. Clean Water Act, which mandates secondary treatment for municipal wastewater plants. The plant's designed capacity of 757.08 megaliters indicates it is sized for a small community, with current discharge volumes well within that capacity. The treated effluent from Laingsburg Lagoon is discharged into local waterways that ultimately flow into the Shiawassee River, a tributary of the Saginaw River system. This river network drains into Saginaw Bay on Lake Huron, part of the Great Lakes ecosystem. The plant plays a role in protecting water quality in this sensitive freshwater environment.

Laingsburg Lagoon discharges into the Shiawassee River watershed, which flows into the Saginaw River and then into Saginaw Bay, Lake Huron. This region is part of the Great Lakes Basin, a globally significant freshwater ecosystem that supports diverse aquatic life and provides drinking water for millions. The plant's secondary treatment helps reduce nutrient and organic pollutant loads, protecting downstream water quality in the Shiawassee River and Saginaw Bay.
