Monterey WWTP - Secondary Wastewater Treatment in Monterey, Indiana

Monterey WWTP is a municipal wastewater treatment plant located in Monterey, Pulaski County, Indiana. It serves a small population of 255 residents, reflecting the rural character of the area. The plant is situated in the Midwestern United States, where wastewater infrastructure supports dispersed communities. The plant provides secondary treatment, a standard level required by the US Clean Water Act for municipal facilities. With a designed capacity of 117.35 units and a discharge volume matching that figure, the plant operates at full capacity. As a small facility, it is subject to EPA NPDES permitting administered by the Indiana Department of Environmental Management, which sets effluent limits to protect water quality. The treated effluent is discharged into a local water body that ultimately drains into the Mississippi River Basin. The plant plays a role in safeguarding downstream ecosystems, including the Tippecanoe River and the Wabash River, which support diverse aquatic life and recreational uses.

The plant discharges into a tributary of the Tippecanoe River, which flows into the Wabash River, a major tributary of the Ohio River and ultimately the Mississippi River. This watershed supports diverse aquatic species and provides habitat for migratory fish. The region's agricultural land use means the plant's nutrient removal helps prevent eutrophication in downstream waters.
