TRIMBLE WWTP - Secondary Treatment Plant in Trimble, Missouri

TRIMBLE WWTP is a municipal wastewater treatment facility located in Trimble, Missouri, a small community in Clinton County. The plant serves a population of 646 residents, reflecting its role as a local infrastructure asset for the town and surrounding area. The plant provides secondary treatment, which is the standard level required by the U.S. Clean Water Act for municipal wastewater facilities. Secondary treatment typically involves biological processes to remove organic matter and suspended solids. The plant has a designed capacity of 264.98 megaliters per year and treats an annual discharge volume of 189.27 megaliters, indicating operational capacity below design levels. The treated effluent is discharged into a local waterway, contributing to the watershed that ultimately drains into the Missouri River system. This river system supports diverse aquatic life and is an important resource for communities downstream. The plant's operations are subject to National Pollutant Discharge Elimination System (NPDES) permits, ensuring compliance with water quality standards.

The plant discharges into a tributary of the Missouri River, which flows into the Mississippi River and eventually the Gulf of Mexico. The local watershed supports agricultural and rural ecosystems, and the plant's secondary treatment helps protect downstream water quality by reducing organic pollutants and suspended solids before discharge.
