Rockville STP - Secondary Wastewater Treatment in Bates County, Missouri

Rockville STP is a municipal wastewater treatment facility located in Bates County, Missouri, United States. The plant serves a small population of 166 residents, reflecting its role in a rural community. As a secondary treatment plant, it provides biological treatment to reduce organic matter and suspended solids before discharge. The plant's designed capacity is 94.64 units, with an actual discharge volume of 71.92 units, indicating operational headroom. Under the U.S. Clean Water Act, such facilities operate under National Pollutant Discharge Elimination System (NPDES) permits issued by the Missouri Department of Natural Resources, which set effluent limits to protect water quality. The treated effluent from Rockville STP likely discharges into a local stream or river within the Osage River basin, which ultimately flows into the Missouri River and then the Mississippi River. The plant's inland location and small scale minimize its impact on downstream aquatic ecosystems, though proper nutrient management remains important for preventing eutrophication in receiving waters.

The plant discharges into a local watercourse within the Osage River watershed, which drains into the Missouri River and eventually the Mississippi River. This inland system supports diverse aquatic life and is used for recreation and agriculture. The secondary treatment process reduces organic pollutants, but nutrient removal may be limited, potentially contributing to downstream algal blooms in sensitive areas.
