BERN WWTP - Secondary Treatment Plant in Bern, Kansas

BERN WWTP is a municipal wastewater treatment facility located in Bern, Nemaha County, Kansas, United States. The plant serves a small population of 200 residents, reflecting the rural character of the community. It is situated on Herold Street and operates under the regulatory framework of the US Clean Water Act, which governs wastewater discharges through the National Pollutant Discharge Elimination System (NPDES) permit program. The plant provides secondary treatment, a standard level required by the US EPA for most municipal facilities to reduce organic matter and suspended solids. With a designed capacity of 113.56 megaliters per year and an actual discharge volume of 75.71 megaliters, the plant operates below its capacity, indicating room for future growth or seasonal variability. Secondary treatment typically involves biological processes such as activated sludge or trickling filters. The treated effluent is discharged into a local water body, likely a stream or river within the Nemaha River basin, which ultimately drains into the Missouri River and then the Mississippi River. This watershed supports agricultural land use and provides habitat for aquatic species. The plant's discharge contributes to the overall water quality of the region, and compliance with permit limits is essential for protecting downstream ecosystems.

BERN WWTP discharges into a local watercourse within the Nemaha River basin, which flows into the Missouri River and eventually the Mississippi River. This watershed drains agricultural areas of northeastern Kansas and supports diverse aquatic life, including fish and macroinvertebrates. The plant's secondary treatment helps reduce nutrient loads, which is important for preventing eutrophication in downstream water bodies like the Gulf of Mexico, where nutrient pollution contributes to hypoxic zones.
