Jansen WWTP - Secondary Treatment Facility in Jansen, Nebraska

Jansen WWTP is a municipal wastewater treatment plant located in Jansen, Jefferson County, Nebraska. It serves a small population of 143 residents, reflecting the rural character of the area. The facility is situated on Meridan Street and provides essential wastewater services to the local community. The plant employs secondary treatment, which is the standard biological treatment process required by the US Clean Water Act for municipal facilities. With a designed capacity of 64.35 (likely thousand gallons per day or similar unit), the plant operates at full capacity based on reported discharge volume. As a small facility, it falls under state-level NPDES permitting overseen by the Nebraska Department of Environment and Energy. The treated effluent is discharged into nearby surface waters, contributing to the local watershed that ultimately drains into the Missouri River basin. This small plant plays a role in protecting downstream water quality in the Great Plains region, where agricultural runoff and municipal discharges are key water quality concerns.

The plant discharges into local streams that flow into the Big Blue River basin, a tributary of the Missouri River. This watershed supports agricultural irrigation and provides habitat for fish and wildlife species typical of the Great Plains. The Missouri River eventually joins the Mississippi River, draining into the Gulf of Mexico. Protecting water quality in this basin is important for maintaining aquatic ecosystems and downstream uses.
