BASIN WandS DISTRICT Wastewater Treatment Plant, Basin, Montana

BASIN WandS DISTRICT is a wastewater treatment plant located in Basin, Jefferson County, Montana, United States. The facility serves a small population of 210 residents, reflecting its role in a rural community. The plant is situated on Frontage Road 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 that removes biodegradable organic matter and suspended solids. With a designed capacity of 170.34 volume units and a current discharge volume of 128.70 volume units, the facility operates below its capacity. The treated effluent is discharged into a local water body, likely a stream or river within the Missouri River basin, as Basin lies in the Jefferson River watershed. The plant's inland location, over 50 km from the coast, reduces direct marine impact. The surrounding environment includes mountainous terrain and supports aquatic life in the region's cold-water streams.

The plant discharges into a receiving water body within the Jefferson River watershed, which flows into the Missouri River and ultimately the Mississippi River and Gulf of Mexico. The local watershed supports diverse aquatic species, including trout and other cold-water fish. The plant's secondary treatment helps protect downstream water quality in this ecologically sensitive region.
