RUDYARD WWTP - Hill County, Montana Wastewater Treatment Plant

RUDYARD WWTP is a municipal wastewater treatment facility located in Hill County, Montana, United States. The plant serves a small population of 281 residents, reflecting its role in a rural community. It operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal discharges. The plant provides secondary treatment, a standard level that removes biodegradable organic matter and suspended solids. With a designed capacity of 75.71 units and an average discharge volume of 71.92 units, the facility operates near its capacity. Secondary treatment typically involves biological processes such as activated sludge or trickling filters. The treated effluent is discharged into a local water body, contributing to the watershed of the Milk River basin, which eventually drains into the Missouri River system. This region supports agricultural activities and diverse aquatic life, making proper wastewater treatment essential for protecting downstream water quality and ecosystem health.

The plant discharges into a local watercourse within the Milk River basin, which flows into the Missouri River and ultimately the Mississippi River system. The surrounding area is primarily agricultural, and the plant's effluent must meet water quality standards to protect downstream aquatic habitats and irrigation uses. The region's semi-arid climate means that maintaining water quality in receiving streams is critical for both ecological balance and human use.
