DRUMMOND WWTP - Bradman, Montana Wastewater Treatment Plant

DRUMMOND WWTP is a municipal wastewater treatment plant located in Bradman, Granite County, Montana, United States. The facility serves a small population of approximately 230 residents, reflecting its role in a rural community. The plant is situated near Interstate 90 and US Highway 12, providing access to the surrounding area. The plant provides secondary treatment, which is the standard level required under the US Clean Water Act for municipal wastewater facilities. With a designed capacity of 151.42 cubic meters per day and an average discharge volume of 75.71 cubic meters per day, the plant operates well within its capacity. The US Environmental Protection Agency (EPA) and the Montana Department of Environmental Quality oversee permitting and compliance under the National Pollutant Discharge Elimination System (NPDES). The treated effluent is discharged into local waterways that ultimately drain into the Clark Fork River basin, a major tributary of the Columbia River system. This watershed supports diverse aquatic life and is important for regional water quality. The plant's inland location, over 50 kilometers from the coast, reduces direct marine impact.

The treated effluent from DRUMMOND WWTP enters local streams that flow into the Clark Fork River, which joins the Pend Oreille River and eventually reaches the Columbia River and the Pacific Ocean. This watershed is ecologically sensitive, supporting native fish species such as bull trout and westslope cutthroat trout. The plant's secondary treatment helps protect these downstream habitats from nutrient pollution and organic loading.
