White Sulphur Springs STP - Secondary Wastewater Treatment in Meagher County, Montana

WHITE SULPHUR SPRINGS STP is a municipal wastewater treatment facility located on Cemetery Road in Meagher County, Montana. Serving a population of 939, the plant provides secondary treatment to meet state and federal water quality standards under the U.S. Clean Water Act. The plant has a designed capacity of 378.54 megaliters per year and currently treats a discharge volume of 109.78 megaliters annually. As a secondary treatment facility, it uses biological processes to reduce organic pollutants and suspended solids before discharge. The treated effluent is released into local streams that drain into the Missouri River watershed, ultimately reaching the Mississippi River and the Gulf of Mexico. The plant plays a key role in protecting downstream aquatic ecosystems and maintaining water quality in this rural Montana region.

The plant discharges into tributaries of the Missouri River, which flows through the Great Plains to the Mississippi River and the Gulf of Mexico. The local watershed supports diverse aquatic life, including native fish species, and the plant's secondary treatment helps reduce nutrient loading that could otherwise contribute to downstream algal blooms.
