ROBERTS CARBON CO COMM Wastewater Treatment Plant, Roberts, Montana

ROBERTS CARBON CO COMM is a municipal wastewater treatment plant located in Roberts, Carbon County, Montana. The facility serves a small population of around 250 residents and 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 biological process that removes organic matter and suspended solids. With a designed capacity of 189.27 m³/day and an actual discharge volume of 707.87 m³/day, the facility is operating above its nominal capacity, indicating potential stress on the treatment system. The treated effluent is discharged to a local water body, likely a tributary of the Clarks Fork Yellowstone River, which flows into the Yellowstone River and ultimately the Missouri River and Mississippi River. The plant's operations are important for protecting water quality in this rural watershed, which supports aquatic life and agricultural uses.

The plant discharges into a local stream within the Clarks Fork Yellowstone River basin, part of the larger Yellowstone River watershed. This region is characterized by semi-arid climate and agricultural land use. The receiving waters support fish species such as trout and provide irrigation for local farms. Downstream, the Yellowstone River flows into the Missouri River, a major tributary of the Mississippi River, eventually reaching the Gulf of Mexico.
