The plant serves a small population of 814 residents and operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal facilities of this scale. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 454.25 units and a similar discharge volume, the facility is operating at full capacity. As a US plant, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the West Virginia Department of Environmental Protection, which set effluent limits to protect water quality. The treated effluent from GRANTSVILLE WWTP discharges into the Little Kanawha River basin, which flows into the Ohio River and ultimately the Mississippi River system. This watershed supports diverse aquatic life and provides drinking water for downstream communities. The plant's secondary treatment helps reduce nutrient and pollutant loads to the river, contributing to the ecological health of the region.

The Little Kanawha River watershed supports a variety of fish and wildlife, including species that rely on clean water for spawning and habitat. The plant's secondary treatment helps control organic pollution and nutrient loading, which is important for preventing eutrophication in downstream waters.
