GRANTSVILLE Wastewater Treatment Plant, Grantsville, Utah

The GRANTSVILLE wastewater treatment plant is located in Grantsville, Tooele County, Utah, United States. It serves a population of approximately 8,893 residents, making it a small to medium-sized municipal facility. The plant is situated inland, about 50 kilometers from the coast of the Great Salt Lake. As a U.S. facility, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the Utah Department of Environmental Quality. For plants of this scale, secondary treatment is typically required, and the designed capacity of 1.00 million gallons per day suggests the plant is sized to handle the community's wastewater flows. The treated effluent from the plant is discharged into local waterways that ultimately drain into the Great Salt Lake, a unique hypersaline lake and a critical habitat for migratory birds. The plant plays a key role in protecting the water quality of the surrounding watershed and the downstream environment.

The plant discharges into the drainage basin of the Great Salt Lake, a terminal lake with no outlet. The lake is a vital ecosystem for millions of migratory birds and supports brine shrimp and other salt-tolerant species. Protecting water quality in this watershed is essential to maintain the ecological balance of the lake and its surrounding wetlands.
