Salt Lake City Wastewater Treatment Plant, Utah | Serving 186,440 People

The Salt Lake City wastewater treatment plant is a major municipal facility located in Salt Lake City, Utah, along Riverview Avenue in the Rose Park neighborhood. Serving a population of 186,440, it is a large-scale treatment operation within the state's wastewater infrastructure. As a US facility of this size, the plant is subject to the Clean Water Act and operates under an EPA National Pollutant Discharge Elimination System (NPDES) permit issued by the Utah Division of Water Quality. For agglomerations serving over 100,000 people, secondary treatment is the minimum standard, with additional nutrient removal often required to protect sensitive water bodies. The plant's treated effluent discharges into the Jordan River, which flows northward into the Great Salt Lake, a terminal saline lake of significant ecological importance. The Great Salt Lake supports millions of migratory birds and unique aquatic life, making proper wastewater treatment critical to maintaining water quality and ecosystem health in this arid region.

The plant discharges into the Jordan River, which flows into the Great Salt Lake, a terminal lake with no outlet. The lake's hypersaline environment supports brine shrimp and migratory bird populations, making it ecologically sensitive. Nutrient loading from wastewater can contribute to algal blooms and oxygen depletion, so treatment standards are essential for preserving this unique ecosystem.
