MAGNA WID Wastewater Treatment Plant, Magna, Utah

MAGNA WID is a municipal wastewater treatment plant located at 7755 West in Magna, Salt Lake County, Utah. The plant serves an estimated population of 26,505 residents, placing it in the medium-agglomeration category for US facilities. Its designed capacity is 1.00 million gallons per day, reflecting the scale of treatment needed for this suburban community near the Great Salt Lake. As a US-based plant, MAGNA WID operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permitting, typically administered by the Utah Department of Environmental Quality. The plant's treated effluent ultimately discharges into the Great Salt Lake watershed, a terminal saline lake that supports unique aquatic ecosystems and migratory bird populations. The receiving water body is part of the larger Great Basin drainage, where water quality management is critical due to the lake's endorheic nature and sensitivity to nutrient loading.

The plant's discharge enters the Great Salt Lake watershed, a terminal basin with no outlet to the sea. The lake's high salinity and fluctuating water levels create a unique environment for brine shrimp and migratory birds. Downstream, the lake supports a critical ecosystem along the Pacific Flyway, making nutrient and pollutant control essential for maintaining ecological balance.
