South Davis SD South Wastewater Treatment Plant, North Salt Lake, Utah

South Davis SD South is a wastewater treatment plant located in North Salt Lake, Utah, within Davis County. The facility serves a population of approximately 35,594, placing it in the medium agglomeration category under US regulatory frameworks. The plant is situated near the Legacy Parkway Trail, reflecting its integration into the local infrastructure. As a US-based plant, South Davis SD South 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 designed capacity is listed as 1.00, likely in million gallons per day or similar units, indicating a moderate-scale operation. The plant's discharge ultimately reaches the Great Salt Lake via local waterways, as the area drains into the lake's southern arm. The Great Salt Lake is a critical ecosystem for migratory birds and brine shrimp, making the plant's effluent quality important for maintaining the lake's salinity balance and ecological health. The plant's proximity to the lake (within 50 km) underscores its role in protecting this unique inland water body.

South Davis SD South discharges treated wastewater into the Jordan River watershed, which flows northward into the Great Salt Lake. The Great Salt Lake is a terminal saline lake and a vital habitat for millions of migratory birds, including eared grebes and Wilson's phalaropes, as well as brine shrimp that support the local ecosystem. The plant's operations are therefore significant for maintaining water quality in this sensitive inland basin, where nutrient loading and salinity levels must be carefully managed to prevent ecological disruption.
