Aurora Wastewater Treatment Plant, Utah | Small Community Secondary Treatment

The Aurora wastewater treatment plant is located in Aurora, Sevier County, Utah, United States. It serves a small community of approximately 1,016 residents, reflecting its role in managing municipal wastewater for a rural town. The plant operates under the regulatory framework of the US Clean Water Act, which requires secondary treatment for municipal facilities discharging to surface waters. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, meeting national effluent standards. The plant has a designed capacity of 499.67 megaliters and an annual discharge volume of 378.54 megaliters, indicating it operates below its full capacity. As a small facility in an inland setting, it contributes to local water quality management. The treated effluent is discharged into a receiving water body within the Sevier River basin, which ultimately drains to the Great Basin, a closed basin with no outlet to the ocean. This makes water quality protection particularly important for maintaining the ecological health of the basin's terminal lakes and wetlands.

The plant discharges into the Sevier River basin, part of the Great Basin, a closed drainage system that terminates in Sevier Lake, a shallow saline lake. The basin supports diverse aquatic life and migratory birds, and the plant's secondary treatment helps protect downstream water quality in this sensitive arid-region ecosystem. Proper nutrient removal is critical to prevent eutrophication in the terminal lake.
