Nyeland Acres Wastewater Treatment Facility (WWTF) - Niland, California

Nyeland Acres Wastewater Treatment Facility (WWTF) is located in Niland, Imperial County, California, serving a small community of approximately 1,052 residents. The plant provides secondary treatment, which is the standard for municipal wastewater in the United States under the Clean Water Act, ensuring removal of biodegradable organic matter and suspended solids. With a designed capacity of 1,211.33 units and an average discharge volume of 643.52 units, the facility operates within its capacity. As a US plant, it is regulated under the National Pollutant Discharge Elimination System (NPDES) permit program, administered by the California State Water Resources Control Board, which sets effluent limits to protect water quality. The plant's treated effluent is discharged into the Salton Sea watershed, a large saline lake in Southern California that serves as a critical habitat for migratory birds and aquatic species. The region's arid climate and agricultural runoff make water quality management essential for the ecological health of the Salton Sea and downstream Colorado River delta.

The plant discharges into the Salton Sea basin, a terminal saline lake that receives agricultural and municipal runoff from the Imperial Valley. The Salton Sea is a vital stopover for migratory birds along the Pacific Flyway and supports unique aquatic life. Its hypersaline conditions and fluctuating water levels pose ecological challenges, making effective wastewater treatment crucial for maintaining water quality in this sensitive desert ecosystem.
