Knights Landing WWTF - Secondary Wastewater Treatment in Knights Landing, California

Knights Landing Wastewater Treatment Facility (WWTF) is located in Knights Landing, Yolo County, California, United States. The plant serves a small population of 663 residents, providing secondary treatment for municipal wastewater. The facility operates under the U.S. Clean Water Act, which requires secondary treatment for municipal wastewater plants. With a designed capacity of 416.39 megaliters and an annual discharge volume of 227.13 megaliters, the plant is operating below its capacity. The treated effluent is discharged into local waterways that eventually drain into the Sacramento River system, which flows into the Sacramento-San Joaquin Delta and ultimately the Pacific Ocean. The plant plays a role in protecting the water quality of the region's aquatic ecosystems.

The plant discharges into the Sacramento River basin, which flows through the Sacramento-San Joaquin Delta, a critical estuarine ecosystem supporting diverse fish and wildlife. The delta is a major water source for California and provides habitat for migratory birds and endangered species. Downstream, the waters reach the Pacific Ocean via San Francisco Bay.
