Clear Creek WWTF is a wastewater treatment facility located in Redding, California, serving a population of around 158,803. The plant is situated inland, more than 50 km from the coast, and plays a key role in managing wastewater for the city and surrounding communities. As a large agglomeration serving over 150,000 people, the plant operates under the U. S. Clean Water Act, which requires secondary treatment as a minimum standard for municipal wastewater facilities. The National Pollutant Discharge Elimination System (NPDES) permit program, administered by the California State Water Resources Control Board, governs discharge limits and monitoring requirements to protect water quality. The plant's treated effluent is discharged into local waterways that ultimately drain into the Sacramento River system, which flows through the Central Valley to the Sacramento-San Joaquin Delta and San Francisco Bay. This watershed supports diverse aquatic life and provides water for agriculture and communities downstream.

Clear Creek WWTF discharges into the Sacramento River basin, which flows through Northern California to the Sacramento-San Joaquin Delta and San Francisco Bay. The receiving waters support important fish species such as Chinook salmon and steelhead trout, and the delta is a critical ecological and hydrological hub for the region.
