Delleker WWTF - Secondary Wastewater Treatment in Plumas County, California

Delleker WWTF (Wastewater Treatment Facility) is located in Plumas County, California, United States. This plant serves a small population of 425 residents, providing secondary treatment for municipal wastewater. The facility is situated inland, far from coastal areas, and operates under the regulatory framework of the US Clean Water Act. The plant's treatment process is secondary, which is typical for small communities in the United States. With a designed capacity of 378.54 million gallons per year and an actual discharge volume of 124.92 million gallons, the facility operates well below its capacity. This suggests adequate infrastructure for current demand. As a US plant, it is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the California State Water Resources Control Board. The treated effluent from Delleker WWTF is discharged into local waterways that ultimately drain into the Sacramento River system and then to the San Francisco Bay and Pacific Ocean. The plant plays a crucial role in protecting water quality in the Sierra Nevada region, supporting downstream aquatic ecosystems and recreational uses.

Delleker WWTF discharges into local streams that flow into the Feather River, a major tributary of the Sacramento River. The Sacramento River system drains into the Sacramento-San Joaquin Delta and San Francisco Bay, ultimately reaching the Pacific Ocean. This watershed supports diverse aquatic life, including salmon and steelhead trout, and provides water for agriculture and urban areas. The plant's secondary treatment helps reduce nutrient and pathogen loads, protecting downstream water quality in this ecologically sensitive region.
