IEUA Carbon Canyon WRF - Riverside, California Wastewater Treatment Plant

The IEUA Carbon Canyon Water Reclamation Facility (WRF) is a major wastewater treatment plant located in Riverside, California, within the Inland Empire region. Serving a population of around 115,000, it is part of the Inland Empire Utilities Agency's (IEUA) regional water infrastructure. The plant plays a key role in managing wastewater for the growing communities of Riverside County. As a US facility of this scale, the plant operates under the Clean Water Act and is subject to National Pollutant Discharge Elimination System (NPDES) permits issued by the California State Water Resources Control Board. For a plant serving over 100,000 people, secondary treatment is the minimum standard, with potential for advanced treatment to meet water quality goals. The plant's treatment processes are designed to protect public health and the environment. The treated effluent from the Carbon Canyon WRF is discharged into the Santa Ana River, which flows through Southern California to the Pacific Ocean. The Santa Ana River is a critical water source for the region and supports diverse aquatic habitats. The plant's operations are essential for maintaining water quality in this arid watershed, where water reuse and conservation are increasingly important.

The plant discharges into the Santa Ana River, which flows through Riverside and Orange Counties before reaching the Pacific Ocean near Huntington Beach. The river supports a variety of wildlife, including migratory birds and fish species, and its water is used for groundwater recharge and irrigation. The arid climate of Southern California makes water quality management crucial for ecosystem health and water supply sustainability.
