Project Partners: City of Victorville and Woodard & Curran (which operates the Victorville Industrial Wastewater Treatment Plant (IWWTP))
Facility: Southern California Logistics Airport (SCLA) Industrial Wastewater Treatment Plant, which includes the Victorville Industrial Wastewater Treatment Plant (IWWTP), located at the former George Air Force Base in Victorville
Established: IWWTP was first built in 2012
Average Daily Capacity: The SCLA Industrial Wastewater Treatment Plant capacity is 2.5 mgd: 1 mgd industrial and 1.5 mgd sanitary. The IWWTP is designed to treat a combined waste stream of industrial and domestic wastewater with a capacity of 2.5 mgd.
Permit Violations: IWWTP has not had any permit violations in the past three years.

The City of Victorville’s SCLA Industrial Wastewater Treatment Plant is a Class IV tertiary treatment facility designed to treat high-strength wastewater from industrial manufacturing processes alongside normal-strength wastewater, utilizing a combination of anaerobic and aerobic treatment technologies.
Industrial flow undergoes anaerobic treatment in an upflow anaerobic sludge blanket (UASB) to reduce biochemical oxygen demand by 85% before being added to sanitary flow. Combined flows undergo activated sludge treatment and clarification in a membrane bioreactor (MBR), along with anoxic tanks for the removal of nutrients. MBR permeate is treated by UV disinfection prior to discharge to meet requirements for effluent disposal under California Title 22.
In 2018, the Operations staff developed and incorporated a cyclical aeration schedule to maintain the same concentration of dissolved oxygen, with reduced blower runtime, while still promoting nitrification.
In 2022, the facility’s membrane bioreactors were retrofitted with the latest Leap Air technology. This reduced the amount of aeration blowers needed to provide the same amount of scouring energy, thus saving energy and dollars to operate the system. The latest version of MBRs also provides higher throughput capacity within a smaller footprint, allowing for more expansion in the same area.
In 2023, IWWTP changed from traditional metal halide lighting to LED lighting throughout the facility, saving the City a substantial amount of money spent on electricity.
“IWWTP monitors water quality parameters with accurate, high-quality, low-maintenance instrumentation. This allows for staff to focus on key performance indicators such as effluent quality, nutrient removal, removal efficiencies, and sludge production. These indicators are incorporated into process control methods that enable reliable process and effluent monitoring, ensuring compliance with stringent effluent quality parameters.”
“The City of Victorville (City) owns and operates a sewer collection system that collects wastewater from approximately 29,000 connections and transports it either to the City’s Industrial Wastewater Treatment Plant (IWWTP) or the Victor Valley Wastewater Reclamation Authority (VVWRA) for treatment.”
