Sanitation Services Division
To protect public health and safety, and to comply with state and federal regulations, the City of Simi Valley’s Water Quality Control Plant treats approximately 10 million gallons of wastewater each day. The wastewater comes from a variety of sources, including discharges from local businesses and industries, with a majority of discharge coming from residential. The Water Quality Control Plant (Treatment Plant) is located on 33 acres at the western end of Simi Valley. The Treatment Plant is an activated sludge plant using the latest methods for biological nutrient removal. After meeting stringent state permit requirements, treated water is discharged to the Arroyo Simi. The entire treatment system is continuously monitored via a state of the art SCADA computer system. Prior to discharge, a portion of the effluent water is reclaimed and used for dust control and irrigation at the Simi Valley Landfill. The Sanitation Division is an enterprise-funded activity. It relies upon user fees (not tax funds) to pay for the approximate $12.5 million annual expense. The customers are served with reliable and environmentally advanced services for a cost less than the regional median cost for such services.
