The Sanitation Division has two Operations Sections:

  • Collections Section
  • Treatment Section

Collections Section - Sewer System

The Collections Section operates, maintains, and monitors the sewer system to assure sewage is safely and properly conveyed from nearly 40,000 lateral connections to the City's Water Quality Control Plant.

Sewer System Management Plans are state-mandated requirements for California’s public collection system agencies that own or operate sanitary sewer systems greater than one mile in length. The purpose of these plans is to:

  • Facilitate proper funding and management of sanitary sewer systems.
  • Reduce sanitary sewer overflows.
  • Protect public health and the environment.
  • Improve the overall maintenance and operation of sewer systems and sewage lift stations.

Please download the City of Simi Valley 2014 Sewer System Management Plan  and the City of Simi Valley Sewer Lateral Policy for additional information.
 

Treatment Section - Water Quality Control Plant

The Treatment Section operates, maintains, and monitors the Water Quality Control Plant.

The City of Simi Valley’s Water Quality Control Plant treats approximately 10 million gallons of wastewater each day to protect public health and safety and to comply with State and Federal regulations.  The wastewater comes from a variety of sources, including discharges from local businesses and industries, with the majority of discharge coming from residential properties. 

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.

To learn how the City cleans water take a virtual tour of the Water Quality Control Plant.
