Recycled Water

To meet future water demands while reducing dependence on imported water, the City of San Diego built the North City Water Reclamation Plant and the South Bay Water Reclamation Plant. These plants treat wastewater to a level that is approved for irrigation, manufacturing and other non-drinking, or non-potable purposes. Recycled water gives San Diego a dependable, year-round and locally controlled water resource.

Recycled Water Service Interruption

A three-day planned shutdown of the North City Water Reclamation Plant is scheduled for Feb. 12-14. The plant will shut down Monday at 6 a.m. and be back in service Wednesday evening. The shutdown is due to a scheduled repair of a pipe inside the facility. NCWRP will not be producing or pumping any water during this time. PUD will make all efforts to complete the work as scheduled and will notify all customers once the facility is back in service.

Rules and Regulations

The California State Water Resources Control Board sets the standards for levels of treatment and types of uses for recycled water. These standards are included in the California Code of Regulations, Title 22.

There are extensive PDF icon rules and regulations regarding the use of recycled water in the City of San Diego. These include making sure all pipes, sprinkler heads, meter boxes, and other irrigation equipment are properly marked or color-coded purple and properly labeled with signage to distinguish them from potable water supplies. The Public Utilities Department will work with customers to ensure they are in compliance with all regulations.

Approved uses of recycled water include the irrigation of:

  • Parks
  • Playgrounds
  • School-yards
  • Residential landscaping
  • Common areas
  • Nurseries
  • Freeway landscaping
  • Golf courses

Additional approved uses for recycled water include recreational water bodies including fishing/boating and source water for industrial processing, commercial laundries and soil compaction. Recycled water is also available for construction purposes under the Recycled Water Tanker Truck Program (see below).

Recycled Water Tanker Truck Program

State of California health officials allow local recycled water tanker truck programs for construction purposes only. The City has one operational tanker truck filling station in South Bay which is currently used by SDG&E. The City is exploring options to add additional commercial filling stations in the northern service area.
