Hayward Recycled Water Project

The City of Hayward is implementing a Recycled Water Project to provide recycled water for irrigation of parks, schools, roadway medians, and landscaped areas around commercial and industrial buildings.

Community Benefits

Every gallon of water that is recycled conserves a gallon of drinking water and reduces the volume of wastewater that is discharged to San Francisco Bay. The following are the beneficial uses of recycled water:

  • Creates a locally sustainable water supply
  • Conserves drinking water supplies
  • Improves water supply reliability during droughts
  • Reduces treated wastewater discharges to the San Francisco Bay
  • Keeps Hayward landscaping green 
  • Provides customers with a drought-proof supply

Safe, Drought-Proof, High-Quality Water

Recycled water will be produced from wastewater that is collected from the homes and businesses within Hayward and treated at the City’s Water Pollution Control Facility. Recycled water provided to customers will be tertiary-treated water that has undergone the advanced treatment processes of filtration and disinfection to produce high quality recycled water that is safe for reuse.

In California, the State regulates the production and use of recycled water and has adopted strict public health and safety regulations to protect the public from any potential risks associated with recycled water. Recycled water is routinely tested to ensure compliance with stringent water quality standards and can only be delivered to customers if it meets all requirements.

Project Facilities

Phase I of the Recycled Water Project consists of a one million-gallon tank, a pump station, and a 0.5 mgd membrane treatment plant at the City’s Water Pollution Control Facility, as well as approximately nine miles of distribution pipelines and customer connections to deliver an estimated 290 acre-feet per year, or about 260,000 gallons per day, of recycled water. 

The water will be used for irrigation of parks, schools, and landscaped areas around commercial and industrial buildings.  Phase I will focus on supplying recycled water for irrigation uses.  The City is still evaluating the feasibility of expanding the use of recycled water to serve industrial users in the future.

Phase 1 Service Area

Construction of recycled water pipelines to serve customers in the Phase 1 service area began in June 2018 and was completed in the spring of 2019. The tank and pump station construction was completed in November 2019, and the treatment plant is anticipated to be completed in January 2020. The customer onsite retrifit construction is scheduled for completion by spring of 2020. Deliveries to the Phase 1 customers are anticipated to begin in mid-2020.
