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, as well as for industrial purposes.

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.

  • 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 consists of constructing a one million-gallon tank and pump station at the City’s Water Pollution Control Facility and installing approximately ten 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.

Estimated Timeline

An environmental review was completed in 2014 that included preparation and adoption of an Initial Study/Mitigated Negative Declaration. The City is currently in final design of Phase I and expects to initiate construction on the tank, pump station, and distribution system by the end of 2017.  The City has initiated discussions with potential recycled water customers and anticipates designing and installing customer retrofits in 2018.  The project is scheduled to begin recycled water deliveries in early 2019.
