Recycled Water

On April 20th, 2015, the City of Palo Alto released a Draft Environmental Impact Report (DEIR) for the Palo Alto Recycled Water Project. The project would deliver recycled water produced by Palo Alto’s Regional Water Quality Control Plant (RWQCP) to parks and commercial customers in and near the Stanford Research Park. The objectives are to conserve potable water by providing an alternative supply of high quality recycled water for irrigation and other non-potable uses and to increase resiliency of the overall system in times of drought and emergencies. In the long term, the pipeline system could also deliver water to groundwater recharge injection well sites, if needed.  The proposed pipeline system is shown below in red:

Public meetings to discuss the project will be held in May. Public comments about the project will be accepted between April 20th and June 4th. 

Meeting location: Mitchell Park Community Center (Adobe South Meeting Room),
3700 Middlefield Road, Palo Alto, CA 94303.

Project Funding 






Palo Alto’s Water Reuse Program began in the early 1980s. In what is now considered Phase 1 of the RWQCP recycled water system the initial delivery of recycled water to Shoreline Golf Links was later expanded to include the Palo Alto Municipal Golf Course, Greer Park, and the Emily Renzel Marsh.

Palo Alto then completed a Water Reclamation Master Plan in 1992.  The Palo Alto Recycled Water Project is considered Phase 2 of this Master Plan and comes at a time when new high quality water sources must be identified to offset potable water use for irrigation at public parks and business campuses. 

As part of California Environmental Quality Act (CEQA) requirements, an Initial Study and Draft Mitigated Negative Declaration was issued in March 2009 which contained a checklist evaluating impacts on the environment associated with construction and operation of the project. Comments were received during the 30-day public comment period. The City completed a Response to Comments document in May 2009. Due to public concerns regarding the irrigation of redwood trees with recycled water, the City did not take pursue the project at that time. Since then, steps have been taken to reduce salinity and drought conditions have made consideration of the project urgent.
