Regional Map of Recycled Water Pipeline

The City of Palo Alto’s Recycled Water Program began in the early 1980s. The City’s Recycled Water Program conserves drinking water by providing an alternative water supply for irrigation and other non-potable uses. The City’s Regional Water Quality Control Plant (RWQCP) produces recycled water for use in the East Palo Alto Sanitary District, Los Altos, Los Altos Hills, Mountain View, Palo Alto, and Stanford University. The City of Palo Alto's recycled water pipeline distributes recycled water from the RWQCP to the City of Mountain View and a few City of Palo Alto facilities (including the Municipal Golf Course, Municipal Services Center, Animal Services Facility, and Greer Park). Recycled water can be picked up  at the RWQCP by residents and businesses for approved uses. Learn more about the City’s recycled water and other non-potable water sources.

Currently, residents and businesses cannot connect to the recycled water pipeline.  The City of Palo Alto evaluated how to offer this service in the future under the Northwest County Recycled Water Strategic Plan.  The Northwest County Recycled Water Strategic Plan is a collaboration between the City of Palo Alto RWQCP and the Santa Clara Valley Water District that seeks to identify the most appropriate ways to expand the City of Palo Alto’s Recycled Water Program.  The plan evaluated the potential expansion of the recycled water pipeline to the Stanford Research Park area as well as potable water reuse. Refer to below sections for project task updates.  The Northwest County Recycled Water Strategic Plan project began in December 2016 and is scheduled for completion in 2020.
