Notice: The Residential Recycled Water program is currently suspended for the duration of the rainy season.  Please check back in Spring of 2020 for information on training sessions and program hours of operation.  

In the spring and summer months, the City of San Carlos offers free recycled water to San Carlos residents for use in landscape irrigation.  Water recycling is a safe way to preserve our natural water resources, reducing the amount of fresh water (potable water) required for non-drinking uses and reserving the purest sources of water for the highest use - public drinking water. 

Recycled water is produced from wastewater that undergoes a high level of additional treatment, including disinfection, transforming it to a quality approved for use in landscaping.  In this set of Guidelines, “Recycled Water” as defined by the Division of Drinking Water (DDW) of the State Water Resources Control Board (SWRCB) is disinfected tertiary recycled water.                                                               

Recycled water is not subject to water use restrictions, and provides a drought-resistant and environmentally friendly way to keep your yard green. 

Residents must attend a mandatory brief training session to participate in the Recycled Water Program.  In the spring and summertime, training is offered at 8:00 a.m. and 10:00 a.m., Monday through Saturday, at the City of San Carlos Corporate Yard located at 1000 Bransten Road.  After receiving the training, residents can obtain recycled water Monday through Saturday from 8:00 a.m. to 12:00 p.m.  To learn more about recycled water, please call (650) 802-4145 or email
