Water restrictions in Castro Valley, CA — also called the watering schedule, outdoor irrigation rules, or drought ordinance — set which days and hours you can run sprinklers or irrigation.
Castro Valley is served by East Bay Municipal Utility District (EBMUD). EBMUD's Water Conservation Regulation 14 permanently bans irrigation runoff, hosing down hardscape, and using non-recirculating water features. Drought stages add stricter watering days.
EBMUD's Drought Management Program and Regulation No. 14 set permanent water-use rules for Castro Valley: no irrigation runoff onto sidewalks or streets, no watering within 48 hours of measurable rain, no washing down driveways/patios with potable water, no non-recirculating decorative fountains, and restaurants serve water only on request. During declared drought stages (currently Stage 1 as of 2024 review), additional limits include watering before 9 a.m. or after 6 p.m., max 3 watering days/week. Castro Valley's separate sewer wholesaler is Castro Valley Sanitary District.
