San Jose FAQ
Can I water my lawn at any time?
No. Year-round, irrigation between 10 a.m. and 8 p.m. is prohibited because of evaporation losses. Drip irrigation and hand-held bucket use can be allowed at limited times during drought stages.
How do I report water waste?
Call San Jose 311 or use the Valley Water Water Waste Reporter online (valleywater.org). Photos help; investigators issue warnings, then citations, often within 7–10 business days of a complaint.
Santa Clara FAQ
Which days can I water my lawn?
Days are typically assigned by street address, with even numbers on one set of days and odd on another. Check your specific retailer (San Jose Water, City of Santa Clara, Sunnyvale Water) for the current schedule and any drought-stage modifications.
Do drip irrigation and hand watering have the same limits?
Drip and hand-held hoses with positive shutoff nozzles are usually allowed any day for short periods, but still must avoid daytime hours when shortage stages are declared and runoff remains prohibited.
