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.
