Frequently Asked Questions

Can my city ignore the state drought rules?

No. State emergency conservation regulations are floors that every supplier and resident must follow. Cities may adopt stricter rules but cannot weaken state standards.

Are runoff and hose nozzles regulated statewide?

Yes. State permanent prohibitions require shutoff nozzles on hoses, ban irrigation runoff to streets, and prohibit washing hard surfaces with potable water.
