Riverside County retail water agencies set day-of-week irrigation schedules under California state framework SB 606 and AB 1668, with Coachella Valley Water District and Western Municipal Water District enforcing local rules.
California requires water suppliers to declare drought stages with mandatory outdoor watering schedules. In Riverside County, retail providers including Coachella Valley Water District, Desert Water Agency, Western MWD, Eastern MWD, and Rancho California Water District set assigned watering days, prohibit runoff, and ban midday irrigation between 10 a.m. and 6 p.m. Spray irrigation within 48 hours after measurable rainfall is prohibited. Single-pass cooling systems are banned. Hand-watering with shutoff nozzles and drip irrigation are typically allowed any day.
Agencies issue warning letters then escalating fines, often 100 dollars first, 250 dollars second, and 500 dollars or more thereafter; water flow restrictors may also be installed.
