Water restrictions in Kailua, HI — also called the watering schedule, outdoor irrigation rules, or drought ordinance — set which days and hours you can run sprinklers or irrigation.
Kailua irrigation users along Kailua Beach and Lanikai must follow Board of Water Supply drought stages; ROH Chapter 30 sets broader management policy.
Kailua's lush residential landscaping and large yards in Maunawili and Coconut Grove drive significant summer irrigation demand. ROH Chapter 30, Sec. 30-2.3 establishes the city's water management framework, including conservation policy, allocations, and non-potable irrigation priorities. Operational drought responses such as stage 1 through 4 day-of-week watering schedules, spray restrictions, and sprinkler time windows are issued by the Honolulu Board of Water Supply under separate regulatory authority rather than codified in ROH. Kailua's windward aquifer recharge is strong, but drought declarations still apply islandwide, and beachfront turf irrigation is a common focus of enforcement.
BWS warns first-time violators and may issue fines or service-flow restrictions for repeat offenders during declared shortage stages.
