Water restrictions in Honolulu County, HI — also called the watering schedule, outdoor irrigation rules, or drought ordinance — set which days and hours you can run sprinklers or irrigation.
Honolulu County authorizes water conservation under ROH Chapter 30, Section 30-2.3, while day-of-week irrigation and stage-based shortage rules are issued by the Honolulu Board of Water Supply separately for the entire island.
ROH Sec. 30-2.3 addresses water conservation, use restrictions, allocations, pricing, and use of non-potable sources for irrigation. Operational shortage rules (stages 1 through 4, odd/even watering days, time-of-day outdoor use limits) are administered by the Honolulu Board of Water Supply under its own rulemaking authority, not codified in the ROH. Countywide drought pressure historically affects leeward Oahu and Central Oahu aquifer drawdown. Restrictions can be activated island-wide or tailored to specific service areas when reservoir storage drops.
BWS may issue warnings, administrative fines, and ultimately disconnect service for repeat violations of shortage rules; code violations under Chapter 30 carry separate civil penalties.
