Mililani Town irrigation follows Board of Water Supply drought schedules; ROH Sec. 30-2.3 frames the policy and Central Oahu's aquifer is heavily watched.
Mililani Town sits atop the Central Oahu aquifer and uses significant summer irrigation across Mililani Mauka's HOA-managed landscaping and large private yards. ROH Chapter 30, Sec. 30-2.3 sets the water management framework, including conservation strategies, allocations, and non-potable use. Operational drought stages 1 through 4, day-of-week watering schedules, and hard-surface washing restrictions are issued by the Honolulu Board of Water Supply rather than codified in ROH. Mililani's mostly suburban grass lawns and HOA common areas can consume a large share of potable supply, so BWS shortage enforcement tends to focus on automated irrigation controllers that water outside the allowed time windows.
BWS warns first-time violators and may issue fines or install flow restrictors at the meter for repeat shortage-stage violations.
