Mililani Mauka homeowners may install rain barrels without a Honolulu permit; small outdoor catchment up to 360 gallons is exempt under state plumbing code.
The City and County of Honolulu has no specific ordinance regulating residential rainwater harvesting in Mililani Mauka. Hawaii does not restrict rainwater collection, and the Board of Water Supply and Department of Health do not regulate individual residential catchment. Under the Hawaii Plumbing Code based on the 2018 UPC Chapter 16, outdoor irrigation catchment systems with storage up to 360 gallons do not need a permit. Mauka's plateau climate and moderate rainfall make rain barrels reasonably effective for garden irrigation. The Mililani Mauka Community Association design rules typically require barrels to be placed behind fences or screened from street view, and BWS has periodically offered rebates.
No ordinance penalties apply for compliant catchment. The Mauka HOA may require screening or deny front-yard placement under design guidelines.
