The ordinance, as written (Hawaiʻi County) — Subdivisions
A copy, taken August 21, 2026. The version published by Hawaiʻi County is the one that governs, and it may have changed since. Check it before relying on anything here.
Where public sewer service is accessible to any subdivision, the subdivider shall install all necessary sewage works to serve all lots. All new sewers and connections shall be properly designed and connected. For areas planned for sewers within the ten years after May 22, 1989, developers are required to install interceptor, household, and collection sewers, even if they will not be used until the area is sewered. Where public sewers are not accessible or dry sewers planned, the requirements or interim requirements for proper disposal of sanitary sewage for the subdivision shall be determined by the State department of health and the director.
