East Honolulu's coastal drainages to Maunalua Bay and Hawaii Kai waterways fall under ROH Chapter 43, Article 11 stormwater rules prohibiting non-stormwater discharges to the city's MS4 system.
Sec. 43-11.12 governs connections to the city separate storm sewer, and Sec. 43-11.22 prohibits discharging effluent other than stormwater into the MS4. Common non-allowed discharges include soapy wash water, pool drainage, paint rinse, and landscape chemicals. Implementing Rules Relating to Water Quality are adopted under ROH 14-12. Coastal neighborhoods like Portlock, Kuliouou, and Hawaii Kai Marina areas face special scrutiny because discharges flow directly into sensitive nearshore ecosystems, including Maunalua Bay conservation areas.
Illicit discharges such as car-wash runoff, pool drainage, or chemical dumping into storm drains can result in administrative orders and civil penalties.
