Kailua's beach-adjacent watersheds are protected by ROH Chapter 43, Article 11 and Chapter 14, Article 12, which restrict non-stormwater discharges to the city's separate storm sewer system.
Honolulu's MS4 stormwater regulations prohibit most non-stormwater discharges into streets, gutters, and storm drains that flow to Kailua Bay and Kaelepulu Pond. Section 43-11.12 governs connections to the city's separate storm sewer, while Sec. 43-11.22 prohibits discharging effluent other than stormwater. Administrative Rules Relating to Water Quality adopted under ROH 14-12 set pollutant limits and best management practices for construction sites and ongoing operations. Common residential violations include washing paint, concrete slurry, or car-wash detergents into street drains, all of which flow essentially untreated to the ocean.
Illicit discharges, failed BMPs at construction sites, or uncontrolled runoff from private property can bring substantial civil penalties.
