Did you know Oʻahu has separate storm drain and sewer systems? That means anything passing through Oʻahu’s storm drain system leads directly into the ocean; it does not get filtered through the sewer system.
We can take small steps to ensure that Oʻahu’s waters remain clean for us and our keiki. This website has been created to help you learn more about storm water pollution and how you can keep Hawaiʻi’s waters clean.
