Help Keep Maunalua Bay Clean!

You can help keep Maunalua Bay clean by signing up for a free rain water assessment!


Mālama Maunalua and 3Rwater are partnering to provide rainwater assessments to properties between Kāhala and Hawaiʻi Kai. A rain water assessment involves doing a quick evaluation of a property to determine the best ways to mitigate runoff and flooding. Solutions are proposed after an assessment which are as simple as installing a rain barrel or a rain garden. Rain water assessments are the first step in learning how you can help protect the bay starting from your home!
