Clean Water For Hawaiʻi

WAI works to mitigate the Hawaiʻi cesspool crisis, protect water quality, reduce sewage pollution and restore healthy watersheds.

Hawaiʻi has over 83,000 cesspools that discharge over 52 million gallons a day of wastewater into Hawaiʻi’s waters. These cesspools and failing septic systems contaminate drinking water, ruin underground aquifers, and pollute marine environments. WAI helps combat these issues by providing innovative, affordable, and eco-friendly solutions to waste and wastewater management for all.

In ʻŌlelo Hawaiʻi (Hawaiian Language), 'wai' carries the meaning of water.
