Maui County is struggling with one of the worst ongoing drought crises in over a decade. As a result, there has been less water to collect, treat and deliver to your homes. Water use restrictions are likely to continue as the Department of Water Supply (DWS) implores everyone to conserve water.
As a reminder to conserve water during the summer months, DWS has created a water conservation awareness campaign called, “ Don’t Waste a Drop.
The Department of Water Supply is an agency of the County of Maui. Our mission is to provide clean water efficiently. We provide water to approximately 36,400 services on Maui and Molokai. The water we provide meets all state and federal water quality standards. Take a look around our site to learn more. The Department needs your help! Please conserve water. For easy ways to use less water (and save money), see our tips on Water Conservation.
