Rain Barrel Catchment Program Giveaway

The County of Maui Department of Water Supply is excited to announce its first Rain Barrel Catchment Program. As part of our continued efforts to promote water conservation on our island, we are currently giving away free 50-gallon, eco-friendly Ivy Rain Barrels while supplies last.

Ultra-High Efficiency Toilet (UHET) Replacement Program

UPDATE: With an overwhelming response from the public to reconsider a requirement to have a certified plumber install free UHET toilets, DWS has now decided to allow single-family home owners to receive the UHET toilets with just a commitment date for installation and before/after photos.

Under the new DWS UHET Toilet Replacement Program, the public may choose to replace older qualifying toilets with new, EPA WaterSense, ultra-high-efficiency toilets (UHET) rated at 0.8 gallons per flush (gpf).

County of Maui Landscape & Gardening Handbook

The 2011 County of Maui Landscape and Gardening Handbook was developed by the Department of Water Supply as a resource for people who want to save water in the yard and learn about what and how to plant in certain areas. It gives a wealth of information on xeriscaping, including xeriscape’s seven basic principals, list of native plants appropriate for each plant zone, and other useful resources.

County of Maui Community Gardens Project

The Department of Water Supply, along with Maui community groups, participates in an assortment of garden projects. The goal of the projects is to demonstrate the benefits of using native plants and water conservation in the landscape.
Please visit the Community Gardens Project to see some of the xeriscape and native plant gardens cultivated around Maui.
