WaterSense® Certified Homes
Did you know that some newly built homes use significantly less water than others?
One way homebuilders can help conserve Arizona’s water supplies is by constructing homes that earn a WaterSense® certification. Developed by the U.S. Environmental Protection Agency (EPA), WaterSense-certified homes are independently inspected and use at least 30% less water than typical new homes—without sacrificing performance.
As proud EPA WaterSense partners, and to encourage more water-efficient construction, the Central Arizona Project (CAP) and the Central Arizona Groundwater Replenishment District (CAGRD) created the Water-Efficient Construction Incentive Program (WECIP). The program offers eligible homebuilders a $1,000 rebate for each newly constructed home that earns a WaterSense 2.0 certification.

Why does this matter?
Water-efficient homes help reduce overall water demand, lowering the need to pump groundwater and supporting Arizona’s long-term water sustainability goals. Water-saving features may include high-efficiency plumbing fixtures, water-smart landscaping, efficient irrigation systems, and other design elements that help homeowners save water—and often money on utility bills.
This construction incentive program has proven popular. Since its launch three years ago, all available rebate funding has been fully distributed each year.
Rebate cycle underway for CAGRD’s Water-Efficient Construction Incentive Program
The fourth annual funding cycle is now underway, with $200,000 in rebates available for qualifying projects.
Homebuilders building in any CAGRD Member Land and the Member Service Areas of Copper Mountain Ranch CFD, El Mirage, EPCOR San Tan (both Active Management Areas), EPCOR San Tan Anthem, EPCOR West Valley, Global Water – Farmers Water Company, Metro Water – Diablo, Sahuarita Water Company, Spanish Trail Water Company, the Town of Marana and Vail Water Company can learn more here.



For Arizona residents shopping for a new home, WaterSense® certification is a feature worth looking for. A water-efficient home can help reduce water use from the day you move in while supporting a more sustainable future for Arizona.
