In Southern California, water conservation is a way of life. Water conservation measures are an important first step in protecting our water supply, as we come to appreciate the fact that fresh water for drinking, irrigation, industry, and other uses is a precious resource and should not be wasted.

We must continually seek strategies and tools for using less water around our homes and businesses all the time - and not just during occasional droughts. Such measures not only save the supply of water, but also can save you money by reducing your water bill.

In partnership with the Inland Empire Utilities Agency (IEUA) and the Regional Water Conservation Partnership, the City of Ontario is pleased to offer a series of water conservation rebates to its residents and businesses. These rebates offer an opportunity to save money and achieve significant water (and energy) savings throughout the year.

Funding is limited, so please check with IEUA for rebate availability and amounts:
