Water Wise Outdoor Surveys


Seasonal check-ups on your irrigation system is the best way to ensure it's performing as efficiently as possible. On average, about half of the water used on residential sites goes to landscaping. A well-maintained irrigation system can help you reduce your water use drastically. The Water Wise Outdoor Survey is a free service offered to single-family, multi-family and commercial properties with landscapes under ½-acre in Santa Clara County. During the outdoor survey, a trained irrigation professional will complete a comprehensive evaluation of your irrigation system. Please be aware that our surveyors do not carry tools to detect underground leaks, but they can help you narrow down whether a leak may be occurring indoors or outdoors.

Landscape Rebate Program

The survey can help identify and prioritize improvements that may be eligible for rebates through Valley Water's Landscape Rebate Program. Our Landscape Rebate Program is designed to encourage residents to convert approved high-water use landscape to low-water use landscape, as well as to retrofit existing irrigation equipment. Completing a survey can help prioritize what projects you should undertake.
