  • System pressure

  • Controllers

  • Site conditions and irrigation scheduling

  • Issues that cause higher water use, such as valve malfunctions, high or low pressure, sprinkler misalignment, poor drainage, breaks and leaks and runoff, etc.  

Participants will receive a written report that includes:

  • Data collected during the survey

  • Recommendations for improving the site’s irrigation efficiency including system repairs, equipment updates, and irrigation scheduling 

  • Information about available financial incentives to help with the cost of recommended improvements
