Our Slow the Flow sprinkler evaluations help Coloradans use their water wisely. Our professional team will be on-site to perform tests and a visual inspection, provide a customized watering schedule, educate you about your system, and recommend ways to improve efficiency and reduce water waste.
Sprinkler evaluations are available for FREE in partnering water provider districts. We encourage you to register now for our 2025 season for a residential or non-residential evaluation. Appointments are available on a first-come, first-served basis during the irrigation season.
We’ll evaluate the sprinkler system at your personal home. This includes a visual inspection of your irrigation zones, efficiency tests, and a customized watering schedule.
We’ll evaluate the sprinkler system at your business, HOA, or other institutional property. We’ll recommend actionable steps to improve its efficiency and reduce water waste.
Stop watering during a rainstorm! We’ll upgrade your personal home’s irrigation system with a smart controller or rain sensor installation at little to no cost to you.

“I’m so glad we had Resource Central’s audit this year! Your sprinkler tech was very friendly and knowledgeable. He was happy to teach me about my system and how I could make slight tweaks to water my lawn more efficiently. Our lawn looks way better this year, and we’re not watering any more. What an awesome free service! Thank you!“

“The technician was excellent in knowledge and customer service. They found a broken sprinkler that was really adding to loss of water. Thanks for this program and the staff.”

“It is a great program, and every household should do it. It gave me a lot of useful information that I didn’t know about my lawn and how to water it!”
