Slow the Flow: Residential Sprinkler Evaluations

Slow the Flow sprinkler evaluations help Colorado residents use their water wisely. Gain knowledge about your system, get a customized watering schedule, and learn ways to improve efficiency and reduce water waste. Residents in partnering water provider districts can receive on-site evaluations for FREE. Colorado yard care just got easier!

Residential appointments are typically scheduled from June through August/September, Monday to Friday, 8:00 AM-4:30 PM, and last 1-1.5 hours. All evaluations take place on-site at your property and require an in-ground sprinkler system in good working order.

We encourage you to register for our 2025 waitlist now because we offer appointments on a first-come, first-served basis during the irrigation season!

What’s Included in Your Free Evaluation

Our trained associates will be on-site to do a complete visual inspection of your system, identifying problem areas, as well as performing several tests on your system to create an efficient watering schedule for your yard.

Why haven't I heard back about an appointment time yet?

Hang tight! We likely don’t have appointments available in your area just yet, or we haven’t reached your name on our waitlist. Once we have availability in your area, we will call, text, or email you to schedule your appointment. Look for email invites from “Slow the Flow” in your inbox.

What do I have to do to prepare for the appointment?

Make sure you activate your system and that it is in generally good working order before the appointment. If your system has major problems when we arrive, we won’t be able to complete a full appointment and we will not be able to reschedule. Also, an adult (18 years or older) must be on the premises during the entire appointment, so please plan accordingly.

How long does the appointment take?

The appointment typically lasts one to one and a half hours for most residential properties. You (or another adult) need to be on the property for the duration of the appointment. However, while we strongly encourage you to engage in the entire evaluation, you are only required to meet with our associate for the first 10 minutes and last 10 minutes of the appointment.

What does the evaluation involve?

Our associates will perform a visual inspection of all zones, making minor adjustments where they can and marking down any larger issues. They will then test certain zones to measure how much water the sprinklers emit and how evenly that water is distributed. By the end of the appointment, they will have an efficient watering schedule based off your specific system.

During this appointment can you help identify or fix leaks?

While our associates do look for obvious signs of a leak, our service is not for leak finding, and we cannot fix any leaks. We recommend finding a landscaper if you suspect you have a leak.

When does my evaluation report arrive?

You will be emailed your report by the end of the day of your evaluation. If you do not see your report in your inbox, please check your spam box, or email water@resourcecentral.org to have it resent. If you do not have an email, you will be mailed a paper report within two weeks of the evaluation.
