Irrigation Check-Ups

• Free to residential customers

• Focus on “how to” for irrigation systems

• Referral to Licensed Irrigator

• Nearly 600 checkups since 2010

Why do an Irrigation Checkup?• Over-irrigation is common• Water use going to

outdoor landscape– 13% - 64% statewide– 45% - 75% in College

Station• Recognized Best

Management Practice• Savings of 5% - 30% post-

intervention

Irrigation Check-Ups

• NOT an Irrigation Audit• Identify and correct sources

of water waste: – Inefficient irrigation system

design– Poor maintenance and

operation practices– Excessive irrigation run times– Leaking/misdirected

sprinkler heads– Lack of understanding of

irrigation controller

Irrigation Check-Ups• Evaluate controller settings• Operate & inspect system• Provide a follow-up report

with recommendations• Detailed description of

system maintenance needs• Documentation of current

irrigation schedule• Recommended irrigation

schedule for current season

• Example of “No watering”

• Example of “Watering Needed”

Sprinkler Spruce Up Workshops•3 workshops in 2015 and 2016•Geared toward high water use neighborhoods•Licensed Irrigator with Agrilife imparts “tips of the trade” to help homeowners save water

Public Works Partnership

• Regular coordination on water use for City buildings and landscapes

• Service Level Adjustment for replacement of inefficient “clock” style controllers with efficient irrigation controllers in FY 17– Funded with Apache Corp. revenue
