Baylor University Centralized Irrigation System Saves Water, Reduces Maintenance

Andy Trimble, Director of Campus Grounds for Baylor University's Facility Services in Waco, Texas, discusses his university's conversion to a centralized irrigation system on campus. Before centralizing the system, Baylor's facility services department spent 224 labor hours a year in order to turn the system on and off and make seasonal adjustments. The new system has enabled the department to better allocate those hours and find estimated savings of $150,000 a year on the 1,000-acre campus.
