OP-T2-48: Weather-Informed Irrigation

The UW utilizes a network campus central control system with an integrated weather station to adjust irrigation programs for season changes. Some controllers also utilize stand alone rain sensors. In addition to weather sensors, the UW also utilizes irrigation submeters and master valves to enhance irrigation monitoring and control, installs high efficiency irrigation such as multi-trajectory, rotating stream sprays, subsurface drip irrigation and pressure regulating automatic control valves. Next, the UW fields a dedicated highly trained irrigation shop and leverages teamwork from other end user stakeholders such as gardeners, plumbers, electricians, information technology specialists, and athletic field groundskeepers. Additionally, the irrigation shop utilizes irrigation record drawings, an irrigation water conservation plan, and is developing GIS supported irrigation asset management. Last, in addition to providing irrigation system lifecycle maintenance, irrigation shop personnel collaborate with construction management, architects, engineers, and contractors to provide existing conditions, design guidelines, and construction support for capital, student, and in-house construction.
