The DoD has numerous facilities that use inefficient irrigation processes timer based and manual watering systems that are no longer sustainable given the limited water supplies in many U.S. locations and future water demand. Smart water conservation systems may provide DoD a pathway for preserving green landscape assets while simultaneously reducing potable water demand for landscape irrigation. This project demonstrated the retrofit of a typical DoD building with an integrated suite of commercially available water conservation technologies designed to reduce potable water usage. Specific technologies tested include evapotranspiration irrigation controller centralized and site-specific sensor inputs such as ET gauge, rain, soil moisture, leak detection efficient water delivery systems and rooftop rainwater and HVAC condensate harvesting systems to displace potable water used for irrigation. This report documents demonstration results for a smart water conservation system implemented at a large administrative building located at Naval Base Ventura County, California. The smart water system achieved an 81 reduction in potable water use when two similar plots of turf, one using smart irrigation practices and the other using traditional timer, were compared.
