The University of San Diego has reduced its annual water consumption by more than 38 million gallons since 2006. In 2016, the campus had its lowest water usage in more than 25 years. Facilities Managment staff continues to replace ornamental grass with drought-friendly material to reduce water consumption. USD’s use of a weather-based irrigation system utilizes wireless technology to allow sprinklers to automatically adjust to weather, reducing over-watering and allowing us to be responsive to dynamic weather conditions. Retrofits such as low-flow aerators on faucets, water efficient toilets, and low-flow shower-heads have been implemented throughout campus buildings to help realize these savings.
