A brief description of the source of non-potable water and how it is used:
The campus has a dedicated non-potable water system used for landscape irrigation on the central campus. This system pumps lower- quality shallow groundwater for supply. This system decreases demand on the higher-quality potable water supply. Additionally, the campus wastewater treatment plant produces reclaimed water that can be used without restrictions for irrigation. The reclaimed water is used for landscape irrigation in the wastewater treatment plant district. Lastly, a rainwater harvesting system is in place at the Robert Mondavi Institute for Food and Wine. The system has 4 tanks with a storage capacity of 176,000 gallons. The water is used for non-potable uses within the building (e.g., toilet flushing).
Tertiary-treated wastewater from the on-campus wastewater treatment plant is used for irrigation of landscaping at the treatment plant. This is a pilot project to learn how the landscape performs with the tertiary-treated water.
