A brief description of when and why the water use baseline was adopted:
On April 1, 2015 Governor Jerry Brown signed an executive order implementing a mandatory 25 percent water cutback in cities and towns across the state from 2013 usage levels. It took effect June 1. The University began compiling water use data in 2015 as a result.

A brief description of the institution's water-related behavior change initiatives:
A brief description of the institution's water recovery and reuse initiatives:
The university has installed and maintained seven different Bio-swales to help mitigate stormwater runoff from new building construction projects. The University Center has two swales. Biological sciences has one swale. Alumni house has two swales. The JL Gym has one swale. Baseball batting cages have one swale. And the Tennis complex has one swale. Knoles field is also used as a water retention location for the city after heavy rain events. The Greenhouse has a water recycling system which saves over 100,000 gallons a year. As of 2020, 100% of irrigation water is non-potable.
A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
In 2019 the university took part in a campus wide low flow toilet replacement program offered though the San Joaquin County Air Pollution Control District. With this program we were able to replace over 850 toilets with low-flow toilets. Estimated water savings are over 2 million gallons/year. faucets and shower-heads are all low-flow.
The grounds department has upgraded irrigation infrastructure with high-efficiency nozzles and drip irrigation. We have incorporated these options to our university guidelines and standards.
