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.

Figures needed to determine "Weighted Campus Users":

Optional Fields

A brief description of the institution's water-related behavior change initiatives:

Water savings tips and actions are part of the Green Office Program, a program for employees. It is also a section in the Sustainable living guide geared toward students.

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 winter 2023 a magnation device was installed on the Stockton campus irrigation pump and at the pump for the outdoor pool. The magnation device utilizes engineered magnetic fields to remove impurities from the water and build-up in pipes. This results in needing less energy to pump water through the system, fewer water conditioners, fewer pool chemicals and less overall water use due to better water absorption by the soil. Previous initiatives include replacing over 850 toilets with low-flow toilets in 2019 and upgrading irrigation with high-efficiency nozzles. As standard operations, all faucets and shower-heads are low-flow as are new toilets. The university is currently exploring options to further upgrade irrigation systems, particularly at the Sacramento campus. 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.
