A brief description of when and why the water use baseline was adopted:
The baseline year of 2007 was the year prior to the adoption of the campus first water use goal that set in motion more mitigation measures; 2007 usage correlates with the UC Policy baseline of three years average 2006-2008.

A brief description of the institution's water-related behavior change initiatives:
The ongoing drought conditions in California have kept messaging about water use visible in signing at the Recreation Sports facilities and various locations around campus.
A brief description of the institution's water recovery and reuse initiatives:
Rainwater is reused each year for irrigation at the UC Berkeley School of Law. In addition, some recycled/reused water from the Eshleman rain water system is used in the building. Finally, the Chou Hall at the Haas School of Business also recycles rain water capture and reuse.
The campus also uses well (ground) water for pressure washing of sidewalks, pathways, egresses, entries, patios and stairs.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
The campus during renovation projects replaces domestic water features with more efficient models as a regular practice.
Students working with housing staff have tested and installed different low-flow shower heads and toilets in residence halls. The Green Labs program has piloted autoclave retrofits that show to achieve water savings. Large equipment replacements like cooling towers have improved conservation.
