A brief description of the institution's water-related behavior change initiatives:
Water conservation measures in our residence halls include the 5 minute shower campaign, water conservation stickers, and shower timer distribution. Students take pledge to reduce water during energy games. We also promote trayless dining in the dining halls.
A brief description of the institution's water recovery and reuse initiatives:
UCLA has an award winning water reclamation program that captures condensate from laboratory and HVAC equipment. In 2019 the program saved over 34 million gallons of water. News story on award: http://newsroom.ucla.edu/stories/ucla-wins-water-efficiency-project-of-the-year
Additionally UCLA has a storm water collection from roof and Air Handling Unit condensate collection system at Geffen Hall, and building greywater collection systems at the Wasserman Football building and Engineering VI Phase 1.
A stormwater collection and reuse for irrigation system was also recently installed at Parking Structure 9, the result of a student applied research project through Sustainability Action Research: http://ioes.ucla.edu/sar.
A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
UCLA has retrofitted around 300 campus urinals with low flow and hybrid waterless urinals, as well as thousands of toilets and showerheads in the residence halls. New building projects are required to meet LEED Silver or higher water requirements and a specific number of water points.
