Optional Fields

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 a pledge to reduce water during the 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.
