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

A brief description of the institution's water recovery and reuse initiatives:
UW's Green Building Standards requires major capital projects to be designed to achieve at least 50% reduction for indoor and outdoor potable water use as compared to current code as a baseline. As a result, the recently completed Hans Rosling Center for Population Health installed a large rainwater cistern to recover water that is subsequently used for flushing of urinals and water closets as well as subsurface irrigation.
A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
UW's Green Building Standards requires major capital projects to be designed to achieve at least 50% reduction for indoor and outdoor potable water use as compared to current code as a baseline. As a result, major capital projects that renovate areas on campus often replace existing plumbing fixtures with low-flow fixtures.
