A brief description of the institution's water recovery and reuse initiatives:

The Willow Creek Center and Rock Creek campus have a rainwater harvesting system.

Water conservation is also integrated into all new construction, from water-saving fixtures to innovative stormwater management. For example, the CLIMB Storm Water Education Plaza project was selected as one of the “2013 Top Storm Water and Erosion Control Projects” in the U.S. by Storm Water Solutions!


A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

Water Consumption
Facilities Management Services has installed low flow aerators on our bathroom and break area faucets. Our faucets either are metering faucets (which provide a predetermined amount of water) or motion based sensor faucets. FMS has also installed low flush parts in toilets and urinals, which reduces the number of gallons per flush. See also Drinking Water.
