A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:

Colorado College has instituted specific staff training as well as the installation of sub meters on large water consuming infrastructure such as the pool, cooling structures, etc. Building automation is used to identify larger than normal fill volumes.


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

Landscape zones are irrigated with City of Colorado Springs-supplied non-potable water, a combination of raw water from a local reservoir and treated domestic wastewater. Additionally, CC has started recovering grey water in the central heating plant to condense flu gas and recover heat.


A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):

In general, Colorado College has phased in efficient water fixtures as older ones have retired. Fixture retrofits have included outfitting existing faucets with low-flow faucet aerators, replacing shower heads, replacing tank and flush valve toilets with low-flow models, and upgrading urinals to current standards. In 2012, while renovating Worner Student Center and Rastall Dining Hall, the College replaced the existing dishwasher with a more efficient one and retrofitted toilets and urinals with low-flow units. Recently, the Facilities department updated the Bemis shower fixtures to be more efficient.
