A brief description of when and why the water use baseline was adopted:

FY00 was a drought year for Colorado and marked the beginning of a long-term commitment at CSU to better water management and conservation.

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:

The Green Warrior campaign encourages students to adopt sustainable behavior choices and includes several actions related to water conservation like taking shorter showers, never leaving water running while brushing teeth, and using the Nalgene bottle all incoming students receive to eliminate the use of bottled water on campus.


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

Untreated raw water is used for irrigation on nearly all CSU properties. Therefore, the total water use & potable water use will not match.


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):

CSU has made 1 pint/flush urinals & 1.28 gpf toilets standard in all bathroom remodels.
