A brief description of when and why the water use baseline was adopted:
This was a drought year for Colorado and marked the beginning of a long-term commitment at CSU to better water management and conservation.
Water recycled/reused on campus, performance year:
Recycled/reused water withdrawn from off-campus sources, performance year:
A brief description of any water recovery and reuse systems employed by the institution:
Untreated raw water is used for irrigation on nearly all CSU properties.
A brief description of any water metering and management systems employed by the institution:
Water is delivered to campus through master meters.The university operates building level metering for almost all the buildings on campus. Those meters are currently read manually, but an AMI metering program is being implemented and most water meters will be converted into "real time" meters within the next year.
A brief description of any building retrofit practices employed by the institution, e.g. to install high efficiency plumbing fixtures and fittings:
CSU has made 1 pint/flush urinals & 1.28 gpf toilets standard in all bathroom remodels.
A brief description of any policies or programs employed by the institution to replace appliances, equipment and systems with water-efficient alternatives:
Autoclaves are notorious for using lots of water to cool condensate before it is sent down the drain. CSU has retrofit 42 autoclaves on campus w/ water saving devices that save the university 15 million gallons/year. These features are now specified in all new autoclave installations.
A brief description of any water-efficient landscape design practices employed by the institution (e.g. xeriscaping):
In accordance with LEED guidelines, all new construction on campus includes drought tolerant plants and active xeriscaping. Nearly all new plants on campus are water conserving.
A brief description of any weather-informed irrigation technologies employed by the institution:
A local data system monitors weather patterns and irrigation systems require manual overload to conserve water during a storm.
A brief description of other water conservation and efficiency strategies employed by the institution:
