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

Water recycled/reused on campus, performance year:
946,300 Gallons

Recycled/reused water withdrawn from off-campus sources, performance year:
0 Gallons

A brief description of any water recovery and reuse systems employed by the institution:

We have a storm water catch system on top of 17th ave res hall and on the land care building.

A brief description of any water metering and management systems employed by the institution:

We actively meter potable water consumption. We bill individual Colleges and departments for their water use.

A brief description of any building retrofit practices employed by the institution, e.g. to install high efficiency plumbing fixtures and fittings:

State of Minnesota Sustainable Building Guidelines (http://www.b3mn.org/guidelines/index.html) specify low flow fixtures.

A brief description of any policies or programs employed by the institution to replace appliances, equipment and systems with water-efficient alternatives:

The goal is to encourage and increase purchasing that reflects the University's commitment to sustainability. This will further our efforts to promote environmental factors such as:
Conserving natural resources,
Minimizing environmental impacts such as pollution and use of water and energy,
Eliminating or reducing toxics that create hazards to workers and our community,
Supporting strong recycling markets,
Reducing materials that are land-filled,
Increasing the use and availability of environmentally preferable products that protect the environment,
Identifying environmentally preferable products and distribution systems,
Rewarding manufacturers and vendors that offer environmentally preferable products.

A brief description of any water-efficient landscape design practices employed by the institution (e.g. xeriscaping):

The university uses native plantings wherever possible, and irrigation grading and plant material selections are taken into considerations.

A brief description of any weather-informed irrigation technologies employed by the institution:

The University has two weather stations that feed data to the computerized central controller. The controller runs all of the irrigation systems. The data is used to calculate evapotranspiration (ET) rates, then the controller sets run times based on the previous day's weather conditions. (This is done on 98% of our systems, our goal is 100%).
The stations also have rain sensors that are set to shut down systems (rain delay) after we receive .25" of rain (this happens on 100% of our systems).

A brief description of other water conservation and efficiency strategies employed by the institution:
