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

This is the earliest date for which we have accurate data.

Water recycled/reused on campus, performance year:
20,000,000 Gallons

Recycled/reused water withdrawn from off-campus sources, performance year:

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

Denison uses water sourced from wells, ponds, streams, and harvested rainwater for its irrigation use. The boilers for the heating plant use non-potable well water.

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

Meters are on nearly all of the buildings(some share meters). We have an end-of-the-year summary of water usage for many of the buildings.

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

Denison has been systematically replacing all toilets and fixtures with low flow options. Nearly 100 percent of shower fixtures are low flow. All sinks are fitted with low-flow aerators.

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

Denison defaults to appliance purchases that are Energy-Star and WaterSense rated/labeled.

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

Denison has a general landscaping plan that gives priority to native species that are adapted to living in Ohio's climate. Generally these plants do not require extensive irrigation.

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

Sensors located around campus detect moisture in the soil and will activate sprinkler and irrigation systems accordingly.

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

In addition to utilizing low-flow fixtures and WaterSense products, Denison limits its use of potable water for irrigation purposes.
