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

It is not a formally adopted baseline. WKU Facilities Management tracks utility use including water.

Water recycled/reused on campus, performance year:
124,000 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Recycled/reused water withdrawn from off-campus sources, performance year: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:

Several rainwater harvesting systems have been installed at WKU. At three sites on the main campus, and one site at the WKU farm, rainwater is collected from rooftops into large cisterns. On campus, one of two 550 gallon cisterns is located near the Department of Facilities Management and the other is at the Health Services building. The water from the cisterns is dispersed to drip lines that irrigate local gardens. At the Dept. of Facilities Management maintenance barn at South Street, six 2,600 gallon cisterns collect water off the barn roof, which is used to fill an irrigation truck for campus trees and gardens. On the Farm, two 1300 gallon cisterns collect water from the livestock barn roof. This water is for many uses, including spraying down the Expo Center arena floor to reduce dust.

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

While individual buildings are not all metered for water, our rainwater collection systems are metered to track use.

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

WKU entered into an Energy Savings Performance Contract (ESPC) with Johnson Controls Inc. in 2009. WKU’s ESPC includes $9.7 million in energy reducing and facility improvements. Thirty-eight existing buildings have been impacted with 2,114 water saving fixtures.

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

In addition to the water saving fixtures described above, low-flow faucet heads, toilets, and shower heads are being systematically installed across campus.

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

Landscape plants used are primarily native and drought tolerant, and several xeriscape gardens have been installed around campus.

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

Weather and soil moisture informed irrigation aids in minimizing water used for irrigation.
