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

Opted to use the three year average in order to account for seasonal variations in water use. July-June was used because it is the university's fiscal year, and is the common time period that records are kept in.

Water recycled/reused on campus, performance year:
0 Gallons

0 Gallons

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

WMU does not currently recycle/reuse water on campus.

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

All buildings are metered at the building level for water consumption. Evaporative systems such as cooling towers and building automation system controlled irrigation systems are metered. At a minimum all water meters are monitored on a monthly basis.

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

WMU has retrofitted low flow fixtures in many of its existing buildings, and is currently in the process of converting some fixtures to even lower flow. Fixtures include water closets, urinals, faucets, and showers.

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

WMU worked with the laundry vendor to upgrade laundry machines to Energy Star washing machines, which use less water.

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

WMU has he ability to monitor and control irrigation systems through the Building Automation System. WMU also utilizes native plants and vegetation to minimize the need for irrigation.

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

WMU has the ability to but is not currently employing weather informed irrigation technologies.
