A brief description of the institution's water recovery and reuse initiatives:

In the University Center, the water reuse system recycled 60,000 gallons of rainwater in 2020 and used it to flush urinals.


A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

Reduced water usage is always considered when doing any major projects or remodeling that includes work on the plumbing systems. Lower flow aerators, lower flow flush valves and lower flow shower heads have been included in recent projects including May Hall, McMillan Hall, Grimm Hall, and Rodli Hall.

The University center has dual-flush valves on all toilets as well as the EcoCubes used on all urinals reducing to 3 flushes per day.
