A brief description of the institution's water-related behavior change initiatives:

One of the major changes related to water use is the increase in messaging about using reusable water bottles, as well as installing an additional 40 water bottle filling stations in the last 1.5 years.


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

The Grounds dept. on the Oshkosh campus has purchased four large water tanks (vol) that collect rainwater and are used for watering plants around campus.


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

We retrofitted the water-cooling systems at Blackhawk Commons with air-cooled equipment, reducing the use of water, and in 2005, replaced the natural grass football field at Titans Stadium with artificial grass resulting in an estimated savings of 850,000 gallons of water used for irrigation. We have replaced 1,006 older 4.18 gpf toilets with 1.6 gpf toilets and Installed 5 water-less urinals. There has been 1,181 low-flow restrictors and applicable adapters installed onto threaded faucets.
