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

The 2012 Baseline was adapted because it corresponds with the beginning of many CMU sustainability objectives outlined in the Sustainability is Central Report attached below.

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

This following information is directly from the Sustainability Is Central 2018 Sustainability Report attached below:

1. "Bottle filler water fountains installed around campus (ongoing)
In an effort to minimize plastic bottle waste, installation of bottle filling stations on new
and existing fountains across campus is ongoing. Currently, there are approximately 60 stations located on campus. Filling stations record the number of plastic water
bottles saved by refills at each station."


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

This following information is directly from the Sustainability Is Central 2018 Sustainability Report attached below:

1. Reduction in onsite well water consumption
"Well water is used in the Powerhouse and to irrigate the band field. Well water consumption has been reduced by 16.4% since 2011."

2. Installation of storm water detention systems
"As defined by Contech Engineered Solutions, storm water detention systems “are employed on a site to reduce the quantity of stormwater runoff leaving a site by temporarily storing the runoff that exceeds a site’s allowable discharge rate, and releasing it slowly over time.” Two of these systems will be installed on campus: one in the Lacrosse Field and one in the Freshman Parking Lot. These systems are projected to exceed existing standards."


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

This following information is directly from the Sustainability Is Central 2018 Sustainability Report attached below:

1. Air conditioning systems converted from watercooled to air-cooled systems
"Air conditioning systems in Dow Science were converted from water-cooled to air-cooled systems, saving significantly on water. Explore campus landscaping options that incorporate plants which require less frequent watering, such as rain gardens and xeriscaping (ongoing). Facilities Management (FM) is continuing to explore the use and placement of plants that reduce the amount of necessary watering."

2. Install low flush or dual flush toilets and low flow faucets (ongoing)
"Low flush toilets and low flow faucets continue being installed on campus."
