The water use baseline, 2005, was adopted as part of the University of Idaho's submission to the American College and University Climate Commitment (ACUPCC) and the university's Climate Action Plan published in 2010.
The 2005 Energy Policy Act established conservation goals and objectives for energy and water. UI has been monitoring and actively participating in water conservation since 1955. In 1979, a water reclamation program was initiated with the aim of reducing university dependence on the Palouse Basin Aquifer. UI and the Palouse Basin Aquifer Committee are seeking alternative water sources and preserving local water resources for future generations.

Optional Fields
Sample of water awareness and behavioral initiatives:
The Student Sustainability Cooperative created and disseminated a Stormwater Outreach pamphlet as part of the University’s MS4 permit with the DEQ. The SSC also hosted multiple events where students were invited to come out and label catch basins and learn more about water quality and conservation.
The SSC’s Green Living Guide included information about how to reduce water usage in dorms, apartments, and other living groups on campus.
The University of Idaho has been an active member of the Palouse Basin Aquifer Committee (PBAC) since 1976. This multi-jurisdictional committee was established "to ensure a long-term, quality water supply for the Palouse Basin region".
Water-related behavior change initiatives hosted by the Sustainability Center and many partners:
-There is an ongoing effort to install water bottle refill stations in new buildings, remodels, and many retrofits have been funded by student-led grant projects.
-Ongoing effort to plant native plants on campus that require less irrigation
-Student volunteers install educational medallions on campus storm drains to discourage the pouring of harmful liquids directly into the local creek.
-water conservation educational program which includes recommendations, pamphlets, website, best practices, etc.
-Building standards to reduce water use in buildings including low flow fixtures, closed loop heating/cooling water distribution

A brief description of the institution's water recovery and reuse initiatives:
Reclaimed Water Irrigation: Non-potable water comes from the City of Moscow Sewage Treatment Plant and from Aquaculture Labs discharge water. The University of Idaho irrigates over 183 acres with reclaimed, non-potable water. In 2021 alone, the U of I used 93 million gallons of reclaimed water to irrigate our campus. UI also has two building level rainwater recapture systems.
Ongoing initiatives:
-Expand the use of non-potable irrigation water.
-Expand the use of automated irrigation systems, especially with non-potable water, to reduce water consumption.
-Ongoing efforts to improve steam condensate return systems.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
University of Idaho adopted and implemented construction standards for the installation of low flow fixtures on new construction and/or replacement remodels. In addition, we have policies in place which do not allow equipment that requires water for cooling purposes.

Data source(s) and notes about the submission:
Elmer Johnson, Water Systems Manager; McKinstry
sources: daily meter readings for the domestic water wells and reclaimed plant from McKinstry
*The College of Agriculture and Life Sciences operates 3 wells on the West Farm. There is no data on water withdrawal from these wells, but it is estimated that they contribute to less than 1% of total campus water withdrawal.
