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

The 2010 baseline year was selected to maintain a consistent emission-inventory history between the performance year and the year we had previously submitted a STARS report.

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

Primary shifts have occurred around passive management (e.g. low flow) and through selective landscaping.


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

Outside of a few, select gray water and water catchment systems, there is no comprehensive campus initiative.


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

Although not fully represented within the reporting period, largest impacts were recently made with to a campus-wide upgrade of the irrigation control system that better accounts for weather variation and soil needs.

Low flow toilets, sinks, and fixtures are pursued throughout the campus. Implementation of these upgrades is consistent for the majority of renovations and new construction. There have been some obstacles implementing these changes in the Health Sciences campus due to water line contamination concerns.

Significant work was also done to identify and repair leaks in the high temp system and changes in plant cooling towers resulted in significant water savings.

SOURCES
Facilities Sustainability & Energy tracks water use of utility bills and well water over time. Water systems are associated with buildings along with their floor area, construction date, and demolition year to account for changes over time. The university purchases most water from Salt Lake City, but some irrigation water pulled from a well system on site.

NOTE: The University system also serves water to the Intermountain Healthcare Primary Children's Medical Center, which that area has been added as a part of the system boundary. That building area is not applicable to energy and campus boundaries.

NOTE:University began tracking well pump non-potable water used for irrigation in 2013. In 2010 the University began gradually switching irrigation from 100% potable water from the Salt Lake City water system to non-potable well water. In addition to the progress made in system efficiencies noted above, the reduction in potable water use per weighted campus user is also due in part to the shift to well water for landscape irrigation.

C. Water Distribution System (1) The source of the University’s domestic water distribution system is Salt Lake City’s water supply system. (2) Water conservation measures are to be designed into, and implemented on all new construction or substantial remodeling projects. No project is to increase the quantity of water consumed; indeed; water consumption should decrease with the completion of each project.
