Water

UNMC/Nebraska Medicine’s water consumption typically peaks in the mid-to-late summer coinciding with the time of year that requires the heaviest cooling loads and the peak time for irrigating lawns and landscaping. UNMC/Nebraska Medicine’s past energy conservation projects have reduced building water demand. Specifically, annual building water use decreased 36 percent from calendar year 2010. The goal and strategies for this section seek to build on this recent success and primarily focus on the other two areas of opportunity regarding water use: irrigation and indoor water use. By achieving their 2023 goal, UNMC/Nebraska Medicine will significantly reduce the amount of water that needs to be treated and supplied to campus, and they will potentially save up to $50,000 annually.

In 2017 several goals were updated with a more ambitious timeline and metric.  UNMC and Nebraska Medicine have committed to achieving Net Zero Water by 2030, which would be a 54% reduction in water use.

Baselines

The baseline figure for water is the
total annual gallons of water used by
UNMC/NM and represents an average of
calendar years 2010 and 2011.
Primary Metric:
• Total annual water consumption
• Baseline: 225,164,787 gallons per year
Secondary Metric:
The secondary metric is normalized for
the total size of campus facilities, and it
can potentially be used to compare the
UNMC/NM campus to other health care
and university facilities.
• Water-use intensity per square foot
• Baseline: 53 gallons per square foot
(based on total water consumption
and 4,537,543 square feet, which
does not include parking garages)

Goal

Water Consumption:
Reduce annual gallons of water by 10
percent by the end of 2023 (achieved)

Updated Goal

Net Zero Water by 2030

The Net Zero Water Guidebook defines net zero water as “using only as much water as falls on your site and eliminating all water quality impacts from the site.”

Based on current site, this would be the equivalent of reducing to 104 Million gallons per year
