Level of ”Physical Risk QUANTITY” for the institution’s main campus as indicated by the World Resources Institute’s Aqueduct Water Risk Atlas:
Low

Total water use (potable and non-potable combined):
Performance Year Baseline Year
Total water use --- 333,095,620 Gallons

Potable water use:
Performance Year Baseline Year
Potable water use 254,704,360 Gallons 333,095,620 Gallons

Start and end dates of the performance year and baseline year (or three-year periods):
Start Date End Date
Performance Year July 1, 2016 June 30, 2017
Baseline Year July 1, 2012 June 30, 2013

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

A 2013 baseline was established based on goals set forth by the University to reduce water consumption (gallons/campus acre) by 20% by 2020 over the 2013 baseline year. Therefore, data and knowledge about initiatives occurring between these time periods can be reported which may influence fluctuations in water consumption.


Figures needed to determine "Weighted Campus Users":
Performance Year Baseline Year
Number of students resident on-site 3,793 3,843
Number of employees resident on-site 20 17
Number of other individuals resident on-site and/or staffed hospital beds 0 0
Total full-time equivalent student enrollment 12,281 12,222
Full-time equivalent of employees (staff + faculty) 4,439 5,217
Full-time equivalent of students enrolled exclusively in distance education 3,265 631
Weighted campus users 11,044.50 13,571

Potable water use per weighted campus user:
Performance Year Baseline Year
Potable water use per weighted campus user 23,061.65 Gallons 24,544.66 Gallons

Percentage reduction in potable water use per weighted campus user from baseline:
6.04

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area 7,815,345 Gross Square Feet 5,692,088 Gross Square Feet

Potable water use per unit of floor area:

Vegetated grounds 265 Acres 265 Acres

Total water use (potable + non-potable) per unit of vegetated grounds:

A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:

SLU has committed to reducing water consumption by 20% by 2020 over a 2013 baseline. As part of this goal, water savings tips and awareness information is shared during presentations, new employee orientation, and new student orientation. Savings have been realized, as the University achieved its goal, but aims at ensuring levels are consistent through 2020.


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

Rainworks stormwater management garden, also known as Best Management Practices (BMP) garden installed in 2014, contains three 50 gallon rain barrels with an overflow option. These are used for drip irrigation to water the surrounding plants.


A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):

Use of auto-flow/auto-flush valves are determined on a project-by-project basis.
Low flow plumbing fixtures, low flow valves or aerators are installed on existing fixtures whenever possible.
