1.06 / 5.00 |
Level of ”Physical Risk QUANTITY” for the institution’s main campus as indicated by the World Resources Institute’s Aqueduct Water Risk Atlas:
Total water use (potable and non-potable combined):
Performance Year | Baseline Year | |
Total water use | --- | 24,091,490.70 Gallons |
Potable water use:
Performance Year | Baseline Year | |
Potable water use | 8,231,563 Gallons | 9,027,490.70 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, 2015 | June 30, 2016 |
A brief description of when and why the water use baseline was adopted:
Figures needed to determine "Weighted Campus Users":
Performance Year | Baseline Year | |
Number of students resident on-site | 355 | 354 |
Number of employees resident on-site | 4 | 4 |
Number of other individuals resident on-site and/or staffed hospital beds | 5 | 6 |
Total full-time equivalent student enrollment | 366 | 382 |
Full-time equivalent of employees (staff + faculty) | 129 | 125 |
Full-time equivalent of students enrolled exclusively in distance education | 0 | 0 |
Weighted campus users | 466 | 475.75 |
Potable water use per weighted campus user:
Performance Year | Baseline Year | |
Potable water use per weighted campus user | 17,664.30 Gallons | 18,975.28 Gallons |
Percentage reduction in potable water use per weighted campus user from baseline:
Gross floor area of building space:
Performance Year | Baseline Year | |
Gross floor area | 389,048 Gross square feet | 389,048 Gross square feet |
Potable water use per unit of floor area:
Performance Year | Baseline Year | |
Potable water use per unit of floor area | 21.16 Gallons per square foot | 23.20 Gallons per square foot |
Percentage reduction in potable water use per unit of floor area from baseline:
Does the institution wish to pursue Part 3 of this credit? (reductions in total water use per acre/hectare of vegetated grounds):
Area of vegetated grounds:
Performance Year | Baseline Year | |
Vegetated grounds | 35 Acres | 35 Acres |
Total water use (potable + non-potable) per unit of vegetated grounds:
Performance Year | Baseline Year | |
Total water use per unit of vegetated grounds | 0 Gallons per acre | 688,328.31 Gallons per acre |
Percentage reduction in total water use per unit of vegetated grounds from baseline:
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:
Some toilets in the Campus Center and Milas Hall are designed to save water by using different amounts of water when needed and have the appropriate signage.
A brief description of the institution's water recovery and reuse initiatives:
Olin College invested in the water efficiency and wastewater planning from its original construction. Seventy percent of the irrigation systems on campus are fed by well water.
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):
Olin has begun upgrading flushometers for the toilets in dormitories in order to make them low-flow toilets. They are Water Sense certified by the EPA. Faucets are also being upgraded in the dorms to low flow Water Sense certified. Shower heads are also being replaced so that they are low-flow.

Data source(s) and notes about the submission:
Level of risk was determined using the Water Risk Atlas: http://www.wri.org/applications/maps/aqueduct-atlas/#x=-71.27&y=42.21&s=ws!20!28!c&t=waterrisk&w=def&g=0&i=BWS-16!WSV-4!SV-2!HFO-4!DRO-4!STOR-8!GW-8!WRI-4!ECOS-2!MC-4!WCG-8!ECOV-2!&tr=ind-1!prj-1&l=11&b=terrain&m=group
Olin's water meter data was used to calculate potable water usage and the well water usage was estimated based on run time and flow rate of the well.
Estimated acres by James Bartholemy.
Jeremy Goodman provided people counts.
