"---" indicates that no data was submitted for this field

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

Total water use (potable and non-potable combined):
Performance Year Baseline Year
Total water use 171,512,869 Gallons 171,172,948 Gallons

Potable water use:
Performance Year Baseline Year
Potable water use 171,512,869 Gallons 171,172,948 Gallons

Start and end dates of the performance year and baseline year (or three-year periods):
Start Date End Date
Performance Year Jan. 1, 2020 Dec. 31, 2020
Baseline Year Jan. 1, 2011 Dec. 31, 2011

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

2011 was chosen because it is the most recent year in which we could confirm vegetated area and data accuracy.


Figures needed to determine "Weighted Campus Users":

Number of students resident on-site 8,262 7,762
Number of employees resident on-site 40 30
Number of other individuals resident on-site and/or staffed hospital beds 0 0
Total full-time equivalent student enrollment 30,434 26,573
Full-time equivalent of employees (staff + faculty) 5,060 3,648
Full-time equivalent of students enrolled exclusively in distance education 4,340 0
Weighted campus users 25,441 24,613.75

Potable water use per weighted campus user:

Percentage reduction in potable water use per weighted campus user from baseline:
3.06

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area 7,839,565 Gross Square Feet 6,803,381 Gross Square Feet

Potable water use per unit of floor area:

Yes

Area of vegetated grounds:
Performance Year Baseline Year
Vegetated grounds 37.42 Acres 239.80 Acres

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

Percentage reduction in total water use per unit of vegetated grounds from baseline:
0

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:

The University has installed over 250 bottled water filling stations on Boston-area campuses. The effort inflates the university water consumption statistics but reduces single-use plastic bottles on campus. During spring 2021, the irrigation system is undergoing an improvement to bring all controller data into a single user interface to allow better irrigation control during rain events and generate alarms when repairs are needed to irrigation components.


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

The University has historically made groundwater recharge a part of all large construction projects on campus. The use of hardscape throughout the City of Boston has reduced water infiltration considerably and water tables have dropped as water is transported away from the city through the storm water drainage systems. In more recent construction projects the university has installed permeable pavement to reduce hardscape, bio swales with indigenous plants to reduce the flow of heavy storms, and rainwater collection systems to water athletic fields and flush toilets in a research building.


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):

The University is committed to the installation of efficient toilets, urinals, faucets, and shower heads throughout campus. Automated flush and faucet valves are located throughout campus to reduce water use through excessive flushing and faucet flow.
