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:

Our education programs and outreach such as Green Office Certification and Eco-Ambassadors include water use reduction. We often give staff prompts to remind people to conserve water at the sink.
We do a lot of education around the negatives of bottled water and encourage students and employees to use reusable water bottles. For people planning events, we assist them with water pitchers rather than bottled water.


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

Tufts uses condensate from purchased steam to replenish a cooling tower water in lieu of using city water. This is for the Tufts Shared Services plant on our Boston campus.


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):

Any time any water fixture is replaced at Tufts we use a water efficient appliance (e.g. low-flow showerhead, faucets, and toilets). Often dual-flush toilets are used, but not in the residence halls.

Cage and rack washer at DLAM upgraded to a water-efficient washer.

Much of Tufts' water conservation efforts took place prior to 2005 and therefore are not captured using this metric.

For the FY18 data reported here, we were able to calculate additional water use from non-metered wells used for irrigation of Tufts' Alumni Fields. We added that to the total potable water use at the university. The total non-potable water estimated to come from these wells is 2,649,600 gallons per year. These non-metered wells were drilled after the baseline year of 2005.
