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

WPI has a water drainage system at the Sports and Recreation Center that is designed to collect drainage water from the rooftop and perimeter of the building, channel it to one of two 25,000 gallon cisterns buried beneath the Quadrangle, and then pump it to the rooftop to resupply make-up water for the cooling tower.


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):

Waterless urinals were installed in the Sports & Recreation Center. Low-flow faucets and showers were installed in the Sports & Recreation Center, East Hall, and Faraday Hall. Toilet flushometers were installed in the Sports & Recreation Center and Faraday Hall. In building renovations, priority is placed on water conservation appliances.
