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

The FY14 baseline was selected to align with MIT's greenhouse gas commitment.

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:
---

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

An innovative storm water retention and management system at the Stata Center employs a bioswale to capture and filter stormwater runoff. This water is harvested, filtered, and used as flushing water in the 430,000 GSF building. MIT deploys "smart metered" irrigation systems around campus to conserve water. In the central cooling plants, water is metered and monitored to identify potential water loss in the system.


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):

MIT completed many water fixture retrofits throughout campus. Ultra low-flow fixtures are the installation standard for all replacements. New construction employs LEED gold design standards, which encourage water saving strategies.
