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

We chose 2008 as our Baseline year to match the entries for Energy, and Waste.

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:

Dining Services recycles water squeezed from its post-consumer food waste (through a SOMAT) and re-uses it on the conveyor and first dish rinse; then it's released to an on-site waste water treatment plant.


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 flow rating on campus shower heads is 2.0 gallons per minute (gpm). The U.S. Department of Energy identifies a “low flow” shower head as any fixture that is at or less than 2.5 gpm. On aerators for new sinks, the College is installing fixtures that use 2.2 gpm (which is the minimum requirement for a low flow faucet). All new toilets are rated at 1.6 gallons per flush (consistent with the average low flow toilet).
