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

2009 is the first year that Bentley has reliable and accurate water data collection. This was due to improved metering and process.

Optional Fields

A brief description of the institution's water-related behavior change initiatives:

We advertise to students that they should put in work orders to report leaks through Residence Life.

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

---

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

Each summer, one residence hall is renovated. Low flow bathroom faucets, shower heads and dual-flush toilets are installed in every bathroom and kitchen. All of these fixtures use half the water that standard fixtures use without compromising water pressure.

The university installed waterless urinals in the multipurpose arena.
