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:
---

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):

Low flow technology for showers and faucets as well as dual flush toilets are installed whenever the current fixtures need to be replaced or repaired.

Beginning in 2005 Amherst College started its conversion from standard shower heads (4 gallons/minute) to low-flow aerating shower heads (1.5 gallons/minute) in the athletic facility and in some dormitories.

The College supplies washing machines in each of the dormitory buildings throughout the campus. During the summer of 2005, all of the conventional washers were replaced with energy-saving/water-conserving front-loading washing machines.The new machines use 11 gallons less water per wash and use only 1/2 the amount of detergent while increasing the load capacity by 30%. In addition, the washers extract 33% more water from each load, thereby reducing drying time, which in turn saves energy. The new washers are estimated to save approximately 580,000 gallons of water per year throughout the campus.

We have begun reclaiming water in the greenway dorms and with the soon to finish science center - those will be added to the next report
