Optional Fields

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

Lafayette has implemented several water-related behavior change initiatives in the past couple years. LEAP placed small signs with song lyrics about water and "turn off when not in use" language around public bathroom faucets.
During the Spring of 2019, the Student Government Sustainability Committee campaigned for shorter showers in the Residence Halls by placing signs with facts on water use and limiting showers to 2-3 songs (as many students have expressed that they listed to music in the shower). The Committee also made fun shower playlists with sustainability related songs to encourage mindful water use.

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

Lafayette employees a rainwater collection system on the roof of an operations building to feed into the irrigation of our 3 acre organic farm.

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

Low-flow shower heads, sinks, aerators, and toilets are the standard when renovating bathroom.
Preventive maintenance is conducted on steam traps and steam lines are monitored for leaks and replaced when discovered.
Preference is given to native drought resistant plant species to reduce the necessity of irrigation.
