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:

Some toilets in the Campus Center and Milas Hall are designed to save water by using different amounts of water when needed and have the appropriate signage.


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

Olin College invested in the water efficiency and wastewater planning from its original construction. Seventy percent of the irrigation systems on campus are fed by well water.


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):

Olin has begun upgrading flushometers for the toilets in dormitories in order to make them low-flow toilets. They are Water Sense certified by the EPA. Faucets are also being upgraded in the dorms to low flow Water Sense certified. Shower heads are also being replaced so that they are low-flow.

Level of risk was determined using the Water Risk Atlas: http://www.wri.org/applications/maps/aqueduct-atlas/#x=-71.27&y=42.21&s=ws!20!28!c&t=waterrisk&w=def&g=0&i=BWS-16!WSV-4!SV-2!HFO-4!DRO-4!STOR-8!GW-8!WRI-4!ECOS-2!MC-4!WCG-8!ECOV-2!&tr=ind-1!prj-1&l=11&b=terrain&m=group

Olin's water meter data was used to calculate potable water usage and the well water usage was estimated based on run time and flow rate of the well.
