Does the institution use non-potable water (e.g., harvested rainwater or graywater) for irrigation and/or other applications?:
A brief description of the source of non-potable water and how it is used:
A number of buildings on campus harvest rainwater for uses such as flushing. Once example is the sculpture building:
A stormwater retention system collects stormwater from the roof of the main Sculpture Building and surrounding landscape which is used for flushing the toilets. The stormwater is initially stored in an outdoor 5,000 gallon tank, a size accommodates water requirements during monthly drought periods. It is then pumped into a 400 gallon indoor tank and disinfected with an ozone treatment, readying it for use in toilets. These measures ensure that the building does not add to the municipal storm water system.
