Does the institution have retention ponds?:
A brief description of the institution's retention ponds:
Kroon Hall has a retention pond that filters the water using plants and then pumps it back into the building for reuse in building toilets.
The Sculpture building has a stormwater retention system that collects stormwater from the roof of the main 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.
