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:

The Washington Quad, surrounded by residence halls, now features a stormwater irrigation system. A 10,000 gallon cistern receives stormwater from the roofs of the surrounding buildings. A computer controlled system then directs the water to a drip irrigation system to the plant beds nearby. The system eliminates the need to water all the planted beds during warm periods.

Knight Hall, home to the school of Journalism, is a green building surrounded by green space that now captures the rain that falls on the site in a 10,000 gallon cistern buried under the courtyard. This system collects rainwater from roof drains, channels the water through a high capacity filter in the courtyard, and stores it in an underground cistern. A drip irrigation system detects the amount of moisture in the soil so that plants are only watered as needed. When the irrigation system calls for water, pumps send water from the cistern through the irrigation system for distribution on-site.
