3.3 Systems for water recovery and return
Narrative and/or website URL providing an overview of the institution’s on-site rainwater harvesting systems:
Our Science Center does capture and use rainwater as part of its RO/DI system in the building. We had originally intended for the collection system to also fill the cooling towers at the central plant, but that has not happened.
Simiarly, our Greenway residence halls were designed to capture rainwater and reuse it for flushing toilets. However, we have struggled with this from the beginning. There were many maintenance issues, leaks, pumps failing, etc. Although we have the ability to capture rainwater, the system is currently offline and not being used.
Does the institution recover water on-site for reuse?:

Does the institution collect and return water to surface water or groundwater through on-site green infrastructure?:
Narrative and/or website URL providing an overview of the institution’s on-site green infrastructure:
Our three most recent buildings (Science Center, Greenway Residence Halls, Lyceum) all have built in rain gardens, designed to collect runoff from surrounding hardscape and allow this runoff to soak into the ground instead of washing away. Each rain garden is located adjacent to the buidings and are planted with plants, trees, and bushes that can survive in waterlogged environments.
The Science Center includes a Green Roof which provides habitat for a variety of plant, animal, and insect species, retains precipitation thereby reducing runoff, and helps regulate the building's indoor temperature.
The Reporting Tool will automatically calculate the following figure:
3.4 Ratio of water recovered/returned to total water withdrawal
