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:

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

19th and Vine Parking Garage is testing a new porous concrete on the parking lot. Its a product that enables water to percolate through the concrete and into the soil. Water that runs off the top deck of the parking structure drains directly into a landscaping area on the east side of the garage. And, drains from the other three decks funnel water into a specialized device that separates debris from the water.

There are 2 hydrodynamic separators on city campus in the 19th & Vine parking garage and 14th and Avery.

Morrison Center has a bioswale that recovers water from the parking lot and filters it.

Keim Hall employs 2 bioswale methods to recover and treat stormwater from their roof and Center St.

East Memorial Mall and Love Library North both use Silva Cells and permeable pavers to capture runoff.


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):
