A brief description of any water recovery and reuse systems employed by the institution:

19th and Vine Parking Garage is testing a new previous concrete on the parking lot itself. 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.
A Hydrodynamic separator in the parking garage acts as a large storage tank that separates derbies and pollutants from the water.

UNL's newly renovated Keim Hall captures rainwater which then waters plant surroundings the building and helps supply the new pond and waterfall in the building's courtyard.

A brief description of any water metering and management systems employed by the institution:

Buildings at the University are metered by Lincoln Water System. UNL installed additional meters at seven different campus buildings enabling the Energy and Automation team to review water usage on an hourly basis at those locations.

A brief description of any building retrofit practices employed by the institution, e.g. to install high efficiency plumbing fixtures and fittings:

A brief description of any policies or programs employed by the institution to replace appliances, equipment and systems with water-efficient alternatives:

A brief description of any water-efficient landscape design practices employed by the institution (e.g. xeriscaping):

UNL uses a variety of native and drought-tolerant plants as a practice for reducing water consumption.

A brief description of any weather-informed irrigation technologies employed by the institution:

Landscape Management irrigation team designs, installs, and maintains irrigation system campus wide. Numerous rain data collectors have been installed throughout campus. These collectors are connected to the system’s computers and control the amount of water irrigated based on rain levels.
