A brief description of when and why the water use baseline was adopted:
Water recycled/reused on campus, performance year:
Recycled/reused water withdrawn from off-campus sources, performance year:
A brief description of any water recovery and reuse systems employed by the institution:
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 separator 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 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.
