A brief description of when and why the water use baseline was adopted:

The water baseline was established in Miami's 2010 Sustainability Commitments and Goals.

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Recycled/reused water withdrawn from off-campus sources, performance year: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:

Miami harvests rainwater as well as A/C condensate for irrigation of Cook Field
o At Cook Field and adjacent areas we harvest 25 acres of run off into two new storm water runoff control and detention ponds that are in turn used to irrigate playing fields. In addition to this we harvest A/C condensate in the summer from Western Campus residence halls to the same pond. See pages 58-63 of the stormwater master plan online for more details. https://pfd.muohio.edu/projects/SWMO.pdf

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

The city installs and reads all building water meters on campus. Most buildings are individually metered.

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

Low flush and flow plumbing fixtures are in use throughout the University. They have been installed either through LEED construction projects or through ongoing maintenance projects.
Touchless faucets have been installed in residence halls, dining halls, and kitchens to reduce the amount of water wasted.

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

As heat pump chillers coupled with ground source geothermal well fields increase in use on the campus, there will be less cooling load supplied by the campus's chiller plants, and therefore less water evaporated by cooling towers. Initial phases and supporting infrastructure are in various stages of completion and use. By the time of full implementation in 2025, an estimated 16 million gallons of cooling tower water will be saved annually.

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

Perennial Gardens of native plantings, once established, require minimal watering and weed control. These are installed in various campus locations on main and Western campus. Western campus also has a field of native prairie grass. A list of native landscape plantings is included in Maimi's stormwater master plan. https://pfd.muohio.edu/projects/SWMO.pdf

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

A brief description of other water conservation and efficiency strategies employed by the institution:

Miami's new standard water softener does not use salt, and does not require back-washing, saving a considerable amount of water.
Make-up water is saved in the steam system by regularly-scheduled steam trap maintenance.

The website URL where information about the institution’s water conservation and efficiency initiatives is available:

Non potable water was estimated as follows.
Baseline year: 2 soccer fields each 200' x 360' were irrigated with surface water supplemented with potable water (assume 1/3 is potable). Estimate 10 weeks of watering at 0.623 gallons/square foot, the amount needed to provide 1 inch.
Performance year: The soccer fields above, plus the natural turf portion of Cook Field, 200,000 square feet, were irrigated with surface water. Use the same assumptions as the soccer fields.
