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Recycled/reused water withdrawn from off-campus sources, performance year: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:
LIU Post manages its storm water runoff by capturing it in drywell systems or by diverting it into retention areas on campus. There is a system of approximately 300 drywells and six drainage retention areas that are used to control storm water runoff of all the buildings and parking areas on campus.
A brief description of any water metering and management systems employed by the institution:
All domestic water is metered. Jericho Water Authority is the local provider for all domestic water. There are meters at several locations on campus. LIU Post also uses well water that is metered to irrigate several athletic fields.
A brief description of any building retrofit practices employed by the institution, e.g. to install high efficiency plumbing fixtures and fittings:
Most of the toilets, urinals, and lavatory sinks at LIU Post have been retrofitted with low-flow fixtures, flushing devices and faucets.
A brief description of any policies or programs employed by the institution to replace appliances, equipment and systems with water-efficient alternatives:
Most kitchen, lab and other equipment at LIU Post are replaced with more efficient systems during renovations.
A brief description of any water-efficient landscape design practices employed by the institution (e.g. xeriscaping):
Depending on the location, xeriscaping is used. An example of this is using Prickly Pear Cacti (Opuntia) in our gravel beds. Also, ornamental grasses such as Pampas Grass (Cortaderia Species) are used around the campus grounds. Some areas on campus also use bamboo to provide erosion control and screening.
A brief description of any weather-informed irrigation technologies employed by the institution:
All automatic irrigation systems at LIU Post have rain sensors and some have additional sensors for wind speed and temperature. All systems are then monitored on a regular basis and adjusted as necessary. Night and early morning irrigation is most often used. Conditions on the Athletic Fields are used in connection with the weather forecast to set parameters for the sensors. All water output is metered and logged.
A brief description of other water conservation and efficiency strategies employed by the institution:
The Department of Facilities Services at LIU Post attempts to put forth the best water efficiency program by ensuring that all water-consuming equipment is operating properly. Therefore, Facilities Services continuously monitors all water-consuming equipment and repairs and/or replaces any defective equipment in order to prevent excessive use of water discharges.
