Optional Fields
We have systematically retrofitted our facilities for water efficiency and engaged in education and outreach towards this end. In 2014/15 we did a research project on behavior vs. retrofit interventions in the residence hall setting.
A brief description of the institution's water recovery and reuse initiatives:
Loyola has installed permeable pavers, drought-tolerant landscaping, rain-water collection cisterns, and living rooftops that all seek to reduce and divert stormwater run-off that otherwise would enter sewer systems, requiring energy-intensive cleaning and purification processes. The cisterns connect to Lake Michigan and feed back over 10 million gallons of water annually to the Great Lakes watershed. Semi-permeable paving material is also used on campus and semi-permeable artificial turf is used on Sean Earl Field inside the track, allowing rain-water to percolate into the ground.
A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
High efficiency fixtures are standard in any retrofit or new construction. A student project identified available water retrofits in all residence halls and the Water Tower Campus. A grant provided funding to implement these retrofits as well as a test a behavior change campaign focused on water use.
