Optional Fields
Eco-Reps work to educate their peers about water conservation and host events throughout the year including competitions to take shorter showers and to use only cold water when doing laundry. Similarly, Lehigh has a faculty-staff peer-to-peer outreach program called the Sustainable Office Program. Through this program, faculty/staff are encouraged to use water reduction signage in all/majority of their certified office spaces. The University staff established water-reduction goals in 2020 to be implemented over the next five years.
A brief description of the institution's water recovery and reuse initiatives:
Unmetered local wells are used in lieu of potable city water for irrigation of most athletic fields. A new building scheduled to open in early 2022 will include a rain water harvesting system to reduce the potable water needed to flush toilets, in addition to a green roof.
A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
Low-flow fixtures are used in all new construction and major renovations, and for replacing older fixtures that fail. In August 2021, two residence halls and two academic buildings underwent plumbing-fixture retrofits to replace manually-operated higher-flow water fixtures with occupancy-sensor-operated lower-flow water fixtures.

Data source(s) and notes about the submission:
Water use was impacted by COVID-19, therefore data from FY 19 was used here to be representative of a normal year. We also used the PRE-4 and PRE_5 data from FY 19 as well to be an equal comparison.
