Stormwater + Water Use

From residential halls to laboratories, water is a key resource that supports over 20,000 faculty, staff, and students at Yale daily. Yale’s overall water demand and discharge to the sewer system can have a significant impact on the local watershed. Conserving water resources at Yale includes reducing potable water usage and mitigating the stormwater runoff generated during rain events.

To meet its potable water reduction goal, Yale is currently in the process of implementing a three-year Water Management Plan for continuous improvements in water use in buildings, power plants, and irrigation systems.

Campus water use provides an opportunity for student research as well as a place to experiment with new technologies and infrastructure. Yale has set a goal to reduce potable water use on campus 8% below 2012 levels by June 2016.

In addition to reductions in wastewater, Yale’s large campus also has the opportunity to mitigate a significant source of pollution to four local water bodies. Stormwater runoff produced during rain events enters the sewer system and discharges directing into local waters or combines with sewage and is potentially dumped untreated into the Long Island Sound. Yale’s Stormwater Management Plan outlines strategies to address those issues, including green infrastructure projects such as rain gardens and urban meadows.
