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

The water use baseline was adopted for Fiscal Year 2018 (2017-2018) as this was the baseline utilized for the majority of our reporting.

Optional Fields

A brief description of the institution's water-related behavior change initiatives:

In partnership with the Student Government Association, stickers were placed in bathrooms and other areas with faucets that read "Water is Precious...". These stickers were designed to alter individual and collective water behavior and serve as a reminder to students, faculty, and staff that water conservation is important in day-today activities.

A brief description of the institution's water recovery and reuse initiatives:

UNCW uses several stormwater retention ponds to store irrigation water for the campus. Pump systems are tied together for water movement to different locations as needed. Oftentimes the water from the stormwater retention ponds is recycled and utilized in on-campus landscaping through the sprinkler system.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

The University of North Carolina at Wilmington (UNCW) partnered with the energy service company Ameresco to conduct an investment-grade audit of campus facilities that identified potential energy efficiency measures (EEMs). Twenty-four EEMs were selected and are under consideration to be implemented between 2012 and 2013. This project is the second performance contract for UNCW and focuses on the remaining large, general- funded buildings not included in the first contract. These government-owned buildings are funded through State appropriations. A select number of EEM's involved initiatives surrounding water use.

Additionally, several buildings at UNCW are Leadership in Energy and Environmental Design (LEED) certified, meaning that they have strides in building with water efficiency in mind. For example the Student Recreation Center is LEED BD+C Certified and was awarded 4/5 points for water effeciency (Water effecient landscaping - reduce by 50%, Water effecient landscaping - no potable water use or no irrigation, water use reduction - 20% reduction, and Water use reduction - 30% reduction).
