A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:
---

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

Elon's automatic irrigation system is supplied with reclaimed stormwater. A significant amount of stormwater from Elon's campus is directed into three man-made ponds on campus, and these ponds are then connected to the irrigation system. This system is beneficial to the local watershed in that it prevents sediment and other materials from entering nearby natural waterways.


A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):

Over the last several years, the university has replaced most toilets and shower heads with low-flow models. Low-flow faucet aerators have been installed in most lavatory locations and all commercial kitchen facilities.
Construction standards for new, retrofit and renovation projects include low flow plumbing fixtures for faucets, urinals and toilets.
