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

2014-2015 was selected for the baseline year for this credit because historical data is not available for all of the data points required for this credit.

Optional Fields

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

---

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

All storm drainage water is directed (whenever topographical elevations permit) into three existing stormwater detention ponds, which are used as the primary irrigation source for the campus. This system does not address all of the university’s property.

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

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.
