A brief description of the institution's water-related behavior change initiatives:
Some residence halls have included signage and done other programming to encourage occupants to reduce shower time, brush teeth without running water and take other small, easy steps to conserve water. A few wet labs also encourage water conservation by various means, but no formal, central campaigns recur.
A brief description of the institution's water recovery and reuse initiatives:
Rainwater is collected then organically & mechanically filtered, treated, and stored at Kelley Engineering, in a 16,500 gallon chemical-free cistern system. This system is used to flush toilets and urinals rather than using potable water. OSU currently does not have any reuse activities.
A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
High efficiency restroom fixtures are the campus standard. Additionally, the Sustainability Office has retrofitted hundreds of sinks with 0.5 GPM aerators.

Data source(s) and notes about the submission:
The figure used for square footage was changed to reflect Corvallis area operations, not university totals, which have been used in the past. Water data is not gathered from each statewide operation, making the Corvallis area square footage a more relevant boundary.
