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

Water recycled/reused on campus, performance year:

Recycled/reused water withdrawn from off-campus sources, performance year:

A brief description of any water recovery and reuse systems employed by the institution:
The Living Machine treats and internally recycles water in the Adam Joseph Lewis Center.

A brief description of any water metering and management systems employed by the institution:
Oberlin's Campus Resource Monitoring System provides real-time monitoring of water use in nineteen residence halls.

A brief description of any building retrofit practices employed by the institution, e.g. to install high efficiency plumbing fixtures and fittings:
Low-flow toilets, urinals, and shower heads have been installed in many places across campus. Additionally, efficient faucet aerators have been installed.

A brief description of any policies or programs employed by the institution to replace appliances, equipment and systems with water-efficient alternatives:

A brief description of any water-efficient landscape design practices employed by the institution (e.g. xeriscaping):
Plants are seldom watered. Spot watering is done only as an emergency. Native plants are featured in several prominent locations on campus. The Adam Joseph Lewis Center for Environmental Studies was conceived as an integrated building-landscape system. The landscape features a variety of constructed ecosystems that simulate native Northern Ohio ecosystems and incorporate cultigens that produce food for humans. The restored wetland and forest ecosystems speak to the pre-agricultural history of the site. The George Jones Farm also includes preserved forests and restored wetlands.

A brief description of any weather-informed irrigation technologies employed by the institution:
All irrigation systems have moisture sensors that automatically adjust irrigation.

A brief description of other water conservation and efficiency strategies employed by the institution:
The Community-Based Social Marketing (CBSM) research group is looking at ways to reduce shower times. Various shower timers and showerheads have been identified and will be installed for further testing to see if they are effective and which ones impacted behavior. If successful, these technologies will be spread across campus.
