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

The permaculture garden site in West College Courtyard has a rainwater catchment systems, which is used to supply water to the garden.

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

Wesleyan has a stated and demonstrated commitment to conserve water. In 2008, Wesleyan installed a pool cover for the main indoor pool to prevent energy loss and evaporation when the pool is not in use. In 2011, Wesleyan replaced high flow toilets, flush valves on toilets and urinals, and faucets with low flow units, reducing consumption by 13,100,000 gallons (17,565 CCF) annually.

Data source(s) and notes about the submission:

We only have a few irrigation meters, most irrigation systems are connected to building meters and city of Middletown won’t credit for submetered irrigation.

Note that differences between potable water and wastewater is approximately 125K CCF; the thermal and chilled water loops account for 119K. The rest is irrigation on Andrus Field (football fields) and at Freeman (athletic fields).
