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

Albert Sherman Center is designed to reduce potable water consumption, by collecting and reusing non-potable water. Nonpotable water can be collected from the following three sources (1) RO Reject, (2) AHU Condensate, and (3) Rainwater. At this time, these collection features are not being used.

The RO Reject is utilized by the vivarium cagewash equipment. The AHU Condensate and the Rainwater is sent, via a campus greywater collection system, to the power plant for use as the cooling tower make-up water. While not separately metered, modeling predicts the reduction in overall potable water use to be 3,245,956 gallons per year.

NOTE: grey water collection calculations were competed by Bard, Rao, and Athanas consulting Engineers, LLC as part of the Albert Sherman Center's LEED certification process.

Data source(s) and notes about the submission:

The vast majority of UMass Chan's potable water stems from the power plant and landscaping accounts for about 5% of UMass Chan's water use.

Note: the teaching hospital's water use, while outside of the boundaries of the rest of this report, is included in the total potable water count.
