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

UVa has several cisterns that collect water for use at both times of draught and for landscaping establishment and gardening purposes. Since those cisterns are not metered, the rainwater collected and subsequently reused is not included in the totals above.

The University has also installed multiple condensate recovery systems. These systems captures air handler condensate (the liquid product of dehumidification) and sends it to our chiller plants for use in the cooling towers. Generally these systems recover under 2 million gallons a year.

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

EPA Water Sense fixtures are required for all new projects and in-kind replacements. LEED certification of new construction, major renovations and large interior fit outs is required. These projects are often use ultra-low consumption to maximize their LEED rating.
