Optional Fields

A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:

n/a

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

UD employs Reverse Osmosis technology to reclaim and reuse water in some of our labs and in our campus-wide steam / chiller operations. This has resulted in tens of thousands of gallons of reductions in water consumption.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):

UD has retrofitting all Residence Halls with water sense certified low-flow (1gpm - 1.5gpm) shower heads. This is our new campus-wide standard, so all new shower heads or replacement shower heads will meet this standard.
