Optional Fields

A brief description of the institution's water-related behavior change initiatives:

Denison has adopted landscaping guidelines that put a preference on native plant species and landscape designs that do not require irrigation.

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

Denison uses water sourced from wells, ponds, streams, and harvested rainwater for its irrigation use. The boilers for the heating plant use non-potable well water.

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

Denison has been systematically replacing all toilets and fixtures with low flow options. Nearly 100 percent of shower fixtures are low flow. All sinks are fitted with low-flow aerators.
