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

A brief description of the institution's water recovery and reuse initiatives:
Many parts of campus do not have installed irrigation systems.

Water trucks that are used to spot water new plantings (initially grown in the campus nursery, then transplanted) utilize non-potable water for irrigation.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:
Replacement of fixtures occurs during planned renovations. At that time, high-performance low-flow fixtures are used and are standard IU practice.
