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

The Eco-Reps, our peer educator student group, works with their respective house members to educate on water conversation and the importance of it. In the past, they've held events such as April Showers, which is a water-saving competition held during Earth Week in April. Eco-Reps distribute 5 minute shower timers and challenge students to limit their showers to only 5 minutes, and to re-think if they need a daily shower. The house that records the most showers that were limited to 5 minutes or less (per person) receives a prize.

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

Our grounds management department is currently in phase 1 of a 3 phase project to update the Campus irrigation systems to increase water efficiency and effectiveness. The project includes implementing new controllers, flow meters, moisture sensors, and rain sensors. A description of each measure is as follows:

1. controllers: state of the art irrigation controllers that use all the latest technology to help manage water use more effectively

2. flow meters: installation of flow meters will account for an accurate measurement of gallons used, specifically for outdoor irrigation

3. moisture sensors: this technology sensors moisture content in the root zone and adjusts irrigation applied to the area based on that measurement.

4. rain sensors: the prevention of sprinklers running during or just after any level of rainfall. The sensors stop pre-scheduled irrigation when it detects a pre-set level of rainfall. This automatic process ensures landscapes aren't watered during a storm.
