This document discusses using behavioral techniques to promote water efficiency in the workplace. It explains that behavioral change, rather than policy or infrastructure changes, can influence water users' habits by arranging rewarding environments or disincentives. Behavioral techniques can break wasteful water habits and create saving habits, increase engagement with efficiency, and promote wider sustainability messages. Waterwise has worked with water companies on non-household efficiency through training, awareness raising, and innovation partnerships. Current barriers to using behavioral change for water efficiency are also addressed.
