Take a walk around your worksite and look for any areas where water is leaking or being used unnecessarily.

The issues you find could include dripping taps, leaking connections, inefficient sprinkler systems, or even work practices that use excessive water.

Describe the problem and the best way to fix it. Who would you report this problem to?
