Let's talk: Odour at North Head


North Head Wastewater Treatment Plant is the second largest of the wastewater treatment and water recycling plants in greater Sydney, the Blue Mountains and the Illawarra.

We know that some odour is involved in the work we do. If odour from the plant is a problem for you, please use our mapping tool to help report it.

This will help us understand how odour impacts you.
