Smoke testing

Each year Hunter Water and our contractors complete an extensive works program to make sure water and wastewater infrastructure stays in good shape.

We have engaged a contractor, Interflow, to carry out routine smoke testing of our wastewater (sewer) system at various sites, as part of our maintenance program. The work involves smoke testing Hunter Water’s wastewater network (including sewer pipes and maintenance holes).

About the work

We will be conducting smoke testing of wastewater infrastructure located throughout Hunter Water's network.

Work involves using a smoke-fog generating machine to direct smoke into our wastewater pipelines and monitoring them to see if or where smoke comes out. The smoke-fog used in the testing is non-toxic and will disappear quickly.

This testing may help identify faulty plumbing or cracks in the system.

Locations

• Marmong Point - Nanda Street

Our work schedule

We plan to carry out the smoke testing in mid to late November 2025.

Most activity will be carried out between 7am and 5pm Monday to Friday (excluding public holidays), however the contractor may need to arrange testing of some properties on a Saturday.

What to expect

You may notice additional noise, construction vehicles in the area and some smoke-fog in both yours and surrounding properties where the sewer pipes are located and connected to each property.

Our aim is to minimise inconvenience to you and we thank you for your patience during this work.
