Wastewater

A property owner is responsible for repairs and maintenance of the wastewater pipe between the building and its public main connection. This part of the drainage system, known as the lateral, belongs to the property owner.

Wastewater pipes have a lifespan of about 80 years, and are designed to withstand normal tree root and traffic loadings. Age is often a factor when pipes become blocked or seep.

To find out what is causing a pipe problem, you should call a plumber or, alternatively, you can call the Council to request a maintenance inspection of the public mains. The owner is liable for any repair costs on their pipe.
