Trees & Sewer Pipes

Trees and shrubs play an important role in our daily life. They enhance the environment while providing shade, windbreaks and aesthetic value to any home.

However, many species are unsuitable for planting near your home’s sewer pipes or Hunter Water’s sewer mains.

What trees should I avoid planting near pipes? 

  • Frequently Asked Questions

    • Where are my sewer pipes located?

      Answer

      The location of our sewermains and your pipes can be hard to identify without plans, although you can usually find an inspection shaft cover somewhere in your yard.

      We can provide you with a plan of your property showing where our sewer mains are located (which includes a fee) or contact Dial Before You Dig. A qualified plumber can provide you with a basic plan of where your sewer pipes are located.

    • How do tree roots damage pipes?

      Answer

      Some species are not suitable for planting near sewer pipes - their roots can infiltrate and eventually destroy pipes, causing significant inconvenience and costly repairs. Roots anchor and support trees, but they also seek and supply moisture and nutrients for continued growth.

       

    • What about trees causing problems now?

      Answer

      We use a special foam to inhibit root growth in sewer mains, and, in the case of your own pipes, you can get a plumber to do the same or use an electric eel. Repair and reinforcement of the affected sewer pipes is also a practical option worth considering.

      However, in severe cases you may need to consider removing the offending tree. If this is the case it is vital that you correctly identify which tree is causing the damage. You should then obtain a copy of your local council’s Tree Preservation Guidelines, as you will need their approval to remove the offending tree.
