Toowoomba Regional Council (TRC) is reminding residents to think carefully before planting trees or large plants near their property’s water and wastewater pipes.

Smart planting can help residents avoid costly plumbing emergencies and protect vital infrastructure.

TRC’s Water Infrastructure Services portfolio spokesperson Cr Bill Cahill said tree roots growing inside and around underground pipes are one of the most common causes of damage and blockages across the Region.

“Old or cracked pipes are the perfect entry point for tree roots,” Cr Cahill said.

“Once roots grow around and inside pipes, they thrive on the moisture and nutrients, growing thicker until they completely block and damage the pipe. This can lead to expensive overflows, flooding, and repairs.”

Cr Cahill said this problem is more common than many residents realise.

“Around 60 per cent of the Region’s wastewater emergencies are caused by tree roots growing around or entering pipes and the unfortunate part is, most of these situations are preventable,” he said.

The first step to preventing issues is knowing where your pipes are located on your property.

Residents can use Council’s Online mapping (Smart maps) to find this information, or request a copy of their private drainage plans by contacting TRC’s Customer Service team on 131 872.

Cr Cahill said once residents know where their pipes are, they can take simple steps to protect them.

“Start by choosing the right plants. Ask your local nursery for advice on species with shallow or non-invasive root systems,” Cr Cahill said.

“Another great solution is installing root barriers. These are made from tough materials and can be placed around plants to stop roots spreading too far and deeply.”

“Professional advice can also be useful in preventing problems. A licensed plumber can check for early signs of root intrusion, while a qualified arborist can assess tree roots that may pose a risk.”

“We live in a beautiful region filled with gardens and parks, but our love of greenery shouldn’t come at the cost of damaged pipes and flooded homes. By planting smart, residents can protect their pipes, avoid costly repairs, and help ensure our community’s water and wastewater systems run smoothly.”
