Stormwater drains play a critical role in directing rainwater away from your property, preventing flooding and water damage. However, tree roots can invade these systems, causing blockages and extensive damage. In this blog, we’ll explain why tree roots are a problem for stormwater drains and how to address and prevent the issue.
How Tree Roots Invade Stormwater Drains
Tree roots naturally seek out water and nutrients to support their growth. Stormwater drains provide the perfect environment for roots to thrive. Here’s how roots invade your plumbing system:
- Small Cracks in Pipes: Roots enter through small cracks or joints in older pipes.
- Growth Over Time: Once inside, the roots grow and spread, worsening the blockage.
Complete Blockages: Left unchecked, the root mass can completely obstruct water flow, leading to flooding and drainage problems.


Signs of Tree Root Intrusion
Early detection is key to preventing extensive damage. Look out for these warning signs:
- Slow Draining Water: Water takes longer to drain from outdoor grates or gutters.
- Pooling Water: Rainwater collects around your property instead of draining away.
- Unpleasant Smells: Foul odours near stormwater drains may indicate decaying organic matter.
- Recurring Blockages: Persistent blockages are often caused by roots in the system.

Real Case Study: Tree Root Intrusion in Stormwater Drain – Ringwood VIC
Problem:
A homeowner in Ringwood noticed water pooling in their driveway every time it rained. Over time, the problem got worse, and they started smelling a foul odour near the outdoor drains. After trying basic cleaning with no success, they called in Pro-Action Plumbing for help.
Solution:
Our plumbing team in Ringwood Vic began with a CCTV camera inspection and found tree roots growing deep inside the stormwater pipe. The roots had entered through a small crack and were now blocking the flow of water. Using high-pressure water jetting, we removed the root mass completely. Since the pipe had some damage, we also installed a pipe liner to seal the inside and stop roots from getting in again.
Outcome:
The drainage system was restored, and the water flowed away properly again. The bad smell disappeared, and the property was no longer at risk of flooding. The homeowner was relieved to have the problem fixed without any digging, and they were happy knowing the pipe was now protected for the future.
Conclusion.
Tree roots can cause big problems for your stormwater drains, especially if you live in Melbourne’s Eastern Suburbs. When roots get into the pipes, they block the water and can lead to flooding, bad smells, and costly damage. The good news is, that with the right help, you can fix the problem and stop it from coming back.
