Extreme weather is becoming more frequent, and the CSIRO points out that short bursts of intense rainfall have increased by at least 10% in some areas. The ARC Centre of Excellence for Climate Extremes warns that these heavy downpours can lead to flooding and major issues—especially when other factors, like blocked drains or saturated ground, come into play.
Don’t let a small leak fool you—what starts as a trickle can quickly turn into a pricey problem. Ignoring it could mean damage to walls, floors, or foundations, leaving you with steep repair bills. You’ll also notice a spike in your water bill and the environmental impact of all that wasted water. And with utility costs on the rise, that’s an expense you definitely don’t need.
Common Signs of Stormwater Drain Leaks
Leaking stormwater drains can be a nightmare for homeowners, leading to everything from cracked foundations to expensive repair bills. Spotting the early signs of a leak can save you a lot of headaches (and money) by preventing bigger issues down the track.
Visible Indicators of a Leaking Stormwater Drain
If you notice pooling water around your property after a heavy downpour, it could be a telltale sign of a stormwater drainage issue. Look out for standing water near stormwater grates, drainage pits, or pipes—this often points to a blocked drain.
Other red flags include unexplained damp patches on your lawn, water puddling around drain pipes or slow drainage near storm drains. Cracks in concrete or driveways might indicate erosion caused by leaking stormwater systems. Overflowing gutters and sudden mould growth near underground pipes are also clear indicators that something’s off with your drainage.
Subtle Signs of Stormwater Drain Leaks
If you catch a foul smell around drainage areas, it’s often a sign that you’re dealing with a blocked stormwater drain or clogged pipe. Strange gurgling noises coming from blocked stormwater pipes, the shower drain, or roof gutters usually point to minor blockages that could turn into bigger problems if ignored.
Slow drainage in the stormwater system can cause water to overflow, while a sudden spike in water usage might hint at a hidden leak in the drainage system.
Consequences of Ignoring Leaks
Ignoring stormwater blockages and leaks can spell trouble, leading to soil erosion, structural damage, and even flooding during heavy rain. Tree roots, leaves, and other debris—sometimes even food scraps—can clog up drains and pipes, creating damp conditions that are perfect for mould growth.
Blocked stormwater drainage can also cause excess water to spill over, potentially harming local waterways and damaging your property.
Causes of Stormwater Drain Leaks
Knowing what causes leaks in your stormwater drainage system can save you from expensive repairs and the headaches that come with property damage. Here’s a closer look at the most common culprits behind stormwater drain leaks—and what you can do about them.
Tree Roots Infiltrating Pipes
One of the main culprits behind stormwater drain blockages is root intrusion. Tree roots are naturally attracted to the moisture inside stormwater pipes, and over time, they can work their way into underground pipes, leading to blockages and slow drainage.
Regular maintenance is key to catching minor root issues before they become major headaches. Using a high-pressure water jet or a drain auger is an effective way to clear blocked pipes and keep things flowing smoothly.
Old or Degraded Materials
Many older homes have stormwater drainage systems made from outdated materials that can break down over time. Cracked pipes and worn grates can cause blocked drains, damp patches, and water pooling around the property. Instead of replacing the whole system, pipe relining offers a more affordable fix. It’s a good idea to have a licensed plumber inspect your drainage regularly to catch small issues before they turn into bigger (and more expensive) problems.
Heavy Rains Overwhelming the System
During heavy rain, stormwater drainage pits and roof gutters can overflow, causing excess water and blocked drains. If a stormwater drain gets clogged early in a downpour, it can quickly lead to serious flooding and plumbing headaches.
Regular maintenance—like clearing out leaves, debris, and even food scraps—can help prevent flooding and keep water flowing smoothly through your drains.
Improper Installation or Poor-Quality Materials
Poor installation or using cheap materials can lead to all sorts of stormwater drainage problems. If you notice clogged drains, strange gurgling noises, or foul smells around drain pipes, it could be due to a shoddy installation.
Hiring a professional plumber to handle the installation or repairs can prevent blockages and make sure your system works like it should.
Structural Shifts in Soil
Changes in weather or nearby construction can cause soil to shift, which might damage stormwater pipes and lead to blockages or slow drainage. These shifts can also crack pipes, resulting in water pooling or runoff into local waterways. Regular inspections can catch potential issues early and prevent further damage to your property.
Having a licensed plumber routinely check and clear your stormwater pipes can keep your drainage system in top shape, saving you from expensive repairs down the line. Plus, if you’re unsure about maintenance, your local council might have helpful advice on keeping your property safe during heavy rain.
DIY Checks Before Calling a Plumber
Doing a few simple DIY checks on your stormwater drains can help you spot potential blocked stormwater drain early before they turn into bigger problems. Here’s what you can do:
Inspect Outdoor Areas
Begin by checking the outdoor areas around your property for signs of a blocked stormwater drain. Keep an eye out for water pooling near drainage pits, grates, or along stormwater pipes. Damp patches or standing water can hint at a blockage or leak. You should also look out for tree roots or structural damage around underground pipes, as these could be behind your drainage issues.
Test Water Flow During Light Rains
When it’s raining lightly, take a moment to see how water moves through your drainage system. If you notice slow drainage or water pooling around storm drains, gutters, or pipes, it could be a sign of a blockage. Listen for gurgling noises coming from pipes or gutters—these sounds often mean there’s a minor blockage that could turn into a bigger problem if left unchecked.
Remove Visible Debris
Clearing leaves, food scraps, and other debris from stormwater grates, roof gutters, and drain pits can go a long way in preventing blockages in your drainage system. Make sure nothing is blocking the flow of water in runoff areas. If you notice slow draining or a blocked water drain, it could be a sign of a bigger issue like root intrusion or a major blockage.
While these DIY checks are great for spotting minor problems, it’s important to call in a qualified plumber for accurate diagnosis and repairs. Serious issues like stubborn blockages, slow drainage, or structural damage should be tackled using professional tools like high-pressure water jets, drain augers, or pipe relining. If heavy rain or a drainage problem is making you worry, getting help from a professional can prevent costly property damage and ensure your stormwater system is ready to handle whatever comes its way.
Professional Stormwater Drain Leak Repairs
When stormwater drainage issues get tricky, calling in the pros is the best way to get things sorted out quickly and accurately. Licensed plumbers use modern techniques like CCTV inspections, hydro jetting, and pipe relining to fix drainage problems without tearing up your property.
CCTV inspections involve inserting a small camera into stormwater pipes to spot blockages, leaks, or damage. This allows plumbers to pinpoint exactly where the issue is and what’s causing it. Hydro jetting, or high-pressure water jetting, blasts away blockages, debris, and clogged drains, restoring water flow without damaging the pipes.
Pipe relining is another advanced solution where a durable lining is inserted inside the pipe to seal cracks and stop leaks—no need for disruptive digging or excavation. These modern methods not only minimise property disruption but also help keep repair costs down.
It’s important to hire experienced plumbers who know Brisbane’s stormwater infrastructure and regulations inside out. Local pros understand the unique challenges of Brisbane’s heavy rainfall and stormwater runoff, so they can ensure repairs are effective, compliant, and tailored to the area’s needs.
Preventative Measures to Protect Your Stormwater System
Taking a few simple preventative measures can go a long way in keeping your stormwater system healthy and saving you from expensive repairs down the line.
- Schedule regular maintenance checks: Have a professional plumber do routine inspections to catch minor blockages or leaks before they become big problems.
- Be mindful of what you plant: Avoid planting trees or plants with invasive roots near stormwater pipes, as roots can easily cause blockages and structural damage.
- Install gutter guards: Gutter guards help stop leaves and debris from clogging up your roof gutters and drainage pits, reducing the risk of blockages.
- Check your drainage slope: During installations, make sure your drainage system has a proper slope to promote smooth water flow and prevent pooling or slow drainage.
Preventative maintenance is always cheaper and easier than dealing with major plumbing issues or property damage. Regular care can help you avoid flooding, reduce blockages, and keep your stormwater system working like a charm.
