10 Stormwater Maintenance Tips – Are You Flood-Ready?

Need some stormwater maintenance tips? If your instinctive answer is ‘no’, cast your mind back to the devastating Queensland floods of 2025 – and the images none of us will ever forget. Cars underwater, suburbs cut off, homes turned into islands overnight – they were scenes that were a harsh reminder of:

• How fast water can move
• How destructive it becomes
• And how vulnerable we are when stormwater systems fail.

So while we can’t control the weather, we can control how prepared our properties are.

That’s why stormwater maintenance tips matter more than ever these days. Because on a small scale, storm resilience starts at home. Protecting the people and things you value most – your home – means paying attention to what happens under your lawn, around your roofline, and inside the heroic pipes that quietly carry thousands of litres during every single downpour.

We’ve put together the most important stormwater maintenance tasks Brisbane homeowners should be doing – plus the signs that tell you when it’s time to call in a professional or even rethink your entire stormwater layout.

1. Clean your gutters and downpipes regularly

Leaves, sticks, silt – they all clog gutters very quickly. That’s especially true across Brisbane’s leafy suburbs and during storm season – when gutters overflow, water spills down walls, floods footpaths, and overwhelms your stormwater pipes.

What to do:

• Clear gutters every 3 months
• Make sure downpipes aren’t blocked or slow to drain
• Check for sagging sections or leaks.

It’s simple work, but huge protection.

2. Keep stormwater drains clear of debris

This is the most basic but often the most ignored part of stormwater system maintenance. Backyards, driveways, and patios collect leaves, dirt, bark, and grass clippings. And all of it ends up in the stormwater system.

What to do:

• Clear grates weekly
• Remove garden debris from around drain openings
• After storms, check for silt build-up

Did you know blocked grates are one of the top causes of backyard flooding?

3. Check your yard’s water flow (Natural drainage matters)

Take a walk around your yard after decent rain and ask yourself:

• Does water pool beside the house?
• Does it sit near the back fence?
• Is it running toward your home instead of away from it?

Many drainage problems aren’t inside the pipes – they’re in the yard itself.

What to look out for:

• Soggy patches
• Erosion channels
• Water sitting for more than an hour after rain
• Sloping that directs runoff toward your home.

This is often the first sign you’ll need professional help or a stormwater redesign.

4. Inspect your stormwater pit or inlet

Some homes have stormwater pits – older properties especially, and there are plenty of those across Brisbane and beyond. These pits catch runoff before it enters the underground pipes.

Maintenance includes:

• Removing leaves
• Clearing built-up sediment
• Checking for cracks around the pit edges
• Making sure water is flowing freely into the connected pipe.

If your pit fills quickly in light rain, that’s a sign of obstruction deeper inside the system.

5. Keep trees and roots away from stormwater lines

Brisbane’s clay pipes and older PVC lines are just like magnets for tree roots. Once they get inside, they expand fast and choke the entire stormwater system.

Prevention tips:

• Avoid planting large trees near stormwater lines
• Trim invasive roots annually
• If you have ongoing blockage issues, get a CCTV inspection.

Remember: Root intrusion is one of the biggest reasons homeowners need major stormwater repairs.

6. Have your stormwater pipes jet-cleaned every 1-2 years

This is the big one that most people skip because it seems like preventative overkill – but high-pressure water jetting is the backbone of proper stormwater maintenance. It removes silt, sand, roots, gravel, and built-up sediment that normal cleaning can’t touch, and you definitely don’t need to wait for a hopeless blockage to get it done.

It’s perfect for suburbs like:

• Logan
• Moreton Bay
• Brisbane Northside acreage homes
• Redland areas are prone to heavy leaf fall
• Brisbane Southside properties with clay soils.

Write down the catchphrase: A clean pipe is a flood-resistant pipe.

7. Use CCTV drain inspections to check pipe health

If you’ve never seen inside your stormwater system, you’re flying blind. A CCTV inspection shows:

• Cracked pipes
• Collapsed sections
• Intruding roots
• Incorrect slopes
• Blockages deep inside the line
• Debris trapped near the street connection.

This is one of the most valuable stormwater system maintenance tips because it prevents expensive surprises.

8. Know when it’s time for professional help

Some stormwater tasks are DIY-friendly. But if you notice any of the following, it’s time to call a specialist:

• Repeated blockages
• Water pooling near your home
• Stormwater overflowing during moderate rain
• Strange smells from drains
• Loud gurgling
• Water backing up from pits or grates
• Flooding around hard surfaces.

These signs usually point to deeper issues – collapsed pipes, root damage, incorrect fall, or blockages too far down the line for at-home tools.

9. Consider upgrading your stormwater system (Many homes need it)

Brisbane has thousands of properties with stormwater systems built decades ago – long before our population boom and long before today’s intense rainfall patterns.

Modern upgrades include:

• Replacing broken clay or undersized pipes
• Re-routing stormwater away from vulnerable areas
• Installing new drainage pits
• Adding surface drains or channel drains
• Fixing incorrect slopes
• Installing backflow prevention
• Designing full new stormwater drainage solutions for flood-prone yards.

Sometimes the safest option isn’t maintenance – it’s improvement.

10. Don’t ignore minor drainage problems

Small issues become big floods. A tiny trickle near the wall? A bit of water around the drain? A grate that always clogs? Think of them not as little problems you can ignore, but clear warning signs. The sooner you act, the less damage (and cost) you face later.

Stormwater maintenance saves homes – Literally

Put it this way – Brisbane’s weather isn’t getting milder, is it? Storms definitely aren’t getting weaker, that’s for sure. Staying ahead of the next downpour starts with simple, smart stormwater maintenance. A little attention now can protect your home, your possessions, and your peace of mind when the rain hits hard again.
