Why Stormwater Flooding Happens
Stormwater systems are designed to carry rainwater away from your property through gutters, downpipes, pits and underground drainage pipes. When the system cannot move water away fast enough, stormwater begins to back up.
This can cause pits to overflow, water to pool in yards, and in some cases flood areas around the home.
Across many homes in Campbelltown and the Macarthur region, flooding is often caused by blocked pipes, damaged drainage lines, or older stormwater systems that were not designed to handle heavy rainfall.
Early Warning Signs
Some signs that your stormwater system may be struggling include:
• Water pooling quickly in the yard during rain
• Stormwater pits filling rapidly during storms
• Overflow from downpipes
• Gutters spilling water even when recently cleaned
• Soft or soggy patches of lawn after rainfall
These warning signs usually indicate that the drainage system is partially blocked or not draining efficiently.
Common Causes
Several issues can cause stormwater flooding around a home:
• Tree roots entering stormwater drains
• Blocked gutters or downpipes
• Collapsed or damaged stormwater pipes
• Undersized drainage pits or pipes
• Heavy rainfall overwhelming older drainage systems
Over time, debris, roots and sediment can restrict water flow through the drainage network.
DIY Checks
Before winter arrives, homeowners can perform some simple checks to help reduce the risk of flooding.
• Clean gutters and downpipes thoroughly
• Remove leaves and debris from stormwater pits
• Run a garden hose into downpipes to test water flow
• Check for soft soil or pooling water areas in the yard
• Ensure landscaping slopes direct water away from the house
These checks can help identify early drainage issues before major storms arrive.
What Homeowners Can Do
There are also several preventative steps homeowners can take to protect their property.
• Trim trees near drainage lines
• Install gutter guards to reduce leaf buildup
• Move garden soil away from house foundations
• Keep stormwater pits clear throughout the year
Regular maintenance helps keep stormwater systems operating effectively during heavy rainfall.
When to Call a Plumber
If flooding continues despite cleaning and maintenance, the issue may be deeper in the drainage system.
You should contact a plumber if:
• Severe flooding occurs during storms
• Stormwater pits overflow even when clean
• Water pools against the walls of the house
• Repeated stormwater backups occur
• There are signs of collapsed or damaged drainage pipes
A professional inspection can identify blockages, pipe damage or drainage design issues.

Long-Term Drainage Upgrades
Older properties sometimes require drainage upgrades to properly handle heavy rainfall.
Common improvements include:
• Replacing old clay stormwater pipes with modern PVC pipework
• Installing additional stormwater pits in low areas
• Adding spoon drains or channel drains around problem areas
• Routine jet cleaning of drainage lines before winter
Upgrading the drainage system can significantly improve how your property handles large storms.
FAQs
Why does my yard flood even in light rain?
This usually indicates that your stormwater system is partially blocked or unable to handle the volume of water entering it.
Do I need larger or additional stormwater pits?
Properties that collect large amounts of surface water may benefit from additional pits or improved drainage design.
Winter storms can quickly expose weaknesses in stormwater systems. Preparing your drainage before winter is one of the best ways to protect your home from flooding, water damage and drainage failures.
