Preparing for renovations? Fixing drainage problems? No matter why you’re looking for that stormwater pipe or drain on your property, it can be an absolutely crucial – and extremely difficult – task. As experienced plumbers, you’d be amazed how often we’re asked, “How do I find stormwater pipes on my property?” But the precise answer really does depend on a combination of physical investigation, research, and sometimes professional help.
As you no doubt know, stormwater systems are vital for directing rainwater away from your home and garden – but they can often be completely forgotten about until a problem arises. Not sure where to start? This simple guide will walk you through the process step-by-step – starting with the easiest methods and moving through to much more involved solutions if required.
Why do you need to find stormwater pipes?
Knowing where stormwater pipes and drains are on your property can save you time, money, as well as big, expensive, messy headaches. Why are you looking for yours?:
- To avoid damaging them before carrying out renovation or landscaping projects?
- Solving flooding or drainage problems?
- Carrying out maintenance and repairs?
Step-by-step: How to locate stormwater pipes
Don’t feel silly or overwhelmed if you can’t find the stormwater pipes you’re looking for. Let’s start with the easiest methods and progress through to advanced techniques if they’re required:
1. Look for visible clues
Start by walking around your property and looking for signs of the stormwater system.
Gutters & downpipes: Follow where your roof gutters direct rainwater, as the downpipes often connect to an underground stormwater drain on your property.
Grated drains: Check for grated or open drains in your yard, driveway, or garden. These are often part of the stormwater system.
Water flow: Observe how rainwater flows on your property during heavy rain – it can often lead you to the entry points of your stormwater system.
2. Check your property plans
If visible signs don’t provide enough information, the next step is to consult your property plans.
Stormwater plans for my house: Building plans and related documents often include diagrams showing the layout of your system, making it easy to figure out how to find storm water drains on your property. These plans may be with your property purchase documents or available from your local council.
Contact the local souncil: Wondering how to find stormwater plans? In Queensland and beyond, councils typically maintain records of drainage systems. If you don’t have your stormwater plans for my house, request them from the council or try:
- Building approvals/renovation records
- Private plan retrieval services
- State or utility authorities.
3. Use a metal detector or ground penetrating tool
While this might not sound too simple, once you have these technologies in your hand, they’re not too difficult to use.
Metal detector: Stormwater pipes often have metal grates, lids, or fittings. A metal detector can help pinpoint their location.
Ground Penetrating Radar (GPR): This advanced tool can detect underground pipes and utilities without digging. While GPR equipment is typically used by professionals, some rental options are available for homeowners.
4. Look for access points
Stormwater systems often include inspection or access points, like:
Stormwater pits: These pits are designed for maintenance and are often located in gardens or driveways.
- Remove the lid carefully to check for connections to underground pipes.
Cleanout pipes: Look for capped pipes sticking out of the ground, which allow access to stormwater systems for cleaning and repairs.
5. Use dye testing
Those pipes still proving elusive? You could try a dye test:
- Add a non-toxic, brightly coloured dye to a downpipe or grated drain
- These are available at plumbing or hardware stores
- Observe where the dye flows – it can help trace the path of underground pipes.
Dye testing works best when water is already flowing through the system, such as after rain or by adding water manually.
6. Trace pipes with a drain camera
A CCTV drain inspection camera is a powerful tool for locating stormwater systems:
- Insert the camera into a drain opening or access point
- Follow the camera’s footage to identify the layout and condition of the pipes.
Drain cameras are often used by professional plumbers but can sometimes be rented by homeowners.
7. Consult a plumber
How did you go? Find those stormwater pipes and drains? If not, it’s time to call in the experts. Experienced, fully-licensed plumbers have all the specialised tools and expertise they need to locate even the most hidden stormwater features.
Professional plumbers can:
- Use CCTV cameras or advanced detection tools.
- Pinpoint the exact location and depth of your pipes.
- Provide advice or carry out repairs for damaged or blocked stormwater drains and systems.
What if you simply can’t find the pipes?
Sometimes, locating stormwater pipes is even more challenging than you ever imagined, due to old, poorly installed, or undocumented systems. In these cases:
- Plumbers may recommend excavation or hydro jetting to identify and clear blockages.
- It’s important to avoid digging without knowing the exact location of pipes, as this can cause damage to your plumbing and surrounding infrastructure.
Tips for maintaining stormwater systems
Once you’ve located your stormwater pipes, follow these tips to keep them in good condition:
Regular inspections: Check your system for visible damage or blockages.
Clear debris: Remove leaves, dirt, and other debris from gutters and grated drains.
Address blockages quickly: Call a blocked drain plumber if you notice slow drainage or flooding.
Professional cleaning: Schedule regular maintenance, such as hydro jetting, to keep pipes clear.
