Frequently Asked Questions
Understanding the difference is critical, as they are two entirely separate systems handling completely different types of water. Your sanitary sewer system connects to your toilets, showers, kitchen sinks, and laundry. It carries contaminated blackwater and greywater safely away from your property to the Water Corporation's municipal treatment plants.
Your stormwater system, however, is designed solely to manage clean, natural rainwater. It collects water from your roof gutters and hardstand areas, directing it into underground soakwells on your property or out to the municipal street drainage. It is strictly illegal in Western Australia to connect stormwater pipes to the sewer line, as heavy rain will overwhelm the treatment facilities and cause raw sewage to overflow into the streets.
Because these pipes are buried deep underground, a collapse or severe break often goes unnoticed until the secondary damage becomes obvious. For sewer lines, the most common indicators are persistent foul odours lingering around your garden, multiple internal drains backing up simultaneously, or recurring severe blockages that return shortly after being cleared.
For stormwater drains, a broken pipe usually reveals itself during heavy winter downpours. You might notice sudden sinkholes or major depressions forming in your lawn or paving where the escaping water is washing away the underground sand. Unexplained damp patches against your exterior brickwork or water pooling aggressively around your foundation are also major red flags that require immediate investigation.
Yes, invasive tree roots are the number one enemy of underground plumbing in Western Australia. Large native trees and thirsty shrubs are constantly seeking moisture and nutrients in the soil. Condensation on the outside of your pipes, or a tiny pinhole leak at a PVC joint, acts as a magnet for these roots.
Once hair-like roots breach the pipe casing, they grow rapidly inside the nutrient-rich environment, forming a dense, solid mass that completely blocks the flow of water. As the root mass expands, it exerts immense pressure on the pipe walls, eventually crushing or snapping old terracotta and even modern PVC pipes completely. We use high-pressure jetting to clear the roots and then replace the compromised pipe section to prevent them from returning.
Absolutely. In the past, finding and repairing a broken underground pipe meant bringing in heavy machinery and blindly trenching through expensive exposed aggregate driveways, paving, or manicured lawns. This destructive method was incredibly stressful for property owners and massively inflated the cost of the repair.
Today, we use advanced CCTV drain cameras equipped with electronic sondes to travel inside the pipe and visually locate the exact point of the collapse. We then track the camera's signal from above ground to mark the precise depth and location of the fault. This allows us to perform a highly targeted, minimal-impact excavation - digging a single, small hole to replace the broken section rather than destroying your entire driveway.
Yes, we regularly manage the installation, repair, and maintenance of heavy-duty stormwater infrastructure for commercial properties, strata complexes, and industrial sites. Commercial hardstands and car parks collect a massive volume of rainwater very quickly, requiring high-capacity soakwells and robust spoon drains to prevent sudden, destructive flooding.
We can repair collapsed soakwells, replace sunken or dangerous heavy-duty traffic grates, and ensure your commercial property's stormwater management plan is fully compliant with local council regulations. We also offer routine clearing of commercial spoon drains to remove compacted sand and debris before the winter storm season hits.
