20 Years Solving Stormwater Drainage Problems Across Kalinga

An overflowing pit is usually a sign that water is arriving faster than the system can carry it away. This can happen because leaves, silt or debris have built up inside the pit or the connecting pipe, because the pipe itself has partially collapsed or been invaded by tree roots, or because the line was undersized or poorly graded when it was originally installed. A camera inspection is the most reliable way to identify which of these is causing the surcharge.

Yes, and it's a common issue in established suburbs with mature trees and gardens. Roots are drawn to the moisture inside stormwater pipes and can enter through small cracks, loose joints or old earthenware fittings, gradually growing thicker and restricting flow. Left alone, root intrusion can eventually cause a full blockage or contribute to a section of pipe collapsing altogether.

The legal point of discharge is the specific location, such as a kerb, council drain or interallotment drainage system, where your property is approved to release stormwater runoff. Directing water anywhere else, including onto a neighbouring property or into the sewer, can cause disputes, damage and council compliance issues. A plumber can confirm your property's legal point of discharge and correct the connection if it isn't set up properly.

Stormwater and sewer systems are designed to remain completely separate, so a cross connection between the two is a genuine problem rather than a minor inconvenience. It can lead to sewage overflows during heavy rain, unpleasant odours, and issues with council compliance. If you suspect your lines might be crossed, particularly in an older home, it's worth having a plumber inspect the connections with a camera to confirm.

A straightforward blockage from leaves or silt can often be cleared with jetting, and flow returns to normal afterwards. If the pooling or flooding keeps returning despite regular cleaning, or you notice the ground sinking near a pipe, cracked pits, or gurgling sounds after rain, these point to a structural problem such as a collapsed section, root damage or poor original installation. A CCTV inspection will show clearly whether cleaning is enough or a repair is genuinely needed.
