Access Junctions, Pipes, Anti-Flood Gullies and Back Traps Overview


Important Parts of Commercial Drainage Systems


Drainage systems in industrial facilities require a set of specific features to handle water and waste effectively. Components such as access junctions, access pipes, anti-flood gullies and back traps support reliability and long-term function.



Connecting Drainage Lines


Access junctions provide access for cleaning while linking multiple pipes. Installed at sensible points, they help to find blockages and remove them quickly. In extensive drainage layouts, they simplify the effort needed for system upkeep.



Keeping the System Open for Checks


Access pipes are upright pipes giving direct access into the network. Placed at set intervals, they allow blockages to be cleared without disruption. They also double as overflow points, reducing the risk of wastewater overflowing inside commercial buildings.



Protecting Premises from Water


Anti-flood gullies block surface water from overloading drains. Ideal in areas of frequent rainfall, they stop backflow and ensure water moving into the system. This reduces potential damage, prevents business downtime, and shields property and staff.



Stopping Backflow


Back traps provide a barrier that blocks wastewater moving in the wrong direction. Fitted at critical locations, they support hygiene, control odours, and prevent unsanitary conditions.
