Important Components in Commercial Drainage

Commercial drainage systems are made up of various components, each with a specific function. Access junctions, access pipes, anti-flood gullies and back traps all support in keeping the system functional and robust over time.

Linking Pipework Together

Access junctions join several pipes and create entry points for maintenance. Located at planned positions, they streamline fault finding and clearing blockages. Without them, upkeep in large networks would be time-consuming.

Making Maintenance Straightforward

Access pipes are vertical installations that enable direct entry into the system. Installed at set points, they make it easier to deal with obstructions and carry out routine checks. They can also serve as safety valves, reducing the chance of wastewater causing issues indoors.

Flood Protection

Anti-flood gullies block surface water overwhelming drains. Practical in areas with frequent heavy rain, they maintain water flowing in the right direction, minimising the risk of overflow. For businesses, this helps keep operations safe.

Preventing Backflow

Back traps function as barriers to stop wastewater reversing back into the network. Placed in key positions, they support hygiene, control odours, and stop contamination inside commercial areas.
