Understanding Key Drainage Components

Important Components in Commercial Drainage


Commercial drainage systems are made up of multiple components, each with a clear read more function. Access junctions, access pipes, anti-flood gullies and back traps all help in keeping the system efficient and durable over time.



Linking Pipework Together


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



Providing Entry for Inspections


Access pipes are vertical pipes that allow 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 double up as overflow outlets, reducing the chance of wastewater causing issues indoors.



Flood Protection


Anti-flood gullies prevent surface water overwhelming drains. Practical in areas with frequent heavy rain, they maintain water flowing in the right direction, minimising the risk of damage. For businesses, this helps protect property.



Keeping Wastewater Moving Correctly


Back traps act as barriers to stop wastewater reversing back into the network. Placed in key positions, they help hygiene, reduce odours, and prevent contamination inside commercial areas.
