Important Components in Commercial Drainage

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

Connecting the Drainage Network

Access junctions connect several pipes and create entry points for maintenance. Located at planned positions, they simplify fault finding and removing blockages. Without them, upkeep in large networks would be labour-intensive.

Providing Entry for Inspections

Access pipes are vertical installations that permit direct entry into the system. Installed at specific points, they allow professionals 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. Useful in areas with frequent heavy rain, they ensure water flowing in the right direction, reducing the risk of flooding. For businesses, this helps limit downtime.

Keeping Wastewater Moving Correctly

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