Main Elements of Drainage in Commercial Premises

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

Connecting the Drainage Network

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

Keeping Access Simple

Access pipes are vertical sections that permit direct entry into the system. Installed at specific points, they help to remove obstructions and carry out routine checks. They can also double up as emergency points, reducing the chance of wastewater causing issues indoors.

Keeping Water Under Control

Anti-flood gullies stop surface water overwhelming drains. Useful in areas with frequent heavy rain, they maintain water flowing in the right direction, minimising the risk of damage. For businesses, this helps limit downtime.

Maintaining Proper Flow

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