Understanding Key Drainage Components

Main Elements of Drainage in Commercial Premises

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

Keeping Water Under Control

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

Preventing Backflow

Back traps function as barriers to prevent wastewater reversing back into the network. Placed in critical positions, they support hygiene, limit odours, and avoid contamination inside commercial areas.
