Description
The 200mm D400 channel drainage sump unit acts as a key access chamber and sediment trap within linear drainage systems, helping to prevent debris from entering downstream pipework and reducing the risk of blockages.
Installed within a channel run, the sump unit allows silt and debris to settle before water is discharged into the drainage system, improving long-term performance and reducing maintenance requirements across commercial and civil projects.
Manufactured from high-strength polymer concrete, the unit offers excellent durability and resistance to chemicals, corrosion and environmental wear. The smooth internal surface promotes efficient water flow while minimising the risk of clogging.
Designed for seamless integration with 200mm channel drainage systems, including 8LOX ranges, the sump unit connects to a 160mm outlet and forms an essential part of a complete drainage solution.
Supplied with a ductile iron grating rated to D400 load class, the unit is suitable for applications subject to vehicle traffic including car parks, commercial yards and infrastructure schemes.
Why Use a Sump Unit?
- Prevents debris entering drainage pipework
- Reduces risk of blockages and maintenance issues
- Provides access point for cleaning and inspection
- Improves long-term drainage performance
Installation Guidance
Sump units are typically installed at the end of a drainage run or at low points to collect silt and debris.
On longer channel runs, additional sump units may be installed at intervals (commonly every 10–20 metres) to allow for maintenance access and improve long-term system performance.
