Description
The 100mm D400 channel drainage sump unit provides a dedicated collection and maintenance point within a linear channel drainage system, allowing surface water to discharge from the channel run into downstream drainage pipework.
Designed for integration with the Polycon 8LOX 100mm D400 channel drainage system, the sump is manufactured from durable polymer concrete and supplied with a D400 ductile iron grating.
With a 500mm length, 140mm overall width and 600mm overall depth, the sump incorporates a 110mm outlet connection for connection into the downstream drainage system.
