Catchpits for the catchment of silt and solids in stormwater systems with sewer pipework (en1401).
Our catchpit chambers are designed for the catchment of silt and solids in stormwater systems with 160mm en1401 pipework. They prevent silt and debris from building up and causing blockages.
They are classed as non entry access and are limited to 3 metre inverts in adoptable applications as stipulated in Sewers for Adoption 2013 (Section B2.2 Access).
Inspection Chamber Questions?
So you know you need to install an inspection chamber but you have a few questions, such as what’s its actual purpose and what’s the difference between adoptable and non-adoptable inspection chambers.
We’ve put together a beginners guide to inspection chambers that should answer any questions you may have.
Compatible with sewer pipe (en1401)
Our catchment chambers are specifically designed for en1401 upvc sewer systems pipework.
Our catchpits chambers are manufactured using high strength polyethylene, making them strong and robust, and can be installed in minimum granular surround.
The catchpits are all water tested and supplied with seals as a fully watertight chamber.
We supply two chambers, both designed for the catchment of silt and solids in stormwater systems with 160mm en1401 pipework:
1.5 metre: Our 1.5 metre inspection chamber/catchpit comes with 160mm en1401 connections, which has a 500mm deep sump under the pipework which will trap and retain silt and solids.
2 metre: Our 2 metre inspection chamber/catchpit comes with 160mm en1401 connections, which also has a 500mm deep sump under the pipework to trap and retain silt and solids.
Extension risers – These can be used to increase the invert above 1 metre. If above 1.2 metres then the access cover needs to be restricted to 350mm for safety, again stipulated in Sewers for Adoption.
Reducer Caps – We can also supply a sealed cap to fit over the riser which has a 350mm circular opening that will accommodate most access covers of this size
Access Covers – We supply a range of access covers from Pedestrian Duty to D400 Heavy Duty.
