Underground Drainage for sites in Norfolk
Underground drainage is the system of plastic pipes, bends, junctions and inspection chambers that carries foul and surface water away from a building, most often in 110 mm PVC-U pipe.
Builders, trades and self-builders in Norfolk can order drainage for delivery to Norwich, Thetford and the towns in between.

Working out quantities for your Norfolk job
A 30 m run of 110 mm drain needs 10 pipes in 3 m lengths (or 5 in 6 m lengths), plus a bend or junction at each change of direction and an inspection chamber where your design shows one. Add pea gravel for bedding and surround and we will price the lot together.
How delivery works in Norfolk
Pipe travels in 3 m and 6 m lengths; fittings and chambers come boxed or loose with the load. Our standard mainland delivery area covers Norfolk.
- Give us the full postcode for the drop point; deliveries around NR are priced to the exact address.
- Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
- If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
Underground Drainage: choosing well
Foul or surface water?
Foul (sewage) and surface water often need to go to different places. Check where your drains connect before you order.
Building over or near a sewer
Building near a public sewer may need permission from the water company. Check before you dig.
In England, building work is checked against the Approved Documents, for example Part A for structure and Part L for energy efficiency, through your council's building control team or a registered building control approver.
Questions about drainage delivery in Norfolk
Is there a minimum order for delivery to Norfolk?
There is no fixed minimum. For very small orders we will tell you honestly if the delivery cost outweighs the materials, so you can decide.
Do you supply gutters and downpipes?
Yes, in common profiles and colours, with brackets and fittings.
What fall should a drain have?
Domestic drains are commonly laid at a gradient around 1:40 to 1:80 depending on the pipe size and flow; follow your approved design or your national drainage guidance (Approved Document H in England and Wales, Technical Handbook section 3 in Scotland, Technical Booklet N in Northern Ireland).
