How much will you need?
A 26 m run of 110 mm drain needs 9 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.

- If neighbours share the access, it helps to let them know a lorry is coming.
- If the site is up a shared drive or behind other houses, tell us the distance from the road.
- Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
Underground Drainage: choosing well
Building over or near a sewer
Building near a public sewer may need permission from the water company. Check before you dig.
Foul or surface water?
Foul (sewage) and surface water often need to go to different places. Check where your drains connect before you order.
Wales has its own Approved Documents, including its own Part L for energy efficiency, and building control is handled by the local authority or a registered approver.
Common questions from Gwent
What do I bed drainage pipe in?
Usually pea gravel or a similar granular material around the pipe. We can add it to the order as bulk bags.
What size drainage pipe do I need?
110 mm is the standard size for most domestic underground foul and surface water drains; 160 mm is used for larger runs. Your design or building control will confirm.
Is there a minimum order for delivery to Gwent?
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.
How soon can drainage be delivered in Gwent?
We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.
