Building Materials
Underground Drainage delivered to Swansea
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.
We deliver drainage to sites, driveways and yards across Swansea, from a single pallet for a small job to full loads for bigger builds.

Planning the drop in Swansea
Pipe travels in 3 m and 6 m lengths; fittings and chambers come boxed or loose with the load. Swansea is inside our standard mainland delivery area.
- On busy streets in Swansea, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
- Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
- If the drop point is block paving or soft ground, say so; heavy pallets and bulk bags can mark or sink.
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.
Choosing drainage
Covers for the location
Chamber covers are rated for loads, from pedestrian areas to drives. Tell us where each chamber sits.
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.
Underground Drainage in Swansea: questions
Is there a minimum order for delivery to Swansea?
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.
Can I connect to the public sewer?
New connections to a public sewer usually need approval from the local water company.
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.
Do you deliver drainage to trades and homeowners in Swansea?
Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.
