Pipe travels in 3 m and 6 m lengths; fittings and chambers come boxed or loose with the load. Milford Haven is inside our standard mainland delivery area.
- Keep cement, plaster and boards dry: have a tarpaulin or a garage space ready before they arrive.
- Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
- For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
How much will you need?
A 10 m run of 110 mm drain needs 4 pipes in 3 m lengths (or 2 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
Foul or surface water?
Foul (sewage) and surface water often need to go to different places. Check where your drains connect before you order.
Covers for the location
Chamber covers are rated for loads, from pedestrian areas to drives. Tell us where each chamber sits.
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 Milford Haven: questions
Do you deliver drainage to trades and homeowners in Milford Haven?
Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.
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).
Do I need an inspection chamber?
Drains need access points at changes of direction and junctions in many cases. Your design will show where.
Is there a minimum order for delivery to Milford Haven?
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.
