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.

In Scotland most building work needs a building warrant from the local authority, assessed against the Building Standards Technical Handbooks.

Getting drainage onto your Oban site

Pipe travels in 3 m and 6 m lengths; fittings and chambers come boxed or loose with the load. Oban is in an area where deliveries are priced individually because of the distance and access, so we quote each order separately.

• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.

Sizing your order

An 18 m run of 110 mm drain needs 6 pipes in 3 m lengths (or 3 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.

Underground Drainage questions

Can I add other materials to my Oban delivery?

Yes. Put everything on one list, from drainage to fixings and PPE, and we will price it as one delivery where the products can travel together.

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 the council's building standards service will confirm.

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).

Is there a minimum order for delivery to Oban?

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.
