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.

Getting drainage onto your Oadby site

Pipe travels in 3 m and 6 m lengths; fittings and chambers come boxed or loose with the load. Oadby is inside our standard mainland delivery area.

• Give us the full postcode for the drop point; deliveries around LE2 are priced to the exact address.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.

Estimating your drainage

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.

Underground Drainage questions

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 Oadby?

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 you deliver drainage to a site with restricted access in Oadby?

Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.

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.
