Getting the right 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 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.

Delivery to Hanworth: what helps

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

• 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.
• For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.

Underground Drainage questions

Is there a minimum order for delivery to Hanworth?

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.

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).

Can I add other materials to my Hanworth 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 building control will confirm.
