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 Northern Ireland building work follows the Building Regulations (Northern Ireland), with guidance in the Technical Booklets, and applications go to the council's building control team.

Delivering drainage in Lisburn

Pipe travels in 3 m and 6 m lengths; fittings and chambers come boxed or loose with the load. Deliveries to Northern Ireland include a sea crossing, so we quote each order individually.

• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.

Sizing your order

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.

Your questions answered

Do you deliver drainage to trades and homeowners in Lisburn?

Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.

Can I connect to the public sewer?

New connections to a public sewer usually need approval from the local water company.

Can you deliver drainage to a site with restricted access in Lisburn?

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 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).
