How much will you need?

A 26 m run of 110 mm drain needs 9 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.

Getting drainage onto your County Down site

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.

• On busy streets in County Down, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
• Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
• Tell us the best drop point, such as a driveway, front garden or the kerb, and whether a lorry can park close to it.

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 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.

Underground Drainage in County Down: questions

What do I bed drainage pipe in?

Usually pea gravel or a similar granular material around the pipe. We can add it to the order as bulk bags.

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.

How soon can drainage be delivered in County Down?

We confirm the delivery date when we price your order, before you commit. It depends on the product, the quantity and whether it is a stock line or made to order.

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

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.
