Sizing your order

A 15 m run of 110 mm drain needs 5 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.

Getting drainage onto your West Glamorgan site

Pipe travels in 3 m and 6 m lengths; fittings and chambers come boxed or loose with the load. Our standard mainland delivery area covers West Glamorgan.

• Mention any overhead cables, low branches or narrow gateways, because they decide whether a crane offload is possible.
• Give us the full postcode for the drop point; deliveries around SA are priced to the exact address.
• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.

Before you order drainage

Building over or near a sewer

Building near a public sewer may need permission from the water company. Check before you dig.

Foul or surface water?

Foul (sewage) and surface water often need to go to different places. Check where your drains connect before you order.

Wales has its own Approved Documents, including its own Part L for energy efficiency, and building control is handled by the local authority or a registered approver.
