Picking the right product
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.
A quick quantity check
A 22 m run of 110 mm drain needs 8 pipes in 3 m lengths (or 4 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.
