How much will you need?
A 30 m run of 110 mm drain needs 10 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 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.
Building over or near a sewer
Building near a public sewer may need permission from the water company. Check before you dig.
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.
