Quantities: a worked example
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.
Planning the drop in Powys
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 Powys.
- Pallets left on a pavement can block the footway, so plan a drop point inside your boundary where you can.
- Weight limits on bridges or private roads near the site matter for larger lorries, so mention any you know of.
- Give us the full postcode for the drop point; deliveries around SY are priced to the exact address.
Choosing drainage
Building over or near a sewer
Building near a public sewer may need permission from the water company. Check before you dig.
Covers for the location
Chamber covers are rated for loads, from pedestrian areas to drives. Tell us where each chamber sits.
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.
