Underground Drainage for sites in Devon
Underground drainage is the system of plastic pipes, bends, junctions and inspection chambers that carries foul and surface water away from a building, most often in 110 mm PVC-U pipe.
Across Devon, from Plymouth to Tiverton, we supply drainage delivered to site with the price and date confirmed in writing.

A quick quantity check
An 8 m run of 110 mm drain needs 3 pipes in 3 m lengths (or 2 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.
How delivery works in Devon
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 Devon.
- For a phased build we can split the order so materials arrive as each stage starts, which keeps the site clear.
- On busy streets in Devon, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.
- If the site is up a shared drive or behind other houses, tell us the distance from the road.
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.
Underground Drainage questions
Can I connect to the public sewer?
New connections to a public sewer usually need approval from the local water company.
Can I add other materials to my Devon delivery?
Yes. Put everything on one list, from drainage to fixings and PPE, and we will price it as one delivery where the products can travel together.
Do you deliver drainage to trades and homeowners in Devon?
Both. Trades can apply for a trade account; homeowners and self-builders can order on a delivered quote.
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.
