Folks
Tried this in plumbing but not sure if this forum is better suited.
I'm looking to have a new drainage run installed to collect rainwater from one r/w pipe at the front of the house and collect the flow from a washing machine in the cellar (about half way along the gable end and pumped via a Sani) and connect to the existing combined drain at the back of the house.
The total run is about 12m being one 1m length, 90 deg turn, 9m length, 90 deg turn, and one 2m length connecting into the drain at the back of the house.
Basing the trench depth as 550mm and allowing for siting the pipe on 100mm pea shingle can anyone give me an idea of budget figures?
Trench wall supports would be needed as the run would have to be close to my garden wall.
Any help much appreciated.
