Hi all, I am having to put in a soakaway to take rain from a new extension roof. All specs worked out so no issues there. My question is this; is there a minimum depth that the pipes have to be buried? I ask this because the gullies I assume will be flush with the final surface (or just below and create a gully around it?) If the gullies are to be flush with the surface, then by the time I have 100mm of pea shingle for th epipes to lay on, then the pipe, I won't have much for my concrete (a footpath, only light foot traffic, no vehicular access) . The pipe has to go across a lawn too for about 3m to the new soakaway. I need to protect the pipe in the lawn from damage from forks etc and was going to lay slabs over the pipe with pea gravel below, then reinstate the lawn over the slabs? Thanks
Doc H is rather vague with regard to min depth, generally the actual depth is largely determined by the need to maintain the correct gradient from all interconnects, whilst maintaining adaquate protection above - either by secondary means or a higher grade pipe http://www.planningportal.gov.uk/uploads/br/BR_PDF_ADH_2002.pdf
Cheers Sean-ork ........ I'm also enquiring with BCO if I can bring the soakaway closer to the house as 5m away will be right on the boundary and too close to a nearby garage ... I await the answer from the manager!
