Adjacent ground shall be sloped away from the foundations to prevent ponding, falling 50mm in the first meter outside the footprint to a spoon drain or slotted dia90 pvc drain in scoria or coarse screenings which is to discharge to a min 300 x 300 grated pit in which in turn is to be connected via min 90 diameter pvc to the legal point of discharge
I'm not talking landscaping at all. I'm merely trying to ascertain that if the engineering report says that all ground needs to be sloped away from the house and drain to a pit which in turn discharges to a LPOD, should I be forcing the point with the builder to instate the pits and drainage system.
I do not have a specific drainage plan that shows where all the stormwater pipes go.
You have an incomplete site with no landscaping works and also no stormwater drainage.
If you don't have the pit already designed then the builder will charge you a variation for the work.
