Any Drainage poeple on here ?

[greenacc]

So all the rain we had recently almost washed my house away so i'm attempting to solve the problem with a few ag lines and a proper stormwater pipe from the pergola.
Got a 100mm ag line and 90mm PVC and trying to run them both in the same trench. Any tricks of the trade i might not have thought of would be welcome !!

No one would have an answer to that. Where you running it from or behind and where too.

OK, the block is sloping from back yard to front. Running a trench across the back lawn and around the side of the house. Back yard is about a metre higher than the house and not drained well at all ..

When i built i had this problem. Ended up running slotted pipe across the back and down each side of the house, hooking into the storm off the sides of the house, worked a treat.

sounds exactly like what i'm doing. Assume you laid the slotted pipe in a trench, how deep ?..

From memory only deep enough to put some 10 mm agg on top plus some top soil, mabye 8-10 inches or so.
