I'm currently digging out for a new patio, I have accounted for a 1:80 fall away from the house, at the end of the patio I will need to build a retaining wall, probably 2-3 blocks high, with steps. Do you think I would need an ACO at the end of the patio, or could I just have a channel of loose stone against the wall, or nothing needed at all?
Aco drain required or not

If you had an ACO, what would it drain into? Be meticulous to achive a 1:80 fall without any pooling.
The 1:80 on porcelain should be fine, no? Can't see how that can go wrong if its set by a string line.
The aco would drain to a main sewer. But if its not necessary i would rather not do it
