Re: Aus Standard for depth of drainage pipe ? 12Apr 18, 2014 9:21 am bashworth I would tend to lay the ag pipe about 300mm min myself. The best thing to fill the trench with would be a 10mm single size aggregate. I wouldn't bother with geofabric after a few years it gets clogged,and the gravel will filter out any dirt. 100mm dia should be big enough for what you need. why would you not have a layer of 10mm in the bottom of the trench, then put sand, then your pipe with geofabric, then sand again above and a few cm over the geofab pipe then back to 10mm and then something larger then back to normal soil (or if your soil is more clay based, maybe mix the soil above with a certain percentage of sand?
