Site Specifics
A 3m x 3m hole is dug for your tank to be buried. In addition a 6m long x 1.5m wide trench is dug for your ASF (Aerobic Sand Filter). The finish product is the top of a concrete tank lid and a small, long and skinny trench that is finished with sand OR can be turfed over by the client.
Your Land Application Area (Irrigation) is designed by a licensed geotechnical engineer and could be either Surface / sprinkler spray, subsurface drip or subsurface absorption beds. This depends on council requirements, set back distances from site overlays like water courses or green zones & site boundaries etc.
