How much of my land will need to be allocated for the disposal and tank area?

The tank is 2.5 diam x 2.5m deep. The exposed above ground portion is the environmentally green coloured lids (see Hynds Web pics) The land application (irrigation) area will be based on the type of pipework that is to be installed. The pipework will be chosen based on your soil type and location of the area for placement eg 3 bedroom 100m2 Trench disposal (flat land) – 300m2 drip irrigation (any contour)

Do I have to do anything to look after my treatment system?

Always consider what you put down your waste pipes to keep your tank bacteria healthy. Check your homeowners manual for do’s and dont’s. You should have a valid service contract with an approved service technician. In the first few months you should do a simple check of your irrigation filter monthly.

Can I have a waste disposal?

Waste Disposal systems put additional undigested matter into a wastewater system making it work harder. Not recommended. Composting may be a better alternative

Can I have a conventional septic tank instead of an advanced treatment systems?

Your council will advise if your region is suitable for a septic tank. A septic tank functions by the waste being treated within the land on a flat contour, therefore the soil/land conditions have to be proven very suitable. An Advanced treatment system treats the effluent within the treatment tank. The resulting treated clear liquid is more readily accepted by the environment and can be transported through small irrigation pipe on any contour
