Septic tank systems on unsewered properties

There are certain requirements for installing and managing septic tank systems on residential properties.

What are wastewater treatment systems?

Where a residential property can’t connect to the reticulated - or mains - sewer, sewage (water from toilets, kitchens, showers etc) must be treated and contained within the property boundary. Onsite domestic wastewater systems - commonly known as septic systems - treat this waste in a tank and discharge wastewater into a designated effluent disposal area.
