7 Bankstown, New South Wales Septic Tanks & Sewage Services

Septic tank prices in Bankstown vary depending on the size of the family home, just as installations will be pricier in less forgiving landscapes which require more planning and excavation. Wastewater management may also include the treatment of grey water - wastewater collected from washing machines, dishwashers and kitchen sinks.

How Do Septic Tank and Sewage Systems Work?

A large concrete or steel septic tank can hold up to 1,000 gallons of water. Wastewater comes down into the tank on one side from your Bankstown, New South Wales home’s sewage pipes and leaves the tank on the other side. Gases go up through a vent pipe through the roof of the house. Wastewater flows out of the septic tank and into a drain field made of perforated pipes, deeply buried and covered in gravel-filled trenches.

The drain field tends to be about 180 centimetres deep and sixty centimetres wide. Ultimately, the size of the drain field depends on how well the soil absorbs water, with slow-absorbing soil requiring a larger drain field. About one metre of gravel covers the drain pipes, with dirt filling the remainder.

Installing a septic tank system is best left to a licensed advanced wastewater treatment system installer, who can anticipate what size drain field your Bankstown, New South Wales system will need. Whether you’re working on a new build or a renovation, make sure your septic expert and installer openly communicates with your builder or plumber.
