Septic tanks


Septic tanks are a cost effective septic solution for residential waste water treatment. With low maintenance requirements and often no need for pumps, they’re ideal for remote and rural households. However, the quality of the final liquid waste is poor. Generally you will only be allowed to install one of these if your land is greater than 2.5 acres and is without dams or nearby waterways. 

Have a smaller property? Our wastewater treatment systems and tanks with sand filters are a better fit for smaller spaces or for land with environmentally sensitive features.

How do septic tanks work?

The work we do above ground makes septic tank installation and repairs look easy, but the real magic happens below ground.

A septic tank is typically a concrete or plastic tank buried below ground. It safely collects and stores waste water from your bathroom, toilet, kitchen and laundry through pipes that run to the tank. The waste settles at the bottom as sludge, and the fats and oils rise to the top as ‘scum’. The wastewater is digested by good bacteria. This turns the waste into effluent. This flows into absorption trenches and returned to the earth – away from your house, away from your drinking water and away from you.
