01
The right treatment level for the site
Traditional septic tanks and soakage trenches provide primary treatment and depend on suitable soil, groundwater, available land, water use, and council requirements.
Where a site requires a higher treatment standard, a secondary or advanced system can treat wastewater before it moves to the approved land application area.
02
Septic tanks
A septic tank provides primary treatment. Solids settle in the tank and the remaining liquid moves to a soakage trench or bed, where the surrounding soil completes the treatment. It suits properties with suitable soil, enough available land, and a council that accepts primary treatment at that location.
Where the soil drains poorly, groundwater sits high, the available land is limited, or the consent requires a higher standard, a secondary or advanced system treats the wastewater further before it reaches the land application area. We assess the site first, then recommend the treatment level that the property and the consent actually require.
