Frequently Asked Questions

How often does my septic tank need to be pumped out?

For a family of 4, approximately every 3–5 years. This is to remove the build up of sludge in your tank—allowing your waste fluid to flow through the trenches, minimising blockages. A plumber regularly checks treatment plants such as Aqua-novas and he will let you know when it will need to be pumped out.

What else could cause a blockage in my septic tank?

Septic tanks use an enzyme to break down the waste so that it can pass through the filtration trench—chemicals and medicines can kill this enzyme causing the tank to smell and not break down the waste. Other things such as baby diapers and sanitary pads can cause blockages if frequently disposed into the system. Tree roots are another concern when they are planted too close to the trenches. The roots break through the trenches in search of water and will grow inside the pipe causing it to block over time requiring major repair.
