Do I need a secondary treatment system?
It depends on your section size, soil type and how close you are to waterways. Many councils now require secondary treatment for new rural homes. We’ll assess your site and tell you what’s needed.
How often should a septic tank be pumped out?
Most household septic tanks need pumping every 3 to 5 years, depending on tank size and how many people live in the home. Secondary treatment systems also need regular servicing to keep them working well.
