Septic Tank Installation Coffs Harbour

We can install septic tanks for a range of residential, commercial and industrial properties, and we can help with council permits and the correct positioning too. A septic tank is an underground chamber where solid and organic waste flows for basic treatment.


Our team of qualified technicians can advise you on the best type of septic tank for your property, and handle all elements of installation for a sustainable water treatment solution. We can help with septic tank inspections, making sure your tank is fully operational or installing a specialist Aerated Wastewater Treatment system so you can use your wastewater for irrigation.

Frequently Asked Questions

  • What size septic tank do I need?

    In accordance with AS/NZS 1546.1:2008 standard, a property with 4-6 bedrooms will need a 4,500l tank. For smaller properties, a 3000l tank should suffice. Obviously individual circumstances have a big influence on determining an appropriate tank size - if you're unsure, ask the team at VR Marsden Plumbing Services & Mullaway Maintenance for suitable recommendations.

  • How often should I empty my septic tank?

    This depends on the number of people using the facilities on your property and the size of the tank. In general, if an appropriately sized tank has been fitted initially, tanks will need to be emptied every three to five years. If you spot any signs that indicate the tank may need emptying (see above) then give us a call to come and check it for you.

  • How does a septic tank work?

    The tank contains naturally occurring bacteria that break down waste when it enters the tank. Solids settle at the bottom of the tank, gradually filling it. Liquid waste is cleaned by bacteria and then flows away into a patch of ground close to the tank, known as the soakaway. Read more in our blog about how septic tanks work!
