Waste Water Systems

Septic systems

If you are in an area where mains sewerage is not available you will be required to install a septic system to remove, contain and/or treat waste. A permit is required from Council's Environmental Health Services before a new septic tank system is installed or an existing one altered.

Septic maintenance

If your home has an existing septic system it is your responsibility to make sure it is maintained regularly and is in good working condition.

You can ensure the system is working correctly by:

  • Being aware of the location and performance specifications of your septic system
  • Pumping out your septic tank at least every three years
  • Ensure treatment plants and sand filter systems are serviced as per manufacturer requirements and service reports are sent to council.
  • Protecting the effluent disposal area from livestock and vehicles
  • Not allowing fats, high nutrient detergents and sanitary products to enter the system

Council's Environmental Health Services can be contacted for further information on 1300 653 356 or

Decommissioning septic systems

If you no longer need a septic tank, the septic tank must be removed from the ground or broken at the base of the tank and back filled.

Any works to remove a septic tank must be done by a licensed plumber.

After the works are finished, a copy of decommissioning certificate must be provided to council.


Greywater includes all household wastewater, except toilet waste. It can be a valuable water resource and an increasing number of householders are reusing greywater for a variety of purposes. However, care must be taken as this practice can carry health and environmental risks.

Reusing greywater

Greywater can be used untreated, or it can be treated to varying degrees to reduce nutrients and disease-causing pathogens. The appropriate use of greywater depends on both the source of water and the level of treatment. The potential health risks associated with greywater reuse when it has been sourced from a multi-dwelling or commercial premises are considered potentially greater than those associated with greywater reuse within a single domestic premises.

Greywater reuse must always occur in a safe and controlled manner. Reuse that places public health at risk may be investigated by council officers.
