Owners of properties that have a septic system or treatment plant are required to maintain their system in good working order so that all wastewater is treated and contained onsite.
For best outcomes, make sure you know the location and layout of the septic system and disposal area on your property. A well maintained septic system will:
- Minimise health risks to your family and the broader community
- Protect ground and surface waters
- Prevent the degradation of land and vegetation systems
- Maintain healthy waterways
If you have an existing septic system and wish to make an alteration or extension to the system, please complete and submit the Septic Tank Installation Application Form ( PDF 93.76KB). Your plumber may make the application on your behalf.
For advice prior to carrying out any alterations or modifications to existing systems or the installation of a new system, contact Council’s Environmental Health Officer on 9262 6197 or refer to the EPA Septic Homeowner Guide ( PDF 498.41KB)
All work on Domestic Waste Water Systems should be carried out by a licensed plumber
Tips on Maintaining Your Wastewater System
To ensure that the wastewater system remains in good condition follow these simple steps:
- Ensure your tank is well sealed.
- Regularly maintain the disposal area by keeping grass short and reducing weeds.
- Prevent the entry of stormwater onto the disposal area and into your septic tank.
- Keep traffic off your drain field.
- Keep accurate records of de-sludging and maintenance.
- Minimise the amount of fats and oils washed into the system.
- Prevent materials such as nappies and sanitary napkins from entering the system.
- Check household products for suitability for use with a septic tank (look for cleaning chemicals that are septic safe).
- Minimise quantities of bleaches and disinfectants.
Never
- Never pour medicine or antibiotics down the drain. They kill essential bacteria in your septic system, increasing risk of contamination.
- Build or construct driveways, tennis courts, out buildings or otherwise seal over the drainage area.
Issues with Your Wastewater System
Warning signs that indicate there are trouble with your septic tank include:
• Toilets and drains that back up or drain slowly.
• High water level in the septic tank.
• Odours, surfacing sewage, wet spots or lush vegetation growth in the drain field area.
Do not ignore the problem. A poor performing septic system will impact on the environment and public health. It could also cost you significantly in the long term.
For operational problems with an existing system you should contact a licensed plumber.
Decommissioning Your Septic Tank
If your property is connecting to reticulated sewer or you are replacing an old system, the septic tanks must be decommissioned.
All works must be carried out by a licensed plumber in accordance with EPA guidelines.
The plumber will ensure the tanks are properly cleaned, disinfected and filled and pipes are permanently sealed.
You will be required to send a copy of the decommissioning certificate to Council.
