Wastewater Systems, Septic Tanks & Wastewater System Fees

Public Health Advice

Everyone who visits or lives in the Barossa has a important role to play in keeping  both the SA Water and Barossa Council sewer systems working.

Sewer systems operate as an entire unit life cycle, so what goes into your sewer drains at home affects everyone.

Tips to keep your sewer healthy.

  • Facial tissues, sanitary napkins, tampons and disposable nappies or wipes should NOT be flushed down the toilet. Remember only flush the 3 Ps….Paper, Pee and Poo. (see video links attached)
  • Food scraps should go into a bin or compost, not down the sink.
  • Use products that are biodegradable or septic tank safe to keep the bacteria working and use such products in moderation.
  • Ensure vents have mosquito-proof mesh fitted.
  • Ensure inspection openings and the access cover on the septic tank are sealed.

Wastewater Systems, Septic Tanks and Wastewater System Fees

There are three main types of waste control or septic systems available in South Australia;  the conventional soakage system, an aerobic wastewater system or connection to a community wastewater management system. Choosing the correct and most suitable system for your property is dependant on many factors such as the soil types, available allotment space and the availability or not of a community wastewater management systems connection (CWMS),

All waste control system installations must comply with the 'On-site Wastewater Systems Code'.


Conventional On-site Waste Disposal Systems

A conventional septic tank system consists of two components, the septic tank and the soakage trench.  The tank is installed in the ground with an access shaft over the lid opening to allow access to the tank for the purposes of maintenance and pumping out.  Tanks are required to be pumped out at least every four years.  If the tank is not pumped out regularly then solids build up and begin to migrate to the soakage trench and the system will fail to operate efficiently.  Once the efficiency of the soakage trench is compromised the effluent may break through to surface level and create an insanitary condition and health hazard.


Aerobic Wastewater Treatment Systems

An aerobic wastewater treatment system is comprised of a primary treatment tank and a secondary treatment tank. The first of these tanks acts like a traditional septic tank where solids and liquids are separated. The secondary tank incorporates an aeration pump to promote further breakdown of the effluent.  It then progresses to a pump chamber where it is disinfected and pumped to a designated above ground irrigation area. These systems require quarterly maintenance servicing by an accredited agent or trained personnel to ensure the reclaimed effluent complies with the criteria stipulated by the Department of Health.


Community Wastewater Management Systems

These systems are designed to collect and treat wastewater from each property using a common network.  Household effluent passes through a septic tank on the property and into a connection point to the common network. The wastewater treatment may include systems utilising various technologies with the reuse of reclaimed water.  These systems are currently available in the townships of Lyndoch,Mount Pleasant, Nuriootpa, Penrice, Springton, Stockwell, Tanunda and Williamstown. Note that not all allotments in these townships are serviced by these systems.
