Waste Water Management

Wastewater Applications

If you are building a new house, renovating an existing house, altering existing plumbing, or upgrading an existing Wastewater system then you will be required to submit an application to Council to install a wastewater system, or to alter existing plumbing. When lodging a Development Application for a new dwelling or alteration to a Dwelling which involves changes to the existing plumbing you should also lodge a WCS application at the same time. The Council will not issue Development Plan Consent until a Wastewater application has been approved.

A wastewater system includes:

  • a septic tank and soakage system
  • a connection to Council's common wastewater management system (CWMS)
  • an Aerobic Sand Filter treatment and disposal system
  • an Aerobic Waste Water treatment and disposal system

The construction, installation or alteration of a septic tank system (wastewater system) requires approval under the provisions of the South Australian Public Health (Wastewater) Regulations 2013.

Any persons wishing to install or alter a wastewater system, including the alteration of any plumbing or drainage or intending to construct an addition to a house or to any building work that may encroach on the existing system, is required by the South Australian Public Health (Wastewater) Regulations  2013 to make an application and receive approval from Council.

The Coorong District Council provides a full approval and inspection service of all installations and alterations when notified. This requires all plumbing contactors to advise Council of any work that they are undertaking in our area. Plumbing work can only be carried out by licensed plumbers.

Councils Environmental Health Officer has recently created two information booklets to assist in the lodgement of WCS applications. The booklets aim to assist in the lodgement of a WCS application as well as provide advice on the maintenance and care of Wastewater Systems.

No work in relation to the construction, installation or alteration of a wastewater system can occur until the approval of the relevant authority has been granted. The installation or alteration of a wastewater system is primarily a role of the local Council.

Here is the link to the application form:

To install a septic tank and soakage system you will first need to have a report undertaken by a qualified Wastewater engineer to determine the suitability of the soil for effluent disposal. The engineer will determine which is the most appropriate form of wastewater disposal based on the soil type.

Installing an Aerobic Waste Water Treatment System

The aerobic wastewater treatment system is a mechanically driven system that WILL require on-going maintenance conducted by a trained technician (owner/occupiers are not permitted to service their own system without training). These systems recycle and disinfect the effluent so that it can then be utilised on-site via an irrigation system. A report needs to be undertaken by a wastewater engineer to determine the suitability of the soil for the treated effluent and the size of the irrigation area required.

Installing an Aerobic Sand Filter System

The aerobic sand filter system is gravity fed and requires minimal maintenance, which can be carried out by the owner. This system also recycles and disinfects the effluent for distribution via an irrigation system. A report needs to be undertaken by a wastewater engineer to determine the suitability of the soil for the treated effluent and the size of the irrigation area required.

Renovating an Existing House

If you are renovating an existing house then you may also need to submit a wastewaterl systems application form to Council for approval if you are:

  • Increasing the number of rooms
  • Adding or upgrading any plumbing fixtures (eg: ensuite / kitchen / laundry / bathroom)

If you are increasing the number of rooms in the house contact the Council Environmental Health Officer as to whether your existing system is sufficient or if a larger system will be required.If you are adding or upgrading any plumbing fixtures you will still need to complete the wastewater application form.

Installing A Connection Point for CWMS

The Coorong District Council has Community Wastewater Management Systems (CWMS) operating in Tailem Bend, Meningie, Tintinara and Wellington East. To find out whether you are in a CWMS area contact the Environmental Health Officer on 1300 785 277.

Inspections

Council requires that any new system or an alteration to an existing system must be inspected at the following stages and prior to backfilling or covering:

  • underfloor plumbing and drainage
  • installation of septic tank
  • installation of the effluent disposal system

** Fines can apply for not notifying the Council at these stages **

 

The inspection of systems approved by Council must be carried out by the Environmental Health Officer.

For additional information about Waste Water Management or Inspections please contact Council's Development and Environmental Services team on 1300 785 277

The technical requirements for the Onsite Wastewater Systems are outlined in the On-Site Wastewater Systems Code
