Collection of wastewater for large developments and towns

Communities or developers may choose to install collection, treatment and recycled water systems that service the following as an alternative to each property owner treating and disposing of wastewater on-site (within property boundaries):

  • whole towns
  • a cluster of premises
  • tourist developments
  • new subdivisions
  • developments on Aboriginal lands

Community Wastewater Management Systems

Community Wastewater Management Systems (CWMS) collect, treatand recycle wastewater from each property using a common network. They can include:

  • gravity sewerage systems
  • pressure sewerage systems
  • vacuum sewerage systems
  • septic tank effluent drainage schemes (STEDS)

Treatment methods

The extent of treatment provided by the system must be suitable for the safe use or reuse of the recycled water. Treatment methods may include (but are not limited to):

  • activated sludge
  • extended aeration
  • intermittently aerated/decanted systems

Approval for the use of CWMS

Approval must be obtained before a CWMS is installed. This includes extensions to existing schemes.

Application are made by completing the Application for wastewater systems and recycled water schemes for towns, subdivisions and communities (PDF 45KB) form and submitting to SA Health’s Wastewater Management Section.

We recommend that you discuss the proposed installation with Department officers in the early stages of planning a development. There may be important design considerations that need to be identified before planning decisions are made.

Refer to the Community Wastewater Management Systems Code (PDF 111KB) for information on design and legal requirements.

Recycled Water Guidelines

The South Australian Recycled Water Guidelines (PDF 1.3MB) provide advice on how to obtain licences and approvals for recycled water schemes in South Australia. The Guidelines replace the rescinded South Australian Reclaimed Water Guidelines 1999.

The Guidelines use the Australian Guidelines for Water Recycling, as the scientific reference for the supply, use and regulation of recycled water. The Guidelines also contain recycled water process information which was previously available in the Reclaimed Water Guidelines.

Recycle water schemes

The use of recycled water schemes in towns and large developments requires approval before a recycled water scheme is installed. Applications are made by completing the Application for wastewater systems and recycled water schemes for towns, subdivisions and communities (PDF 45KB) form and submitting to SA Health’s Wastewater Management Section.

Application fees apply. Contact SA Health’s Wastewater Management Section for the current fee.

A Recycled Water Schemes: information for applicants (PDF 199KB) guide has been produced to advise you of the:

  • application process and requirements, in particular for high quality recycled water schemes
  • recycled water legislation and guidelines

Compliance requirements

All applicants must make sure they comply with the approval requirements of other government agencies. Compliance with other agency requirements is separate from the SA Health’s approval process and include:

Annual reports

Suppliers of recycled water must undertake water quality testing and submit their results to DHA each year. The requirement for annual reporting is summarised in the Explanatory Note - Annual Reporting Requirements for Recycled Water Schemes (PDF 65KB).

This explanatory note has been developed as part of a joint project between South Australia’s five water industry regulators: OTR, EPA, DHA, DEWNR and ESCOSA.
