Water and sewerage acts, regulations and standards

Water Industry Act 2012

The Water Industry Act 2012 and its associated regulations provide a legislative framework to ensure that South Australian consumers have safe, reliable and quality water supplies, sewerage services and installations. The Act helps plan water supply and demand and provides guidance for the water industry through:

  • licensing
  • price regulation
  • regulating customer service standards
  • informing technical standards for water and sewerage infrastructure, installations and plumbing
  • performance monitoring of the water industry
  • other measures relevant to using and managing water.

Water Industry Regulations 2012

The Water Industry Regulations 2012 define licensing, technical and safety requirements for water industry entities. The regulations also address the protection and use of water and sewerage infrastructure and equipment, and water conservation measures.

Water and sewerage infrastructure technical standards

The Technical Regulator publishes technical standards for people who design, install, inspect, alter, repair, maintain, remove, disconnect or decommission water and sewerage infrastructure, as defined by the Water Industry Act 2012.

Infrastructure Standard

The Technical Regulator has published an Infrastructure Standard which adopts the Water Services Association of Australia (WSAA) codes as the principle minimum Standard for water and sewerage infrastructure.

The intent is not for legacy assets to be updated, but that going forward, WSAA codes, supplementary notices and supporting documents which are equivalent to or exceed WSAA requirements shall be used for any design, installation, inspection, alteration, repair, maintenance, removal, disconnection or decommissioning of water and sewerage infrastructure.

The WSAA codes complement standards, codes and guidelines in current legislation – a copy is available for viewing at the Office of the Technical Regulator.

By formalising the WSAA codes as the Infrastructure Standard, the Office of the Technical Regulator (OTR) recognises that the WSAA codes have gone through a peer-review process and are widely accepted for the requirements of water and sewerage infrastructure.

If utilities produce supplementary notices and supporting documents which are equivalent to or exceed WSAA requirements, then these will be recognised as suitable as part of this standard.

WSAA codes

Codes and extracts are available from the WSAA shop.
