SA Water regulatory determination 2024

SAWRD24 banner


The Commission will make a new regulatory determination to apply to the water and sewerage retail services provided by SA Water Corporation (SA Water) from 1 July 2024 to 30 June 2028: SA Water Regulatory Determination 2024 (SAWRD24). The regulatory determination sets the maximum revenues that SA Water can earn from its customers over that four-year period, and the service standards it must deliver for its customers.

The regulatory determination, while for a four-year period, is made in a long-term context:

  • The four-year expenditure proposals must relate to (and should be drawn from) SA Water’s existing long-term asset management, financing and service delivery plans.
  • Those plans, in turn, should have been developed through ongoing, transparent and genuine customer, community and stakeholder engagement.

In developing the maximum revenue cap, the Commission analyses SA Water’s proposed expenditure, and forms a view on the overall prudent and efficient expenditure required to deliver services. The Commission does this so that the revenue cap is based on the lowest sustainable cost for SA Water to efficiently deliver its essential services.

The SAWRD24 Framework and Approach sets out the key timing, process and governance matters, for the regulatory determination process.

Guidance papers will be released throughout the review process to clarify the Commission’s expectations for SA Water for all stakeholders.

Timing for this review and upcoming consultation opportunities

While the Commission remains responsible for making the final regulatory determination, the review process will involve multiple opportunities for stakeholders to be involved prior to that final determination.

Input from a diverse range of stakeholders is important, as it helps the Commission to make better informed and more inclusive decisions. The Commission will therefore draw on the full range of evidence provided by all stakeholders in making the final determination.

Current stage: SA Water is developing a Regulatory Business Plan

A key element of the regulatory determination process is the development of a Regulatory Business Plan by SA Water, which details its proposed expenditures and service outcomes for the four-year regulatory period. The Regulatory Business Plan must contain sufficient evidence for the Commission and stakeholders to understand and engage with SA Water’s proposals.

SA Water must submit its Regulatory Business Plan by 3 July 2023.
