The Commission has released its final decision on SA Water’s revenues for the three-year regulatory period, 1 July 2013 to 30 June 2016.

This decision sets out the maximum revenue per unit sold that SA Water can recover from its drinking water and sewerage customers over the regulatory period.

SA Water is responsible for setting specific prices (such as supply and usage charges) for residential and non-residential customers; however, those prices must comply with the average revenue caps in the Commission’s Final Revenue Determination.

The Final Revenue Determination results in a nominal reduction in SA Water’s current average drinking water revenue of 5.5% per cent from 1 July 2013; this represents a real (inflation adjusted) reduction of 7.8%. SA Water’s average nominal sewerage revenues from 1 July 2013 will increase by 1.6%, which is a 0.9% real decrease.

In 2014/15 and 2015/16, the average revenue from both services will be allowed to increase with the annual change in CPI only.
