The Tribunal has decided that Sydney Water’s overall revenue should increase in line with movements in the consumer price index (CPI) in each year of the determination period. However, the prices it can charge for water services will be restructured so that usage charges constitute a greater proportion of customer water bills. The water usage price will increase by 1 per cent above the rate of inflation in both 2003/04 and 2004/05, while the water service charge will increase by 1 per cent less than the rate of inflation in each year.
