Water costs need to rise, sewerage to fall: ERA

A further 4 per cent rise in metropolitan water usage charges will be needed for the 2019 financial year to ensure pricing is cost reflective, according to a draft report by the Economic Regulation Authority.

The report, which is reviewing efficient pricing at Water Corporation, recommended the increase on top of a 6 per cent rise for the 2018 financial year recently gazetted by the state government.

But it would not be entirely bad news for households, with wastewater costs to fall by 41 per cent and drainage to be reduced by 4 per cent, which the authority calculates would leave the average family better off overall by $260 per year.
