Inclining tariff supported: In one of its key conclusions in the
executive summary of its final report into water and wastewater pricing
in Western Australia, the ERA said these wastewater prices should be
determined as an inclining tariff.
Part retention of charging according to capacity to pay: Such an approach would increase transparency while partly retaining the principle of charging according to capacity to pay.
How usage charges should be structured: The ERA also said that
prices for water services should be structured so that usage charges
were set at levels to reflect the estimated cost of developing new
water resources to meet water demand.
