-Water sufficiency is a matter of national survival & imported water and local catchment water currently meet more than half of our water demand, but both sources depend heavily on weather conditions
--> WHY INCREASE?: - priced water to reflect higher costs of desalination and NEWater production because every additional drop of water has to come from these two sources
-cost of water production and transmission has increased as we build more desalination and NEWater plants, and lay deeper pipes through an urbanised environment.
-last revised in 2000, almost 20 years ago = update to reflect cost of water supply
