There is a water ocean beneath deserted central Australia, being accumulated billiards years ago as a part of formatting the geological structure of what is a recent continent called Australia.

The understanding of necessity to preserve non-renewable resources water definitely in Australia is, makes a difference between modern time and timing of even few decades ago.

Simply pumping water from assessable geological structures (rivers, lakes, underground sources) or by deploying engineering solutions used to the same purpose that is water catchments such as dumbs, wells, water tanks etc. –solves no long-term problem but pleases just politicians of the date.

Although applauded as a rational use of resource, personal hygiene/domestic level water savings affect a general picture of scarcity for water not much.
