Recycle Rainwater

Since the beginning of human evolution there has been about the same amount of water on earth. This water is in a continual state of cycle and recycle as it has been doing an inestimable number of times. So why the present angst about recycling waste water?

(Some trivia about water is the earth's surface is 2/3 water and 1/3 land. The volume of water on earth is 1,386,000,000 cubic kilometres, 95.6% of it being sea water. Of the freshwater, about 1.74% is snow and ice and 1.7% is ground water. This leaves about 0.6% for all the rest of the water on earth including our rivers, lakes, man-made storage and atmospheric water that falls as rain, etc.)

Sydney's daily news is the state of our fresh water storage is generally about 50% of capacity. Hype and fear caused Sydney to spend a few billion dollars on a sea to fresh water desalination plant that is very expensive to build, very expensive to run, burning mainly coal, using highly polluting and greenhouse gas-producing electricity. This was an isolated government decision.

The present position is: Sydney is holding our own in our water needs, while only scratching the surface of household water saving and water recycling, so is the multi-billion-dollar very expensive pollution-generating desalination plant good value for the money? Could or should this money be spent in a better direction?

The majority of the cities of the world now use some form of centralised and coordinated recycled water system, but not Sydney.

Sydney is located in a natural geological basin known as the Sydney Sandstone Basin. This basin is a natural water catchment area and the present uncaptured rain water runoff is sufficient to satisfy Sydney's present and future water needs many times over each year.

This is the same water source that falls in the designated catchment area so why not call it the Sydney Sandstone Basin Natures Given Catchment Area and think positive about it rather than using the negative name of recycled water? The technology and cost to make this water potable is far simpler and a fraction of the cost of the desalination plant.

To do this right, cheaply and effectively, we do not have to even think about recycled sewage water even though this is done the world over as nature has always done.

There must be many and varied good ideas within the community for the cooperation, action, and drive for this to happen.
