| There is a spell check on Googles toolbar, it works well in conjunction with yahoo, there is no need for errors, I wish there were better grammar checkers, I'm lousy at the stuff. |

| Southern- You have misled yourself and others about the aquifer and waterproofing program currently being developed in the northern suburbs, It has no real potential as a major water resource, There was no official claim it would be ! It is of limited value ! You have read about it and made your own exaggerated claims about its uses and effects ! You are blind to reality caught up in your own imagination ! You Southern are a Fool ! |

| so trandiode, can you elaborate as to why the idea has no potential as a water resource? |

Heiron do you understand the principle behind the construction of underground aquifers and waterproofing techniques? If you did you would realise that there are only a few areas in and around Adelaide it can be feasible due to geological criteria regarding underground storage aquifers, The second problem is catchment ! The catchment needs to be close to the aquifer, that limits potential sites even further, next is the amount of water you can realistically expect to hold in these underground aquifers ! Some northern suburbs have the necessary geological and catchment criteria for its use, but it is limited to watering of parks and ovals due to its own inherent limitation on the amount of output of usable water it can produce ! It is a very limited system and an expensive one at that ! |

Well trandiode, I do have some understanding of both the Geology and they Hydrogeology of the subsurface structures in and around the Adelaide region. Once the limestone has been penetrated, in certain areas, usually grinitic sands in layers of several meters thick are immediately available. The sands act as filtering agents to a degree, to help hold and remove dissolved solids from the groundwater. Underneathe the sands, often at relatively shallo depths (100 mts or less), lies Granite, a non flowing pyroclastic material, which is readily faulted at intervals, cpapble of holding many many gigalitres of water also. In fact the holding capacity of the area is almost beyond comprehension. Heres an intersting fact for you. 93% of the planets water is actually underground.....
As to the recharge areas having to be close to the bores, well that is not factual either. The recharge bores, depending on design criteria, can be in a radius of several kilometers of the catchment area, depending on pumping criteria. It is however preferable to have the rahcrge bores close to the stormwater harvesting area.
The idea has merit, and is indeed already being used with great sucesss, not only here in Australia, but also around the world. In fact, Australia has only recently "caught on" to theis in the last few generations.
It makes a great deal of sense to store harvested stormwater underground, safe from evaporation and also allows the bnatural geological formations, ie sedmentary and alluvial sands, to act as filtering agents, rather than allow that stormwater to run out to sea to be lost untill the next rainfall cycle..
I dont understand your objections to the principles of this technlogy........????? |

As to being a limited system, wel that is limited firstly by natural recharge and then by artificial recharge, ie stormwater harvesting..... Groundwater is an often speculated upon but not entirely understood resource. You need to have first hand experience in the area to completely understand it and the way the whole hydrogeological process works.
Heres another interesting litle fact.
There is actually MORE water on the planet now, than there was last year...... That is because, as comets enter our atmosphere, they are burnt up by friction, thus the "shooting stars"....what are comets often made of? ICE....they shed many millions of litres of water into our atmosphere. We have a closed system. Our water doesnt leave our atmosphere. It evaporates, cause clouds, then rain, then the cycle begins again.... |

yes it does and if only we had the system already established after brilliant sept rainfall... |
