Surface Water and Artesian Water – Both Equally Vital!!


Surface Water and Artesian Water – Both Equally Vital!!

Have you ever travelled through rural Australia, and noted that the clear water flowing from the tap had unusual smell? Not an offensive smell, just a different odour? Have you ever indulged in an artesian spa, and experienced the relaxing effects of naturally warm water? The Great Artesian Basin (GAB) lies beneath 22% of our nation, and provides much of inland Australia with water for people, communities, plants and animals. The Great Artesian Basin recharges from rainwater, however the exact rates of recharge in relation to actual use by mankind can only be estimated. Given our variable and reduced rainfall in recent years, one can only speculate on the recharge impact on the GAB. And if one were to compare the GAB water supply of the past with the present, there is an alarming and noticeable decrease in water pressure and lowering of the water tables.

There have been recent attempts to ‘cap and pipe’ artesian water, which means the iconic image of bore water erupting out of the ground at the bore point, and flowing through drains across the countryside is becoming less of a sight in rural Australia. However, we need to expand this scheme to ensure all artesian water is utilised in a sustainable and sensible manner. There have also been recent attempts to auction GAB water. One has to ponder if this is a wise action, given the actual recharge of the GAB is still unproven?
