Tapping a water strategy
GOLD Coast Water's Five Taps Strategy aims to ensure the Gold Coast has an adequate water supply in the future. This week we look at the Hinze Dam.
IF the Gold Coast wishes to rise above predicted water shortages, it needs to stop its heavy dependence on the Hinze Dam.
The relentless drought that has dehydrated the Gold Coast from 2002 triggered a review that revealed our rapidly growing area's current water supply from the Hinze and Wivenhoe dams would eventually drop to 190 megalitres a day.
However by 2056 an estimated population of 1.2 million will be consuming 465 megalitres a day.
To cope with the increased demand, the Gold Coast City Council has unveiled the Five Taps Strategy, underpinned by the concept of diversity to make the Gold Coast more resilient to drought and terrorism.
While the Hinze Dam can be raised further, extensive hydrological assessments of the catchment show that a significant amount of water from the catchment is already captured by stage two.
Stage three is still under consideration by the Gold Coast Waterfuture Advisory Committee but it can only provide up to six years of water for the growing city.
Last week the Hinze Dam's capacity stood at 63.66 per cent, much higher than 45.19 per cent recorded at the same time last year.
Weather forecasts along the Gold Coast from now until next month indicate there is a 60 to 70 per cent chance of above average temperatures and less than a 50 per cent chance of receiving average rainfall.
