They are both are indulgent & wasteful
The 2010 Hummer H2 on the left gets 3.8 kilometres per litre – and it indulgently wastes valuable natural resources.
The dam on the right loses 3% of it’s total volume every day, and will lose it’s total volume three times over every year due to the effect of evaporation on its naked water surface.
It’s wastes Australia’s most valuable resource.
Water.
How close to disaster do we need to be before we act?
Australia November 2019 | Australia’s worst ever drought
This is a preview of our future
The average farm dam loses 15,000,000 litres of water a year to evaporation.
There are approximately 50,000 dams in Australia
That means we lose 750 billion litres of water every year
Temperatures are getting hotter
And we are receiving less rain
We are headed for big trouble
But there is a simple solution
We help the mining, oil, gas, power industries & major infrastructure projects achieve permanent water security
We provide streamlined water practices & manufactured evaporation management solutions to enable excellence in corporate water stewardship
EVAPORATION MANAGEMENT
WE TOLD A POWER STATION TO ‘CHECK OUT OUR BALLS’
When one of Australia’s largest power stations wanted to stop evaporation losses from their two massive dams – EVAP.CO introduced them to shade balls
Shade balls are small plastic spheres floated on top of a reservoir. They reduce evaporation losses by up to 90% – and prevent sunlight from causing reactions among chemical compounds present in the water.
In 2014 and 2015, our US shade ball partner put 96 million shade balls onto Los Angeles’ largest reservoir. The balls saved 1.7 million cubic metres of water from evaporating during their deployment from August 2015 to March 2017.

EVAPORATION MANAGEMENT
BHP COPPER MINE CHILE
When BHP wanted to more accurately record the evaporation losses from their Chile tailings dam, we talked to them about all the new alternatives
CORPORATE CONSULTING
Water is important to BHP
They were looking for technological solutions to monitor water losses in their Chile tailings dam more frequently and accurately, in order to improve the accuracy of the water balance.
Currrent water loss information is taken from satellite image
analysis and bathymetry, but these measurements do not allow for timely operational decisions because the data is obtained infrequently.
BHP’s challenge was to suggest a better way to measure evaporation – because when we did that, we could better quantify the real impact of the of water losses – and generate a baseline for management to make better decisions.
This solution could then be applied to any tailings dam around the world.
That’s a huge innovation for the global mining industry
