Evaporation – how much water do I lose?
Evaporation is the single largest cause of water loss.
Every square metre of water surface loses about 8 litres to evaporation every day in the warmer months.
This means that even a small farm dam of 1,000 square metres will lose 8,000 litres per day. A 100 hectare dam loses 8 megalitres per day, or 56 megalitres every week
The table shows evaporation losses for typical dam sizes ranging up to 100 hectares.
|Dam Area||Evaporation At 8 mm Per Day*|
|1,000 sq m||8,000 Lt||56,000 Lt|
|5,000 sq m||40,000 Lt||280,000 Lt|
|1 hectare||80,000 Lt||560,000 Lt|
|5 hectares||400,000 Lt||2.8 ML|
|20 hectares||1.6 ML||11.2 ML|
|100 hectares||8.0 ML||56.0 ML|
*Typical daily evaporation during the warmer months in most parts of Australia
How much water will I save with Aquatain?
Independent trials using Aquatain have achieved evaporation savings of around 50%. (Copies of trial reports available on request.)
