Using Water Tanks to Supplement Dam Water Storage

Dams and watering holes play a crucial role in rural Australian water storage, and you might be surprised to learn that there are over 2 million dams across rural Australia. These dams have a combined storage of over 8000 gigalitres of water. That’s an incredible 8,000,000,000,000 (eight trillion) Litres of water.

However, in the drier months, more than 50% of a dam’s stored water can be lost to evaporation alone, in just four months. As dry spells across Australia get longer, and rainfall in many areas is proving less reliable, dams are becoming a less dependable water storage solution, especially for those with livestock or crops.
Installing a water tank, to supplement the water storage available in a dam is a great way to safeguard your stored water for the warmer months, and even make the most of your water harvesting efforts. Where many dams overflow in wet seasons after sustained rainfall, pumping some of this stored water into a rainwater tank (or several) can also ensure you are able to capture more of the water falling on your property.

Southern Cross Windmills

Windmills have long been used in rural areas to pump water from aquifers deep below the ground or from dams into watering troughs or into water tanks with no effort required. What has always made windmills so effective and accessible is their ability to pump water day or night with nothing but a light breeze.

Using a windmill to pump water from a dam to a water tank during the months when rainfall is at its best, and perhaps even causing dams to overflow, can divert some of this water to a form of water storage where evaporation will not reduce your water storage levels.

Not only does this sure up your water storage, but can also keep the dam at a reasonable level, maximising your total water harvesting capacity.
