Pool Covers & Evaporation

Love them or hate them, there’s no denying that a pool cover can save massive amounts of water.

Just how much varies depending on a number of factors (such as the surface area of the pool, the amount of wind, shade, water/air temperature). Anywhere between 2mm and 10mm of water every day is seen as an acceptable water loss – but this all adds up – and without rain or top ups, a pool can easily lose its entire volume of water – every year!

The single most effective thing a pool owner can do to save water is to buy (and use) a pool cover. To be honest, it doesn’t even have to be a proper pool cover – any sort of covering will help prevent evaporation – it’s just that a pool cover will be more effective, will last longer, and will be easier to use than say – cling wrap or builders plastic.

So how does it work? It’s all about evaporation. Evaporation is what happens when water turns into gas (such as steam, when you boil the kettle). Obviously your pool is not boiling like a kettle, but the theory is the same. When the water inside your pool is warmer than the air around it, evaporation will occur.  Without a cover, that water vapour will release back into the atmosphere – but with a pool cover in place, it can’t escape, and stays in your pool, where it belongs.

ABGAL Oasis Solar Pool Covers have been independently tested and proven to stop up to 99.84% of evaporation. They are Climate Care Certified, Smart Approved WaterMark Licensed, and Water Wise accredited, complying with water saving standards across all drought declared Australian states and territories.

Garry Long has been working in the Australian pool industry since 1978. A qualified canvas goods maker with a passion for innovation, he was inspired by the technology behind the sails used in America's Cup racing sails, and adapted and applied it to the pool industry at ABGAL. In 1990 ABGAL were the first company in Australia to use a single ply robotic cutting system to fabricate vinyl products. In 1993 Garry developed a 3D measuring system for complex shaped inground pools, which continues to be used today. Garry was President of the Australian Canvas & Synthetic Products Association in 2007-2008, and is the Managing Director at ABGAL Liners & Covers.
