Water Evap

Water Evap calculates your water savings by applying the product WaterGuard™

Water Evap calculates your water savings ( both in water and financially ) by applying the product WaterGuard™ to your water supply.

Why is this relevant?

Water losses from evaporation are huge: a 10 hectare dam (25 acres) can lose up to 800,000 litres each day in summer, or more than 5 million litres per week.

Trials with WaterGuard™ have achieved evaporation savings of at least 50%.

Water Evap picks up your location, surface area of your dam across the year, price you pay for water and can then calculate the incredible benefit you get from WaterGuard™.

WaterGuard™ is a unique liquid which spreads over the surface of water to form a very thin film and reduce evaporation.

WaterGuard™ is produced from polymers which are highly impermeable to water vapour, but still lets oxygen and carbon dioxide through. In the WaterGuard™ formulation, these polymers repel each other strongly when they come in contact with the water, resulting in a strong spreading action across the surface.

A liquid ‘blanket’ to reduce evaporation!

Is WaterGuard™ Safe?

The components of WaterGuard™ are safe chemicals, and many of them are used in food and pharmaceutical applications. An application for certification of WaterGuard™ for drinking water is currently underway.

Rain, Wave And Wind Action?

Once the film is in place, it is very resistant to disturbances. It will move around slowly over the surface, but will not build up at one end of the water body. In the event of rain, the blanket will not be affected as it will allow the rain to go through without disturbing the film.

Application Methods

WaterGuard™ can simply be poured on to the water directly from the drum, and it will spread rapidly across the surface. For larger applications, it can also be applied by air. After an initial loading dose, a top up dose every two weeks maintains the evaporation protective effect of Waterguard™.
