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 gases including water vapour. 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
A liquid ‘blanket’ to reduce evaporation!
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%.
