Water storage in a reservoir or tank that is open to the surrounding air will suffer from evaporation losses. It is the direct contact between water and air that allows evaporation to occur.
Any stored fluid can suffer evaporative losses:
Raw Water or Drinking Water;
Recycled Water;
Irrigation Water or Livestock Water;
Cooling Water and Industrial Process Water;
Hydrocarbons;
Bulk Chemicals;
Fuel and Oil.
Any uncovered storage allows evaporation to occur:
Earthen Reservoirs and Ponds;
Lagoons and Lined Storages;
Concrete Tanks, Steel Tanks and Plastic Tanks.
What Affects Evaporation Rate?
Surface area of water in contact with surrounding air;
Environmental factors (generally can’t be controlled):
Temperature of stored water;
Temperature and humidity of surrounding air;
Wind speed.
How to Prevent Evaporation?
Prevent direct contact between stored water and surrounding air;
Reduction of water surface area in contact with air will lead to a proportionate reduction of evaporation rate and associated losses;
Environmental factors affecting evaporation rate generally cannot be controlled.
Hexa-Cover® – The Answer to Evaporation
The Hexa-Cover® Evaporation Mitigation System reduces water losses to evaporation by reducing direct contact between stored water and air. Unlike some other evaporation mitigation technologies, Hexa-Cover®:
Is low cost, and easy to install;
Does not require operation or preventative maintenance;
Does not consume electricity or chemicals;
Does not require site specific design or supporting infrastructure;
Achieves up to 99% coverage of the liquid surface area;
Allows rainwater collection to continue;
Self-adapts to any storage type or shape;
Self-adapts to any water level in the storage;
Maintains safe and easy access to the water storage;
Is not susceptible to wildlife damage and will not trap wildlife;
Is manufactured in Australian from recycled materials.
The Hexa-Cover® Evaporation Reduction System can be successfully applied to any stored fluid that suffers losses due to evaporation.
