Chemical film slows dam evaporation by 60pc: trials
Posted Tue Sep 4, 2007 2:05pm AEST
Australian laboratory trials of a new technology to reduce evaporation in dams has shown promising results.
Researchers are developing an ultra-thin chemical film to be placed on the surface of dams, and tests have shown it reduces evaporation loss by up to 60 per cent.
The film is made from a special biodegradable chemical that can be applied to dams every few days when evaporation rates are high.
Water authorities in south-east Queensland have calculated evaporation losses are equal to the annual consumption of 1.6 million households.
Project leader Professor David Solomon from Melbourne University told a conference today that the film offers a huge potential.
He says it has low environmental impact and is cost effective. More trials are planned in large public water storages and farm dams.
