New technology to reduce evaporation from large water storages

Waterlines report No 80 - June 2012

Waterlines 80: New technology to reduce water evaporation from large storagesEvaporation from water storages is a major issue affecting agricultural regions of Australia with annual losses potentially exceeding 40 per cent of water stored. Loss of this water can lead to reduced agricultural productivity and adverse environmental impacts.

The Cooperative Research Centre for Polymers investigated the development of a new ultra-thin product to form a film on the surface of the large water storages to reduce evaporation. This report describes the laboratory work and field testing undertaken during 2010 and 2011 to evaluate and further optimise the product.

The report gives a concise summary of the background science and a description of the laboratory techniques used to investigate the ability of the new chemical formulations to significantly reduce evaporation from water surfaces.
