Descriptif
Although constructed wetlands have been widely used in Europe and America for the treatment of wastewater prior to disposal, they have not yet been applied to the profound and chronic problems of water quality control that affect large areas of developing countries, especially in regions affected by water shortage. The problems of water pollution are getting worse due to the greater use of agro-chemicals by farmers, to urban and industrial efflluents from growing cities entering rural water conveyance systems, and intensive farming around cities due to population growth. There is an urgent need for appropriate and sustainable solutions that will help countries to maintain agricultural and industrial output and still maintain water quality standards. The constructed wetlands technique has many merits that make it particularly suitable for this purpose - simple, relatively easy to explain and replicate, relatively inexpensive, environmentally sound if managed properly. There is a lot of interest in the technique, but people in developing countries have not been able to initiate any research or development work. The UK has a leading position in Europe and round the World in the use of the technique. The development of a successful system for use in the context of tropical climates and the problems of developing countries in controlling pollution in their water conveyance systems, would provide an inexpensive and appropriate technique that could be speedly taken up.
