1.3 Fog harvestingTears should be repaired immediately to avoid having to replace theentire panel. Algae can also grow on the surface of the mesh net afterone or two years of use, accumulating dust, which will cloud thecollected water and cause offensive taste and odor problems. Themesh net should be cleaned with a soft plastic brush as soon as algalgrowth is detected.• Maintenance of collector drains. A screen should be installed at theend of the receiving trough to trap undesirable materials (insects,plants, and other debris) and prevent contamination of water in thestorage tank. This screen should be inspected and cleanedperiodically.• Maintenance of pipelines and pressure outlets. Pipelines should bekept as clean as possible to prevent accumulation of sediments anddecomposition of organic matter. Openings along the pipes should bebuilt to facilitate flushing or partial cleaning of the system. Likewise,pressure outlets should be inspected and cleaned frequently to avoidaccumulation of sediments. Openings in the system must be protectedagainst possible entry of insects and other contaminants.• Maintenance of cisterns and storage tanks. Tanks must be cleanedperiodically with a solution of concentrated calcium chloride to preventthe accumulation of fungi and bacteria on the walls.• Monitoring of dissolved chlorine. A decrease in the concentration ofchlorine in potable water is a good indicator of possible growth ofmicroorganisms. Monitoring of the dissolved chlorine will help toprevent the development of bacterial problems.Figure 7: Locations Where Fog Harvesting Has Been or Can BeImplemented.http://www.oas.org/usde/publications/unit/oea59e/ch12.htm (4 of 16) [1/13/2005 12:49:10 PM]
