Measure: FiltersInAerationProcesses


All air for aeration purposes in water treatment plants and water storage tanks should be filtered. Thus it is aimed to prevent contaminations induced by entering air by the provision of physical barriers. The aim is to ensure an ongoing high quality of the supplied water.


Filters should be installed at every air intake for aeration purposes. Furthermore, no openings for aeration purposes should be built directly over the water surface to prevent that attackers can easily induce dangerous substances or that dangerous substances are induced in a natural way.
