The World Chlorine Council has partnered with Andrew Robertson, P.E. of Water Engineers for the Americas to produce a set of three, easy-to-use cistern disinfection posters.
The posters provide simple, pictogram directions for cleaning and disinfecting cisterns, which are vats used to collect and store drinking water in remote areas and developing countries.
The three posters provide stepwise instructions for cleaning and disinfecting cisterns using sodium hypochlorite (bleach), calcium hypochlorite (“HTH”), and sodium dichloroisocyanurate (“NaDCC”), respectively.
Mr. Robertson, who volunteered his time to help develop the posters based on his extensive field experience, stated, “From hurricane relief to COVID, the need for emergency disinfection of household water supplies is now more acute than ever before. The instructional posters provided by the World Chlorine Council provide invaluable guidance to families in need, regardless of what language they speak”.
The posters may be downloaded for free here.
