Water and sanitation

A high priority is given to safe drinking water to prevent the major risk of waterborne diseases. The major method to accomplish the goal is with chlorine, which is readily available, easily used, inexpensive, and highly active against all waterborne pathogens. It needs to be available for point-of-use in practical forms of free chlorine, as liquid sodium hypochlorite, sodium calcium hypochloride, and/or bleaching powder. The amount given should produce a concentration of active chlorine at 0.2-0.5 mg/l. This can be determined using a readily available test kit. The recommendation is for at least 20 liters of clean water per person per day. There also needs to be attention to adequate water containers, adequate cooking utensils, and clean latrines as additional methods to prevent water- and food-borne epidemics.
