Microorganisms like bacteria, virus and protozoa are naturally occurring in the environment. They are in fact regarded as the oldest living organisms that exist in today’s environment. Thus, eradication is impossible as their absence would cause a rift in the natural balance of ecology.
The government’s courses of action therefore include, instituting root-cause barriers against the enumerated causal factors that contribute to the spread of waterborne diseases. Prevention on a community level, on the other hand, includes but is not limited to the following:
(1) The regular application of disinfectant into the distribution line of drinking water, as a means to render the microbes inactive or unable to produce disease-causing substances. This method, however, can be affected by the presence of solidified materials present in the water; thus, to be effective, impurities should be first removed. It is likewise suggested that adequate amounts of disinfectant be retained in the drinking water to serve as a barrier against potential problems.
(2) Maintaining barriers between the source of public water supply and the sewage water or storm water drainage and its outlets.
(3) Observing periodic flushing of the distribution system to eliminate or prevent static water in slow-flow areas.
(4) Ensuring systematic and regular repairs and maintenance of the distribution lines (e.g. broken mains, pipes, valves and fittings including service meters).
(5) Setting standards and criteria for results of treatment techniques and issue regulations for the monitoring of contamination levels of public water sources, particularly after the occurrence of a power failure or supply stoppage.
