Drinking water must not be a route for the transmission of pathogens.
Water is not available everywhere and at all times which meets this requirement in the stage of winning.
Contaminated or potentially contaminated water must be treated so that it can no longer transmit pathogens.
The pathogens contained in water must either be filtered out or killed by disinfection.
However, the two processes are not equivalent in the extent to which they eliminate pathogens.
Because of their natural fecal origin bacteria and viral pathogens incorporated in particles and parasites with a very high resistance to external influences (including disinfection) can only be removed reliably by filtration.
Disinfection as conventionally used in drinking water is not capable of killing them reliably.
Disinfection can only kill bacteria and viral pathogens which are individually in free suspension.
Disinfection should be used as in the past to minimise residual risk and not to eliminate demonstrable fecal contamination.
In the case of water with primarily fecal contamination, both processes - filtration and disinfection - must be used to win epidemiologically acceptable drinking water.
Neither process is adequate on its own to ensure acceptable drinking water.
The reliability of filtration must also be monitored.
