Safety of the water supply system in the absence of desinfection residue

Abstract

The paper focuses on the drinking water supply with public water mains without the use of disinfectant residues in the transported water. This method of delivering drinking water can only be considered if a sufficient number of functional barriers are present in the distribution system to prevent the penetration of pollution into the transported water. One of these barriers is, for example, a good technical condition of the water-supply system. The security of water supply without disinfectant is ensured by an initial assessment of the suitability of the water system for this mode of operation, risk analysis and network monitoring in selected critical points of the system.
