This article presents the findings of research comparing two modes of water supply, continuous water supply (CWS) versus intermittent water supply (IWS), in distribution systems in four cities in India. This realistic appraisal of the behavior of water distribution system design parameters, including pressures, per capita consumption, and peak factors during these two modes of water supply, taking into account the intangibles associated with the two systems, indicates that these parameters remain within the design limits during CWS. A high peak factor during IWS affects pressure and flow in the distribution system. IWS practice does not promote public hygiene and is, therefore, not recommended from the standpoint of public health safety as well as consumer convenience and satisfaction. Shifting to a CWS mode provided that the water system is metered and that nonrevenue water is within a permissible limit is recommended. Includes 9 references, tables, figures.
