-Understanding Intermittent Water Supply (IWS)-

Intermittent Water Supply (IWS) refers to a piped water service that is available to consumers for less than 24 hours per day, often described as irregular, unreliable, or inadequate. The frequency of intermittency varies, with some systems following a regular rationing schedule (daily or every few days), while others experience seasonal shortages due to increased demand, such as during tourism peaks or hot weather. In some cases, occasional intermittency occurs due to source-related issues, such as lower yields, water quality deterioration, or external pollution. Unlike temporary supply cut-offs for repairs, IWS represents a persistent challenge in water distribution systems.
