This article analyses the water, sanitation and hygiene situation in slum households and compares it with the non-slum urban households using data from the 2011 Census. It argues for a shift from the mere water supply coverage to an emphasis on quality water distribution. Intermittent water supply coupled with poor sanitation contributes to higher health risks. Promoting point-of-use water treatment and basic hygiene practices on safe handling and storage of water are important preventive health interventions. This article advocates for a shift from availability of infrastructure to delivery of service-level outcomes.
