Intermittent to continuous piped water supply

Evaluation of the conversion from intermittent to continuous piped water supply in Hubli-Dharwad, India

In 2010, we set up a study to evaluate the conversation from intermittent piped water supply to continuous supply (’24×7′) in Hubli-Dharwad, India, where 10% of the population was switched to 24×7 supply and the remaining residents accessed piped water intermittently. We studied the impacts of this conversion on water quality, health, and household economics. This also provided us an opportunity to study features of an intermittent supply, including the mechanisms leading to contamination in these systems and the quantities of water consumed by households with unreliable water delivery. The papers resulting from this project are below, with more on the way.
