Upgrading intermittent to continuous water supply in India (2009-2012)

2156444_origAn interdisciplinary group of researchers from the University of California, Berkeley (CA, USA), the Center for Multi-Disciplinary Development Research (Dharwad, India), and SDM College of Engineering (Dharwad, India), worked together to evaluate the conversion from intermittent piped water supply to continuous supply (’24×7′) in Hubli-Dharwad, India. In Hubli-Dharwad, 10% of the population was switched to 24×7 supply in 2007/2008, and the remaining residents continued to access piped water intermittently (supply every ~5 days). We studied the impacts of this conversion on water quality, health, water quantity, and household economics. The papers resulting from this project are below.
