The Center for Water and Sanitation undertakes research, implementation support and capacity building initiatives in the field of urban water and sanitation. Acting as a thought catalyst and facilitator, CWAS works closely at city, state and national levels to support governments in policy, monitoring and delivering water and sanitation services in an efficient, effective and equitable manner. The Center was established in 2009 with a pioneering project of performance assessment system (PAS) of water and sanitation service delivery in Indian cities. It has grown to cover over 1000 cities across India, enabling informed policy decisions and actions for improvement. Recent work of CWAS includes support to the Government of Maharashtra in implementing Swachh Bharat Mission and Faecal Sludge and Septage Management. This includes support to city governments to address the entire WASH service chain including safe management of waste-water.
