With the help of Water and Sanitation Program (WSP), the Department of Drinking Water and Sanitation has collected some models of good practices from different parts of the country. Care has been taken to ensure these are drawn from as many states as possible. In addition, the good practices identified cover a variety of areas ranging from improved service delivery, operation of multi-village schemes, efficient operation and maintenance, ensuring water quality, measures to ensure source sustainability, pioneering efforts for waste water management, effective communication practices that have been adopted and institutional reforms at state level that have been tried out.
