- Slideshow: National Ganga River Basin Project
The Ganga is India's most important river. Its sprawling basin accounts for one-fourth of the country's water resources and is home to more than 400 million Indians, about one-third of India's population. The National Ganga River Basin Authority has the mandate to develop a multi-sectoral program for ensuring that after 2020 no untreated municipal or industrial wastewater will be allowed to flow into the Ganga. The World Bank is supporting the government of India in its efforts to achieve this national goal.
