Bagmati is the largest river system in the Kathmandu Valley comprising 57 rivers and rivulets as its tributaries. There are many heritage sites and traditional settlements on its bank that are rich with numerous tangible and intangible heritages, collectively termed as ‘Bagmati Civilization’. One of the significant sites is the Pashupatinath temple area, which is enlisted as a World Heritage site. Bagmati, the holy river of the Hindus and a major source of water for the Kathmandu Valley, has been polluted due to human actions such as settlement along the river, unplanned urbanization in river basin and disposal of untreated sewage and solid waste into the river system. Joint initiation of citizen and government to make Bagmati a pollution free river resulted in formation of a high-powered Committee for Implementation & Monitoring of Environmental Improvement in Pashupati Area back in 2051 B.S., which is now functioning as High- Powered Committee for Integrated Development of Bagmati Civilization (HPCIDBC).
