Introduction
• According to a census conducted in 2011, Kathmandu metropolis alone has 5.2 million inhabitants, and the agglomerate has a population of more than 7.5 million inhabitants. The metropolitan city area is 50.67 square kilometers (19.56 sq m) and has a population density of 123,225 per km².
• The city stands at an elevation of approximately 1,400 meters (4,600 ft) in the
bowl-shaped Kathmandu Valley of central Nepal. It is surrounded by four major mountains: Shivapuri, Phulchoki, Nagarjun, and Chandragiri.
• Kathmandu valley, the main urban centre of Nepal, the chief concern is contamination from sewage lines, septic tanks, open pit toilet and surface water has been polluted by direct disposal of solid waste.
• The main river of Kathmandu valley is Bagmati River which meanders through the lands of the valley merging with many primary tributaries viz. Bishnumati, Dhobi, Manohara, Hanumante, Tukucha, Kodku, Godavari, Nakhu, and Balkhu, finally exiting from Chovar
Kathmandu Valley
Bagmati in the Past
• Kathmandu valley civilization is known as Bagmati
Civilisation
• Bagmati and Bishnumati have religious importance as
major temples and buddhist shrine are situated at the
river banks

irrigation of Kathmandu valley and other human purposes
• River banks are ritual procession places at the time of
human birth and death.

past

Current condition of Bagmati
• Kathamandu is famous for its alluvial soil but now days
no barren land can be found due to increase number of
infrastructure and buildings. Population growth is the
major cause of Bagmati river pollution.
• Bagmati is polluted due to solid waste ,sewage waste and
human encroachment in the river banks
• River without water is the source of different diseases
• River bank settlement from the people migrating from all
over the country is polluting river more from their activities
Current condition
Policy taken to prevent pollution in Bagmati
• KMC has made compulsory provision of septic tank within
the building whiles constructing any building.
• KMC and government has removed the inhabitant and
destroy the infrastructure made by them encroaching river
banks
• Construction of separate sewage drainage in river banks
preventing sewage waste directly flowing to the river.
