Results from monitoring of Indian aquatic resources also show that water bodies, such as rivers and lakes, near to urban centres are becoming increasingly saprobic and eutrophicated due to the discharge of partly treated or untreated wastewater (Central Pollution Control Board, 2010). River Yamuna, which passes through 6 Indian States, receives about 1789 MLD of untreated wastewater from the capital city of Delhi alone. This is about 78% of the total pollution load that flows in to the river every day. As a result the water quality and hydrological character in the Delhi segment of the river is the most polluted as compared to other stretches in terms dissolved oxygen (DO) and biological oxygen demand (BOD). The DO level had decreased to 1.41 from 8.05 in the Himalayan segment and the BOD level has risen to 17.2 from 2.8. This is quite significant as National Capital Territory of Delhi extract about 2500 million cubic metres of water per annum from river Yamuna for domestic, industrial and irrigation purposes
