Yamuna River originates from the Champasar glacier in the Himalayas and flows through 1,376 kilometers and merges with the Ganges River in Allahabad. The most polluted part of the Yamuna starts from the Wazirabad barrage, a type of dam, to Okhla barrage, a 22-kilometer stretch in New Delhi. About half of Delhi’s sewage flows untreated into the Yamuna , ruining it for farmers and wildlife downriver. The 22-kilometer (14-mile) stretch of the river that flows through Delhi has a dissolved oxygen content, a measure of a river’s health and ability to support life, of zero in some areas [2, 3, 5]. Beside the normal role in agriculture the Yamuna is considered a holy river for Hindus and associate with the Lord Krishna [3, 4]. Yamuna, is also the lifeline of Delhi. Though the river caters to 70% of Delhis water needs, the city s ever-growing demand and dumping of millions of liters of sewage and untreated waste by 19 canals, is slowly killing the river .
