According to the Central Pollution Control Board (CPCB) report, 61,948 million liters of urban sewage is generated on a daily basis in India. Only 38 percent of this, cities have an installed sewage treatment capacity. more than 38,000 million liters of wastewater goes into the major rivers, water bodies and even percolates into the ground every day.
Around 302 polluted stretches on 275 rivers have been reported recently. The top five states showing a maximum number of polluted stretches are Maharashtra, Assam, Madhya Pradesh, Gujarat, and West Bengal. Estimated polluted riverine length is 12,363 km, which is almost five times the length of Ganga main stem.
Since cleaning Ganga and its tributaries has always been the priority for the Central government, hence the monitoring of the pollution of the rivers and availability of data in the public domain is accessible. An umbrella programme Namami Gange was created in 2015 and a budget of Rs 20,000 crore was allocated for 2015-2020 and the cleaning of the river and its tributaries started. Namami Gange was even given a status of authority in 2016.
