INDIAN GEOGRAPHY

Detailed explanation-1: -The Ganga’s mainstem runs through 50 major Indian cities, almost all of which have a population of more than 50, 000 people. These towns and cities generate some 3 billion litres of sewage every day, only a fraction of which is treated before it reaches the river.

Detailed explanation-2: -The main Rambha drain here dumps 152 million litres of domestic and industrial wastewater directly into the Ganges every day. A much larger city next to Rishikesh, also on the banks of the Ganges. The Upper Ganges Canal, an irrigation system for the Doab region to the west, also splits from the main river here.

Detailed explanation-3: -Every day, around three million litres of sewage is emptied into the Ganges – and only about half of that has undergone any kind of treatment. The river’s waters are so dirty that it’s considered one of the most polluted waterways in the world.

Detailed explanation-4: -Floating ingredients such as faeces, human and animal rotting flesh, and modern plastics add to the 2, 723 million litres of sewage pumped into the Ganges’ tributaries on a daily basis.
