Non-revenue water is a challenge.

Water pollution is a major environmental issue in India. The largest source of water pollution in India is untreated sewage. [1] Other sources of pollution include agricultural runoff and unregulated small-scale industry.

The ash is dumped into ponds, from which a slurry is filtered, mixed with domestic wastewater, and then released into the Pandu River. Fly ash contains toxic heavy metals such as lead and copper. The amount of parts per million of copper released in the Pandu before it even reaches the Ganges is a thousand times higher than in uncontaminated ...
Water scarcity in India is an ongoing water crisis that affects nearly hundreds of million of people each year. [ 1] In addition to affecting the huge rural and urban population, the water scarcity in India also extensively affects the ecosystem and agriculture. India has only 4% of the world's fresh water resources despite a population of over ...

India accounts for 18% of the world's population and about 4% of the world's water resources. One of the proposed solutions to solve the country's water woes is the Indian rivers interlinking project. [ 2] Some 80 percent of its area experiences rains of 750 millimetres (30 in) or more a year. However, this rain is not uniform in time or geography.
