Experiment with water

Syllabus: GS-III, Subject: Environment, Ecology and Disaster Management, Topic: Pollution, Issue: Water Pollution

Drinking water issue:

  • Only 10% of Indian cities meet drinking water standards.
  • Water quality degrades in distribution networks due to old pipes, sediment buildup, and pathogen accumulation.
  • The demand for packaged drinking water (PDW) is rising as a result.

The way ahead:

  • Reconsidering treating large quantities for drinking when only a fraction is used.
  • Segregating water for drinking and other domestic uses
  • Decentralized treatment and non-pipe delivery.
  • Bengaluru and Delhi are experimenting with water ATMs to address water crises.
  • More experiments and technological advancements are needed.
