Why in news
The Indian Plumbing Association urged a shift from supply-side augmentation to efficiency-led water management to address the projected doubling of water demand by 2030.
Background
The Indian Plumbing Association highlighted that over 85% of Bengaluru's lakes are eutrophic. The association proposed solutions including smart plumbing systems, greywater reuse (e.g., ITC Hotels' Sunya Aqua program), and efficient bathroom fittings.
Facts for Prelims
- FactProjected water demand in India is expected to double by 2030.
- PlaceBengaluru's lakes: Over 85% are reported to be eutrophic.
- FactBengaluru relies heavily on the Cauvery river for piped water supply.
- SchemeSunya Aqua: A greywater reuse initiative by ITC Hotels.
For Mains
Q. Discuss the necessity of transitioning from supply-side augmentation to demand-side management to ensure water security in rapidly urbanizing Indian cities.
Dimensions to cover in your answer
- Resource depletion: Rapid eutrophication of urban water bodies due to unsustainable extraction
- Infrastructure gap: High energy intensity of current piped water systems vs decentralized greywater reuse
- Policy shift: Moving from large-scale river diversion to smart plumbing and efficiency-led conservation
Keywords: Supply-side augmentation · Eutrophication · Greywater reuse · Water security · Smart plumbing
