Indian cities are facing acute water scarcity, prompting urgent calls for decentralized wastewater recycling and rainwater harvesting. Experts emphasize transitioning from linear water consumption models to circular economies, treating wastewater as a resource rather than refuse. Policy interventions focusing on mandatory water recycling in urban planning, reducing non-revenue water, and community-led conservation are critical for ensuring long-term municipal water security.
“Cities are running out of water because they pump it out from the ground, use it once, and throw it away as dirty sewage. Experts say cities must start acting like nature: clean the dirty water locally and use it again for things like gardening and factories, so we don't need to pump as much fresh water.”
Urbanization, their problems and their remedies.
Decentralized Wastewater Treatment Systems (DEWATS) treat wastewater close to the source of generation rather than transporting it through miles of pipes to a massive central plant. This reduces infrastructure costs, energy consumption, and makes recycled water immediately available for local non-potable reuse.
Which of the following best describes the concept of a 'Circular Water Economy' in urban management?
In municipal water supply terminology, what does 'Non-Revenue Water' (NRW) mean?
