The report “Waste to Worth: Managing India’s Urban Water Crisis through Wastewater Reuse” was released jointly by the Centre for Science and Environment (CSE) and the National Mission for Clean Ganga (NMCG).
India currently treats only 28 per cent of the 72,000 million litres of wastewater generated daily.
The Ministry of Jal Shakti mandates that cities recycle at least 20 per cent of the water they consume.
Uttar Pradesh leads in untreated wastewater volumes, followed by Maharashtra, Karnataka, Rajasthan, Tamil Nadu, Delhi and Haryana.
However, several states have implemented progressive policies.
Tamil Nadu has prioritised industrial and urban greening applications.
Cities such as Nagpur, Bengaluru and Chennai offer successful examples of the wastewater reuse.
Nagpur supplies the treated wastewater to power plants, reducing the freshwater consumption.
