Treat used water, don’t waste it: Our water security may depend on recycling this vital resource
The promise of recycled water: India’s urban areas alone generate nearly 72,000 million litres per day of sewage, yet only about 27,000 million litres is treated daily. A 2023 study by the Council on Energy, Environment and Water (CEEW) estimated that if treated water is used for irrigation alone, it could irrigate 1.38 million hectares, generate ₹96,600 crore in agricultural revenue and recover nutrients worth ₹5,000 crore. That is over $11 billion of potential value waiting to be tapped.
