Description
Radhey Shyam Tyagi, with two colleagues, lays out a 2026 plan for Delhi to close a large water gap and clean its rivers. The city faces a shortfall near 2,000 million litres a day as growth and climate shifts strain supply. Much of its water comes from other states or from the ground.
The plan uses official data, site visits, talks, and scenario models to map a phased path to self-reliance by 2045. Filtered supply now stands at 4,540 million litres a day against demand of 6,540. By 2045, demand could reach 10,880 to 14,797, based on the norm used. Reuse of wastewater, cuts to leaks, rain capture, and ground recharge could lift supply to near 14,928. Random runs gave a 90 percent band from a 1,200 shortfall to a 2,500 surplus.
