New Delhi, June 10 -- In a significant overhaul plan for Delhi's water supply, the Delhi Jal Board (DJB) has chalked out a Rs.10,087 crore detailed project to reclaim Yamuna and revamp the city's water infrastructure. Officials said on Sunday that this three-year plan has been presented to home minister Amit Shah and Delhi water minister Parvesh Verma for approval. To be sure, the central government has a separate, long-term plan to clean the Yamuna, and DJB's plan is not connected to that. The most extensive plan of the Delhi government so far, it comprises installing new sewage treatment plants (STPs), river rejuvenation schemes, fixing the broken pipes, and tapping rogue drains. "The city cannot afford piecemeal fixes anymore. This is a consolidated plan that addresses every part of the water cycle - from source to sewer," a DJB official said on condition of anonymity. Of the 3,564mld (million litres per day) of sewage generated daily in the Capital, around 2,951mld is actually treated, despite the city having a total STP capacity of 3,470mld, the report by DJB, which HT has seen, said. DJB now aims to increase that capacity by 862mld through upgradation of old plants as well as construction of eight new ones. Furthermore, DJB documents show that Delhi's major STPs - including the Coronation Pillar, Yamuna Vihar and Okhla - will play a key role in restoring the river's environmental flow. "By September 2026, treated water from these plants will be released downstream of the Wazirabad barrage to help revive the Yamuna. At Coronation Pillar alone, 454mld of treated water is expected to be diverted into the river. These discharges are engineered flows that will reintroduce oxygen into stretches that have long been biologically dead," the official explained. Officials added that the plan also includes fixing the leaks in supply water. The city's daily water demand stands at 1,250mld, but the current supply from DJB is 990mld, with around 260mld shortfall. Nearly half of this supply is lost to leaks, theft, and outdated metering, as per officials. "The immediate focus is on boosting short-term availability. A project involving 452 tubewells is expected to add 26mld by September. Another 50mld will come from the second phase of the Dwarka water treatment plant (WTP), although its raw water source is yet to be finalised," the official said....
