Hidden drain uncovered
City engineers have uncovered and desilted the Delhi Gate drain for the first time in about 40 years to reduce chronic monsoon flooding near ITO and central Delhi — a practical move that changes how old-city neighbourhoods cope with seasonal water. The Indian Express reports this work is aimed specifically at easing ITO-area flooding ahead of the rains and could improve walkability and access around the old city (indianexpress.com).
Delhi just lifted the lid on a drain that had been buried under concrete for about 40 years, and the target is a place almost every commuter in the city knows: the flooded roads around Income Tax Office, the traffic junction called ITO. Engineers opened the covered stretch inside Samta Sthal and started deep desilting before the 2026 monsoon. (indianexpress.com) This is not a new drain. It is an old storm-water channel called the Delhi Gate drain, and one section of it had been sealed with reinforced concrete slabs, which turned a working water route into something closer to a clogged pipe you cannot properly clean. (indianexpress.com) The covered part is about 400 metres long, and officials say that stretch became a bottleneck because decades of silt built up underneath the slabs. When heavy rain hit central Delhi, water had less room to move through that narrow, choked section. (ndtv.com) By April 11, 2026, desilting on the Delhi Gate drain had crossed 70%, and more than 21,000 metric tonnes of silt had already been removed. Officials said the work is meant to restore the drain’s carrying capacity before the rains arrive. (timesofindia.indiatimes.com) The places expected to benefit are not random neighborhoods. Reports name ITO, Feroz Shah Road, the Supreme Court periphery, Daryaganj, Kashmere Gate, Chandni Chowk, Rajghat, and Mathura Road, which are all tied into the same central-Delhi drainage network and often snarl when water backs up. (hindustantimes.com) That matters in Delhi because monsoon flooding here is often less about one dramatic river event and more about short, intense rain hitting roads faster than drains can clear them. A blocked drain works like a sink with a half-shut outlet: the street fills first, and only then does the water start moving. (ndtv.com) The urgency also comes from recent memory. During the July 2023 flood crisis, the Yamuna reached 208.66 metres, and parts of Delhi including ITO, the Supreme Court area, Kashmere Gate, Civil Lines, and Mayur Vihar saw major disruption. (timesofindia.indiatimes.com) This drain project sits inside a much bigger pre-monsoon push. The Delhi government said it had already removed 14 lakh metric tonnes of silt from city drains and set a 2026 target of 28 lakh metric tonnes. (devdiscourse.com) The courts have been watching too. In December 2025, the National Green Tribunal ordered Delhi agencies to speed up drain desilting before the 2026 monsoon, and in early April 2026 it was told that work on the Irrigation and Flood Control department’s 77 drains was only 30.4% complete as of April 1. (downtoearth.org.in) (timesofindia.indiatimes.com) So the Delhi Gate drain is a small-looking fix with a very specific job: remove one old choke point so rainwater can get through the old city faster. If that 400-metre stretch stays open and clear through the monsoon, the change people notice first may be simple: fewer stranded buses, fewer ankle-deep crossings, and fewer hours when central Delhi stops moving.
