How Delhi Plans to Beat the Water Crisis: Haryana's Help, 980 Tankers and New Borewells Explained

Delhi’s severe heatwave and record temperatures have collided with a major water crisis, but a crucial relief plan is now in motion. The Delhi government reports that Haryana has agreed to increase water released through the Munak canal, while emergency tanker services and long-term projects aim to stabilise Delhi’s water supply over the coming weeks.

Falling levels in the Yamuna have sharply affected production at key water treatment plants. According to the Delhi Jal Board, the normal pond level at Wazirabad should stand at 674.5 feet, but it dropped to around 668 feet. This fall of nearly 6.5 feet led to a shortage of raw water and dragged total production around 90 MGD below the target of 1002 MGD, disrupting supply in many neighbourhoods.

Delhi water supply boost from Haryana through Munak canal

Chief Minister Smt. Rekha Gupta stated that Haryana has now promised to maintain a minimum daily release of 1000 cusec water to Delhi via the Munak canal. This assurance is higher than Delhi’s allocated quota of 924 cusec and follows a detailed review meeting with senior Delhi Jal Board officials and Water Minister Shri Parvesh Verma on 30 May 2026.

Before this intervention, Delhi had been receiving only about 900 to 924 cusec from the Munak canal. After direct talks between Chief Minister Rekha Gupta and Haryana Chief Minister Nayab Singh Saini, Haryana agreed to supply at least 100 additional cusec beyond the quota, taking the minimum flow to 1000 cusec every day. Officials say this added water will help restore output at affected water treatment plants.

Delhi is surrounded by land on all sides and does not have any large natural water source of its own. The city relies mainly on neighbouring Haryana and Uttar Pradesh for drinking water. This year’s heat has broken many past records, leading to prolonged dryness in the upper stretches of the Yamuna, which then cut inflows to Delhi’s plants and aggravated the already fragile Delhi water supply situation.

Delhi water supply emergency measures and tanker operations

Until the additional water from Haryana normalises flows through the full distribution network, the Delhi government has activated an emergency plan. More than 980 water tankers have been deployed across the city, making over 6000 trips each day. Smaller tankers are being used in congested lanes and high-density colonies so that local residents receive at least some relief despite the Delhi water supply shortfall.

To tap groundwater in the short term, new borewells have been drilled in the Yamuna floodplain area, also known as Yamuna Khadar. Officials report that these borewells have immediately added about 10.5 MGD to the system’s capacity. This extra volume is being routed to particularly stressed pockets, while engineers continue monitoring quality and pressure in affected zones.

Complaints about disrupted Delhi water supply have surged, and the Delhi Jal Board helpline has recorded 11055 water-related calls in the past week alone. According to officials, more than 8500 of these complaints have already been addressed. The Chief Minister has instructed officers to treat every pending case as urgent and has warned that wastage and leakages will not be tolerated under any circumstances.

Officers have been told to carry out surprise inspections in the field and verify that tankers reach their notified locations. They have also been asked to personally monitor complaint resolutions. Rekha Gupta told officials that “Delhi ke nagrikon ko is bhishan garmi mein pyasa nahi chhoda ja sakta aur sarkar har nagrik tak peene ka saaf paani pahunchane ke liye pratibaddh hai,” stressing the administration’s responsibility to keep drinking water flowing.

Delhi water supply long-term plans and IIT Roorkee study

Alongside emergency actions, the Delhi government is working on long-term safeguards for the Delhi water supply. A major concern is transmission loss when water travels through open channels like the Munak canal. Losses occur due to theft, leakage and evaporation before the water reaches Delhi. To address this, IIT Roorkee has been tasked with a scientific feasibility study.

IIT Roorkee’s team is examining whether a fully closed, dedicated pipeline system can be created from Haryana to Delhi. Such a pipeline would aim to reduce theft and seepage and protect supplies from heat-related evaporation. The study will look at technical designs, cost, pressure management and routing, and its findings are expected to shape future Delhi water supply infrastructure decisions.

Work is also planned at Wazirabad to improve storage at the pond that feeds several treatment plants. Authorities intend to start dredging and desilting near Wazirabad so that accumulated silt is removed. Increasing the pond’s capacity should help Delhi store more water during periods of better flow, and then release it gradually when the Yamuna’s level dips.

New water treatment plants are being set up to handle higher volumes and improve Delhi water supply reliability. Officials say these plants will help spread the load across the network and reduce pressure on ageing units. Upgraded systems are expected to manage variations in raw water availability more efficiently, especially during harsh summers.

Along with infrastructure changes, the government is pushing water conservation and rainwater harvesting across the city. In 75 'CM Shri’ schools in Delhi, rainwater harvesting systems are being developed to store rooftop run-off. Citywide, work has begun on constructing 500 new rainwater harvesting structures and reviving 1000 older ones that had fallen into disuse, with the tender process for these projects already under way.

Officials believe that increased releases from Haryana, combined with tankers, new borewells and network repairs, will gradually stabilise the Delhi water supply in coming days. At the same time, the planned pipeline study, desilting at Wazirabad, new treatment plants and expanded rainwater harvesting are intended to reduce the impact of future heatwaves and protect Delhi’s residents from similar large-scale water stress.
