The Delhi Jal Board (DJB) has issued an official water supply disruption alert, confirming that a critical pipeline connected to the Haiderpur Water Treatment Plant (WTP) has been damaged and requires urgent emergency repair work. Until that repair is completed, the water simply will not flow.

If you live in any of the 12 affected colonies, here’s everything you need to know — the exact timings, the full list of impacted areas, and the emergency numbers you should save right now.

The Exact Timing — Mark This Carefully

This isn’t a vague “water may be disrupted” kind of notice. DJB has given precise timings, and residents need to plan accordingly:

• Water supply cut starts: March 17, 2026 at 10:00 AM
• Water supply resumes: March 18, 2026 at 10:00 AM
• Total duration of disruption: 24 hours
• Reason: Emergency repair work on the main pipeline originating from Haiderpur WTP
• Cause of damage: The primary water main connected to Haiderpur WTP has been found to be structurally damaged and requires immediate attention

Once the repair work is fully completed, normal water supply will be restored. DJB has stated that this is a temporary disruption and not a prolonged water crisis.

Full List of Affected Colonies — Check Your Area

Three assembly constituencies are impacted across a combined total of 12 colonies. Here’s the complete breakdown:

Rohini Assembly Constituency (AC-13)

• Sector 15, Rohini
• Sector 18, Rohini
• Sector 19, Rohini
• Badli Industrial Area (Phase 1, Phase 2, and Phase 3)
• Suraj Park
• Raja Vihar
• Prashant Vihar
• Surrounding areas of Prashant Vihar

Rithala Assembly Constituency (AC-06)

• Sector 16, Rithala
• Sector 17, Rithala
• Sardar Colony
• Amar Jyoti Colony
• Surrounding localities

Badli Assembly Constituency (AC-05)

• Samaypur
• Shivpuri
• Teacher Colony
• Badli Village
• Surrounding areas

If your colony or sector falls within any of these three assembly areas — even if not explicitly named above — it’s worth calling the helpline numbers below to confirm whether your area will be impacted.

Emergency Numbers — Save These Before Anything Else

DJB has released specific contact numbers for residents who need water tankers during the 24-hour disruption period. Don’t wait until you’re out of water to make these calls — contact them early so a tanker can be scheduled in advance:

For Rohini (AC-06 and AC-13):

• 8770530657
• 9289138498

For Badli (Park area specifically):

• 9654708881 — JE Shri Samrat

General Water Emergency Numbers (applicable across affected areas):

• 9024780000
• 9650755709
• 8178020816
• 9650094327
• 9643575478

DJB’s 24-Hour Central Emergency Helpline:

• 1916 — This is the number to call for any water-related emergency across Delhi, regardless of your area

Save all these numbers right now. Once the disruption begins at 10 AM on March 17, demand for tankers will be high — the earlier you book, the better your chances of getting water delivered without a long wait.

What You Should Do Right Now — A Quick Checklist

If you live in any of the areas listed above, here’s what practical preparation looks like before 10 AM today:

• Fill every large container, bucket, and drum you have — drinking water, cooking water, and bathroom water separately
• Fill your overhead tank or storage tank completely if you have access to do so
• Save the emergency tanker numbers listed above in your phone right now
• Inform your household help, cook, or anyone else in your home about the disruption so they can plan accordingly
• Book a tanker in advance if you know your storage won’t be enough for 24 hours
• Keep the DJB helpline 1916 handy for any escalation or update

One thing worth knowing — tanker requests tend to pile up heavily once a disruption begins. If you call at 2 PM after your water runs out, you may be waiting several hours for a delivery. Early preparation genuinely makes a difference here.

Why the Haiderpur WTP Disruption Is a Big Deal

To understand why 12 colonies across three assembly constituencies are affected by one pipeline fault, it helps to know what the Haiderpur Water Treatment Plant does.

Haiderpur WTP is one of Delhi’s largest and oldest water treatment facilities. It processes and supplies treated water to a significant portion of North and North-West Delhi, feeding areas like Rohini, Rithala, Badli, and several adjoining localities through a network of major distribution pipelines. When the main trunk line coming out of this plant is damaged, there’s simply no alternative route to push water to these areas — the supply stops entirely until the line is fixed.

DJB has confirmed that the repair team is treating this as an emergency job, which means it’s being prioritised. The 24-hour window given is the estimated time for the repair to be completed. In most cases like this, supply is restored close to the announced time — but having a water reserve ready is always the smarter approach.

A Note for Housing Societies and RWAs

If you’re a Resident Welfare Association (RWA) member or a housing society manager in any of the affected sectors, this is the time to:

• Send an immediate circular to all residents about the disruption timings
• Arrange for a common water tanker for the society if individual storage is insufficient
• Contact the JE number for Badli or Rohini as applicable and book a tanker in advance for the entire society
• Ensure the society’s sump or underground reservoir is fully filled before 10 AM today

A coordinated response at the society level will prevent individual panic and ensure that elderly residents and families with young children aren’t left without water during the 24-hour window.

The Bigger Picture — Delhi’s Water Infrastructure Challenge

This disruption, while temporary and being addressed, is also a small window into a larger challenge Delhi has been grappling with for decades. The city’s water distribution network — much of which was laid decades ago — is ageing. Pipe bursts, leakages, and emergency repair shutdowns are not unusual, particularly in older colonies and industrial areas that haven’t seen significant infrastructure upgrade in years.

The Delhi government has recently announced a 9-zone master plan to overhaul water distribution across the capital, with the goal of reducing such emergency disruptions over time. That’s a welcome development — but for residents dealing with a dry tap today, the long-term plan offers cold comfort. What they need right now is a filled bucket, a working tanker number, and clear information.

DJB has, to its credit, given residents a full day’s advance notice and released specific helpline numbers for tanker requests — which is more organised than many past disruptions have been.
