Sector V Waterlogging: Kolkata’s IT and business hub, Sector V, witnessed severe disruption after heavy overnight rainfall left large parts of Salt Lake, New Town, and adjoining neighborhoods submerged under knee-deep water. The flooding reduced physical office attendance in Sector V to nearly 30%, forcing many firms to fall back on remote and hybrid work models.
While Kolkata is no stranger to monsoon waterlogging, this incident highlighted both the fragility of infrastructure in one of the city’s most modern districts and the growing challenge of maintaining business continuity during extreme weather.
Sector V Turns into a Waterlogged Island
The downpour inundated inner lanes and arterial roads of Sector V, cutting off access to buses, autos, and taxis. Commuters attempting to reach office buildings waded through murky floodwaters, while others were stranded at home.
In Salt Lake’s GD Block, water rose high enough to enter basements and staircases. Underground reservoirs and car parks were also submerged, leaving residents worried about property damage and electrical hazards.
For the IT workforce, which heavily depends on shared transport and daily commuting, the flooding translated into a dramatic fall in physical attendance. Only about one-third of employees managed to make it to their offices, while the rest either logged in from home or were unable to work at all.
Attendance and Productivity
The Nabadiganta Industrial Township Authority (NDITA) confirmed that physical attendance in most IT firms was far below average. Many companies activated their work-from-home fallback plans, ensuring that core operations continued even though on-site activity was limited.
“Attendance was barely 30% in some offices, but remote access tools helped prevent a complete shutdown,” said one industry association representative.
Still, productivity losses were unavoidable, particularly for roles requiring physical presence such as hardware maintenance, server room access, and facility management. Critical meetings and deadlines had to be rescheduled, while client-facing operations slowed down.
Why Did Sector V Flood So Severely?
1. Drainage Line Damage from Metro Work
Authorities revealed that a major drainage line near Technopolis, AL-BL Block Crossing, and the Wipro campus had been damaged during ongoing metro construction. This damage restricted the free flow of stormwater, creating bottlenecks that worsened waterlogging.
2. Pumping Capacity Limits
Though NDITA operated all five pumping stations at full capacity, and deployed portable pumps in low-lying areas, the sheer volume of water made quick clearance impossible.
3. Choked Manholes and Blocked Drains
The Bidhannagar Municipal Corporation (BMC) noted that silt, garbage, and incomplete desilting operations hampered stormwater discharge. Residents also reported that many drains overflowed within minutes of the rain.
4. Urban Density and Basement Vulnerability
With more high-rise IT towers and residential complexes in Sector V than ever before, the natural capacity for water absorption has reduced. Basements and underground utilities are especially vulnerable during floods.
Sector V Waterlogging: Official and Civic Response
- NDITA ran emergency pumping operations and coordinated with engineers to assess the damaged drainage line.
🔗 NDITA Official Portal - Bidhannagar Municipal Corporation sent teams to clear clogged manholes and mobilized relief pumps to the hardest-hit neighborhoods.
🔗 BMC Official Website - New Town Kolkata Development Authority (NKDA) used its integrated command-and-control centre to track water levels in real time and deploy disaster management units.
🔗 NKDA Official Website - West Bengal Government also monitored the crisis, linking it to larger infrastructure and urban planning challenges.

Broader Impact on Residents
Damage to Property
Vehicles in underground garages were submerged. In several housing complexes, electrical panels were flooded, forcing precautionary power cuts.
Health and Safety Concerns
Standing water increased risks of mosquito breeding, waterborne diseases, and electrical short circuits. Many residents expressed fear of venturing outside due to sanitation hazards.
Social Disruption
Daily essentials — groceries, medicines, and transport — became difficult to access. Schools and daycare centres were disrupted, affecting families with children.
Sector V as a Microcosm of Kolkata’s Waterlogging Crisis
This incident in Sector V is not isolated. Across Kolkata, waterlogging has become a chronic urban problem during heavy rains. Other areas such as Garia, Kalikapur, and Netaji Nagar reported even deeper flooding.
The India Meteorological Department (IMD) has warned that extreme rainfall events are likely to become more frequent with climate change.

Urban planners warn that unless Kolkata integrates climate resilience into infrastructure projects, high-density business districts like Sector V will face repeated disruptions.
Lessons and Way Forward
- Infrastructure Audits for Metro Projects
Future construction should mandate drainage impact assessments before work begins. Temporary diversions must be built for stormwater flows. - Enhanced Pumping and Drainage Capacity
Additional high-capacity pumps and secondary drainage networks are required in flood-prone zones. - Hybrid Work Preparedness
IT companies should strengthen remote working infrastructure, ensuring productivity is less vulnerable to physical disruption. - Citizen-Government Coordination
Residents’ associations can report blocked drains or damaged manholes through civic portals, enabling quicker action. - Climate-Resilient Urban Planning
Kolkata’s planning authorities must integrate green cover, permeable surfaces, and rainwater harvesting into urban design to reduce waterlogging.
Conclusion
The Sector V waterlogging attendance crisis is a reminder that modern business districts are not immune to basic urban failures. Despite gleaming IT towers and global firms, the district was paralysed by one night of heavy rain.
While hybrid work saved productivity, the flooding underscored how urgently Kolkata needs upgraded drainage systems, coordinated infrastructure planning, and climate-resilient design.
For now, Sector V employees may adapt with remote work, but long-term resilience will depend on whether civic authorities and businesses can work together to ensure that the next downpour doesn’t wash away Kolkata’s IT hub’s productivity.
