Kolkata Waterlogging Preparedness: As the festive season approaches with the promise of vibrant Durga Puja celebrations, the Kolkata Municipal Corporation (KMC) is stepping up its preparedness to combat one of the city’s most persistent challenges — urban waterlogging. With heavy rainfall predicted during the festival days, civic authorities are deploying pumping stations, portable pumps, and emergency response teams across vulnerable zones to ensure smooth mobility for millions of residents and pandal-hoppers.
KMC’s Drainage and Pumping Strategy
The civic body has directed that all drainage pumps remain on high alert, with leaves of staff suspended until further notice. Control rooms at KMC headquarters will monitor rainfall patterns, pump efficiency, and real-time reports from borough offices.
Key steps include:
- All 35 pumping stations kept operational with dedicated teams.
- Over 500 portable pumps deployed in low-lying and “added areas” like Behala, Garden Reach, Garia, and EM Bypass.
- Jetting-cum-suction machines on standby to clear clogged drains and gully pits.
- Manual cleaning gangs stationed in each borough for swift removal of blockages.
- Emergency task force assigned to sensitive areas where drainage upgrade work is ongoing.
These measures aim to avoid a repeat of past monsoon troubles, where heavy rain coinciding with high tide led to severe flooding in multiple neighborhoods.

Waterlogging and the Challenge of Plastic Waste
One of the biggest obstacles in Kolkata’s drainage system is plastic pollution. Despite repeated awareness campaigns and bans, thin plastic bags and non-biodegradable waste continue to clog drains, particularly in busy markets and residential localities.
Every monsoon, KMC workers find gully pits filled with discarded plastic and debris, which reduces pump efficiency and slows down stormwater discharge. In fact, civic engineers admit that even the most advanced pumps fail to function when inlets are blocked.
To address this, KMC has launched pre-puja gully pit cleaning drives, urging residents to avoid dumping waste irresponsibly. Officials have reiterated that citizen cooperation is crucial in keeping drains functional during the festival.

High Tide, Sluice Gates, and Flood Risks
Kolkata’s geography adds another layer of complexity. The city’s drainage system depends on gravity-based flow into the Hooghly River. However, when the river is at high tide, KMC has to close sluice gates to prevent backflow. This temporarily traps stormwater within the city and causes waterlogging even in areas with adequate pumps.
To mitigate this, KMC is using synchronized pumping schedules and exploring modern sluice gate automation. Civic engineers are also monitoring tide charts from the Indian National Centre for Ocean Information Services (INCOIS) to coordinate pumping more effectively.

Kolkata Waterlogging Preparedness: Festival-Specific Preparedness
Durga Puja, declared by UNESCO as an Intangible Cultural Heritage of Humanity, brings lakhs of visitors to Kolkata every year. The risk of waterlogging not only disrupts pandal visits but also raises safety concerns such as electrocution from submerged wires.
To address this, KMC is:
- Deploying portable pumps near major pandals to drain water immediately.
- Setting up dedicated emergency response teams in collaboration with the Disaster Management Department.
- Inspecting temporary electrical connections near pandals to avoid accidents.
- Coordinating with Kolkata Police for traffic management in waterlogged zones.

Broader Urban Resilience Measures
Experts believe that Kolkata’s recurring waterlogging problems point to a need for long-term resilience strategies. Short-term pump deployment offers relief but does not solve systemic issues like:
- Outdated colonial-era drainage systems.
- Encroachment on canals and wetlands that once absorbed excess water.
- Lack of sustainable urban planning in newly developed areas.
- Rising rainfall intensity due to climate change.
Urban planners argue for canal desilting, wetland preservation, and smart water management as permanent solutions. Integration of IoT-based flood sensors, already in use in cities like Singapore and Dhaka, could also be a game-changer for Kolkata.

Community Role in Reducing Waterlogging
While KMC bears the responsibility of drainage, residents too play a critical role. Civic officials have appealed to households, businesses, and puja committees to:
- Avoid littering and dumping waste into drains.
- Report clogged gully pits to borough offices.
- Cooperate with KMC teams during pumping and cleaning operations.
- Use eco-friendly materials in pandal decoration and immersion.
Community-driven clean-up campaigns and awareness drives are being planned in collaboration with NGOs and schools.
Conclusion
The Kolkata Municipal Corporation’s preparedness against waterlogging reflects both the urgency of the moment and the recurring challenge of monsoon-induced flooding. By keeping pumps, portable units, and emergency teams on standby, the city hopes to ensure a smooth and safe Durga Puja for residents and visitors.
However, experts warn that true resilience lies in long-term reforms — modernizing drainage systems, tackling plastic waste, and integrating climate-smart planning into urban development. Until then, every monsoon and every Puja season will remain a test of Kolkata’s endurance and civic coordination.
