Gurgaon Pitches Underground Wells and Tanks to Fight Flooding
Gurugram often floods when heavy rain falls very quickly.
The city wants to build underground wells and tanks to move rainwater away from roads.
The tanks would collect water, and the wells would send filtered water deeper underground.
Officials hope to install the system at four especially bad flooding locations first.
They want the system to handle three times the amount of rain expected during the heaviest storms.
A monitoring network would track how much water goes underground.
Some experts support the idea if it is properly designed, funded and monitored.
Other experts say the city must also clear blocked drains, protect ponds and reduce the effects of too much concrete.
They warn that underground technology alone may not solve the flooding problem.
Gurugram officials are proposing high-capacity rainwater injection wells and underground storage tanks to reduce waterlogging.
The first phase targets chronic flooding points at Subhash Chowk, Rajiv Chowk, the Medanta underpass and Sheetla Mata Road.
The wells are designed to absorb 48 to 80 litres per second, with tanks capturing runoff before groundwater recharge.
Officials want the system completed within a year, with capacity equal to three times expected peak rainfall and real-time SCADA monitoring.
Experts said the plans must be paired with drain clearance, ecological restoration, better budgeting and controls on concretisation.
- Who
- The Haryana government, the Municipal Corporation of Gurugram, the Gurugram Metropolitan Development Authority, IIT Gandhinagar experts and environmental specialists.
- What
- A plan to use high-capacity rainwater injection wells and underground storage reservoirs to reduce waterlogging and recharge groundwater.
- When
- The proposals were discussed with the prime minister on Thursday; technical reviews took place Tuesday and site inspections Wednesday. Officials want the first installations completed within one year and 100 rainwater-harvesting structures ready before the next monsoon.
- Where
- The first phase focuses on Subhash Chowk, Rajiv Chowk, the Medanta underpass and Sheetla Mata Road, with inspections also conducted in Sectors 46 and 47 of Gurugram.
- Why
- Gurugram experienced intense rainfall and has recurring waterlogging linked by officials and experts to rapid runoff, drainage constraints, concretisation and blocked natural water flows.

Can wells and tanks reduce flooding?
Underground technology advocates
Officials say high-capacity wells and storage tanks can quickly capture road runoff, bypass waterlogged upper ground and recharge deeper aquifers.
Infrastructure and ecology skeptics
Critics say such systems often fail when poorly designed and cannot compensate for blocked drains, inadequate implementation and excessive concretisation.
What should be prioritised?
Underground technology advocates
The government is prioritising engineered interventions, real-time SCADA monitoring and large drainage projects, alongside recharge wells and rainwater-harvesting structures.
Infrastructure and ecology skeptics
Experts argue that the city also needs ponds and reservoirs in parks, removal of drain encroachments, ecological restoration and stronger budgeting and oversight.
Understanding the source of flooding
Underground technology advocates
Officials point to unusually heavy rainfall and are pursuing measures such as check dams, revitalised ponds and routes to move runoff through Nuh toward the Yamuna basin.
Infrastructure and ecology skeptics
Sustainability expert Sunil Pachar attributes the problem more fundamentally to increased concretisation and obstruction of the natural slope from the Aravallis toward Najafgarh, while calling for local input.
- Proposed technologies
- High-capacity rainwater injection wells paired with underground storage tanks.
- Well absorption rate
- Approximately 48 to 80 litres per second.
- Target completion
- Officials called for installations to be completed within one year.
- Design capacity
- The combined tanks and wells are to handle three times the expected peak-rainfall volume.
- Rainfall reported
- Gurgaon received 230 millimetres of rain between August 6 and 8 and had the second-highest seasonal rainfall in Haryana after Yamunanagar.
- Existing waterlogging response
- The government said it has targeted 99 waterlogging points and installed recharge wells that injected about 13,000 metric litres of storm runoff.
- Additional rainwater project
- An IIT Delhi project is intended to create 100 structures that could channel 25 to 30 crore litres into the water table before the next monsoon.
