Heavy rain on July 28 sent floodwater into homes, shops, schools and colleges across Nagpur, forcing rescue teams to evacuate children from waterlogged buildings. Residents and planners now point to an unlikely culprit: the city’s own cement road program. Newly laid concrete roads have been built at levels higher than the stormwater drains beside them, according to Nagpur Today, turning the roads themselves into barriers that trap rainwater instead of channelling it away.

A drainage problem built on purpose

The Nagpur Municipal Corporation (NMC) has spent roughly Rs 1,047 crore across four phases of cement road construction covering more than 150 roads, per The Hitavada. Concrete resurfacing typically raises a road’s height once new layers are laid over the old surface. That routine engineering step, done without corresponding drain upgrades, leaves roads sitting above the channels meant to carry rainwater off them. Sujit Rodge, an architect-planner and former chairman of the ITPI Maharashtra Regional Chapter in Nagpur, told The Hitavada that raised concrete surfaces “act as artificial barriers, trapping rainwater instead of channeling it into drainage networks,” and that responsibility lies less with contractors than with the engineers who designed the projects without anticipating this outcome.

Both outlets report that NMC’s zonal engineers, the officials meant to sign off on individual road projects, did not ensure the works complied with drainage standards. Nagpur Today adds that drainage lines were, in several stretches, “narrowed, covered or blocked during construction,” compounding the level mismatch. Encroachments along existing drains, a long-standing enforcement gap in the city, have narrowed capacity further.

Not the first warning

Nagpur has been here before. The city’s catastrophic floods of September 23, 2023 prompted promises of better pre-monsoon desilting and drainage upgrades; NMC has budgeted roughly Rs 15 crore a year toward desilting since. That spending has not stopped this year’s repeat flooding, which suggests the bottleneck is less about clearing silt from existing drains and more about new infrastructure working against them. The Manish Nagar underpass flooded again in July despite a fresh disaster-management plan, a pattern of infrastructure outpacing the drainage it depends on.

What it means for residents

For households and shopkeepers along the affected stretches, the practical risk is that a well-funded road upgrade meant to improve daily commuting is instead funnelling rainwater directly into their properties during heavy spells, an outcome largely invisible until the next downpour. Areas near State PWD works in Civil Lines were also flagged for similar construction-level violations, indicating the problem isn’t confined to NMC’s own contractors. Insurance claims, repeated cleanup costs and disrupted school and business days are the tangible cost of a design gap that residents say could have been caught before construction, not after.

What to watch next

NMC is preparing a fifth phase of cement roads worth roughly Rs 900 crore, with the exact stretch of roads still to be finalised. Citizens’ groups are pushing for accountability and design corrections, matching road levels to drain capacity and keeping stormwater channels clear during construction, before that phase is approved. Whether NMC revises its design and sign-off process for Phase V, or repeats the same level mismatch at even greater scale, will determine if this monsoon’s flooding was a one-off or the start of a recurring pattern tied directly to the city’s own infrastructure spending.
