Not just a dam — a multi-purpose mega system converting a 30 km stretch of the Arabian Sea into the world's largest freshwater reservoir, with a 10-lane highway on top, solving Gujarat's water future forever.
Massive volume of freshwater currently flowing into the sea will be stored — sourced from rivers across Gujarat.
A full 10-lane expressway built directly on top of the sea dam — dramatically cutting distances across Gujarat.
One of the costliest infrastructure projects in India — cost estimates have scaled with project scope and inflation over decades of planning.
This is a long-term mega project — completion realistically expected between 2035–2040 after DPR approval.
Without water, Dholera cannot scale — Kalpsar solves that.
Kalpsar is not just a dam — it is a multi-purpose mega system combining water security, road connectivity, land reclamation, and economic transformation into a single engineering marvel. If executed properly, it will completely change Gujarat's water future and make Dholera Smart City fully sustainable — potentially becoming the world's largest freshwater reservoir built in the sea.
