Sitharaman highlights Puducherry kulam restoration for water security
Synopsis
Key Takeaways
Union Finance Minister Nirmala Sitharaman on Friday, 26 June 2026, shared details of the restoration of Muzhiyan Kulam, a traditional two-acre pond in Puducherry, highlighting its role in reviving the region's heritage water infrastructure and bolstering water security along the coast.
Context
The Muzhiyan Kulam, also known as Naangu Mozhi Kulam, is a historic water body spread across 2 acres in Puducherry. The restoration involved desilting the pond, restoring its original bed contours and embankments, and removing encroachments that had accumulated over the years. A boundary wall and a walking track were constructed, and public facilities were added to the site.
A rainwater management system inspired by the ancient Naangu Mozhi design — originally featuring four Mozhi wells connected through underground chambers — was implemented as part of the project. The restored kulam is reported to now store nearly 5 crore litres of water, recharge groundwater, and act as a barrier against seawater intrusion into the coastal territory.
Policy Backdrop
The restoration reflects a broader national push to revive pre-modern tank and kulam systems across southern coastal regions. The central government's Mission Amrit Sarovar, launched in April 2022, set a target of rejuvenating at least 75 ponds per district nationwide, with emphasis on desilting, encroachment removal, and the revival of traditional water harvesting structures.
Puducherry, as a coastal Union Territory, faces acute groundwater depletion and seawater intrusion — challenges that make the revival of heritage water bodies particularly urgent. The kulam project integrates ancient engineering principles with contemporary water management needs, aligning with frameworks under Jal Shakti and the National Water Mission.
Stakeholders and Impact
Residents of Puducherry and local groundwater users stand to benefit directly from the restored kulam's recharge function. The site's capacity to store significant volumes of rainwater and slow seawater ingress addresses a pressing ecological concern for a territory with limited freshwater reserves.
Beyond utility, the restoration preserves a piece of Puducherry's architectural and hydrological heritage. The Naangu Mozhi design, with its network of interconnected underground chambers, represents an indigenous engineering tradition that predates modern water infrastructure by centuries.
What's Next
Attention will now turn to whether Puducherry expands its kulam restoration programme to additional water bodies under a broader water security plan. Post-monsoon groundwater monitoring data for the Muzhiyan Kulam site will be a key indicator of the project's long-term effectiveness. The success of this model could inform similar interventions in other coastal Union Territories and districts facing comparable groundwater stress.
