Kerala demands comprehensive technical study of Mullaperiyar dam safety

Kerala has escalated its push for a thorough technical examination of the Mullaperiyar dam, submitting formal documentation to support its position ahead of safety panel discussions. The state government presented an eight-page written submission detailing specific safety concerns related to the century-old structure, which straddles the Kerala-Tamil Nadu border.

The comprehensive document outlines Kerala's rationale for requiring an independent and detailed technical study before any matters are presented to the designated safety committee. The submission reflects Kerala's long-standing concerns about the dam's structural integrity and its impact on communities downstream in Kerala.

The Mullaperiyar dam, constructed in 1895, has been a contentious issue between Kerala and Tamil Nadu for decades. While Tamil Nadu operates the dam for irrigation and power generation, Kerala has consistently raised concerns about its safety, particularly given its age and seismic vulnerability in the region.

The state's formal submission is expected to strengthen Kerala's negotiating position in ongoing discussions with Tamil Nadu and relevant central authorities. The documentation is likely to be reviewed before the safety panel convenes to discuss the dam's operational status and any required safety measures or modifications.
