International Conference on Dam Safety Organised by Ministry of Jal Shakti Concludes at RIC, Jaipur

The International Conference on Dam Safety (ICDS) organised by the Department of Water Resources, River Development & Ganga Rejuvenation, Ministry of Jal Shakti has concluded at Rajasthan International Centre (RIC) in Jaipur. The closing session of the conference was chaired by the Union Minister of Jal Shakti, Shri Gajendra Singh Shekhawat. Addressing the august gathering, the Union Minister laid emphasis on the issue of dam health and safety which is likely to be a significant feature of the dam management in future. The Union Minister thanked all the participants and expressed confidence that the outcomes of the ICDS 2023 would go a long way for ensuring Dam safety and longevity of the critical dam infrastructure.

The Union Minister for Jal Shakti suggested key actionable points including setting up of a joint action force to take forward the Emergency Action Plans (EAPs) for dams with National Institute of Disaster Management (NIDM); creation of a compendium after analysis of the lacunae that have emerged during construction design as per the Dam Safety Reviews; chalking out a complete strategy integrating the deliberations and outcomes of the conference for its implementation. The Union Minister also recommended organising workshop to discuss the various dam Safety incidents and failures and its outcomes should be disseminated to all the dam owning agencies and other concerned stakeholders to avoid recurrence of such incidents.

Various technical sessions were organised during the two-day conference to enable foremost experts and leaders in the field to strengthen capacities for enhancing dam safety. Joint Secretary, DoWR, RD & GR, Shri Anand Mohan summarized the outcomes of the conference and shared the recommendations that emerged from the sessions during the 2-day conference.

Various presentations were made during the plenary session starting with the sharing of Government of India Initiatives on Dam Safety and Management, followed by other presentations covering the topics of the Dam Safety Status of Maharashtra; Regulating Dam Safety within the Australian State of New South Wales (NSW) sharing valuable experiences from Australia; Collaboration between Denmark & India on Water Management elaborating on the various collaboration efforts between the two nations; Collaboration between Australia & India on Water Management highlighting bilateral cooperation in water management; and World Bank Initiatives on Dam Management providing insights into the World Bank’s initiatives in the field.
