Cost and time overruns in India's major river valley projects: causes and lessons from the Sardar Sarovar Project.

Q. Cost and time overruns in India's major river valley projects: causes and lessons from the Sardar Sarovar Project. (15 marks, 250-350 words)

The Sardar Sarovar Project (SSP) began on 24 April 1987 at an approved cost of Rs 6,406.04 crore (1986-87 prices) [2], but eventually absorbed nearly Rs 44,000 crore on construction plus about Rs 16,000 crore in bond and interest payments [2] — an escalation that typifies why India's multipurpose river valley projects slip on both budget and schedule.

Causes of cost and time overruns - Litigation and clearance cycles: environmental clearance came only in June 1987, work was halted in 1994 on a Narmada Bachao Andolan petition, and resumed only after the Supreme Court's order of 18 October 2000 [3] — a lost decade that alone multiplied costs. - Inter-State cost-sharing disputes: the Narmada Water Disputes Tribunal Award (1979) bound four States, yet pending payment liabilities among Maharashtra, Gujarat, Rajasthan and Madhya Pradesh stayed unresolved for decades, settled only through a Centre-facilitated agreement in 2026 [1]. - Rehabilitation burden: roughly 40,727 families faced submergence — 33,014 in Madhya Pradesh alone [2] — making pari-passu R&R a recurring stoppage point. - Mid-course design revision: dam height was raised from 121.92 m to 138.72 m only after Narmada Control Authority approval in June 2014 [3], stretching completion. - Carrying cost of delay: bond servicing converted time overrun directly into financial overrun [2].

Lessons for project planning - Front-load clearances and R&R before ground-breaking, rather than litigating them mid-construction. - Institutionalise financial settlement mechanisms within basin authorities like the NCA, so cost-sharing dues do not accumulate into disputes [1]. - Strengthen dispute resolution — the single standing tribunal envisaged by the Inter-State River Water Disputes (Amendment) Act, 2019 addresses precisely the delay the NWDT experience exposed. - Adopt realistic, phased costing with periodic revised estimates instead of a single frozen figure.

Overruns are therefore governance failures more than engineering ones. Treating clearances, rehabilitation and inter-State finance as design inputs rather than afterthoughts — as the 2026 Narmada settlement finally demonstrates — can make cooperative federalism a project-delivery asset.
