Polavaram Project

The Polavaram Project is a multipurpose river-valley scheme on the lower Godavari River at Polavaram village in the Eluru district of Andhra Pradesh, conceived to provide irrigation, hydroelectric power, and drinking water across the state's coastal delta. Its modern legal foundation rests in the Andhra Pradesh Reorganisation Act, 2014, which under Section 90 declared Polavaram a national project and authorised the Union Government to execute and fund the irrigation component. The same provision deemed all environmental, forest, and inter-state clearances for the project to have been conveyed, a legislative shortcut intended to insulate the scheme from the procedural delays that had stalled it since the 1940s, when the Khosla Committee first surveyed a barrage near Ramapadasagar. The project was formally renamed the Indira Sagar Polavaram Project and its full reservoir level fixed at 45.72 metres (150 feet).

Procedurally, the project advances through a sequence of statutory and engineering gateways. The Central Water Commission appraises the detailed project report and reviews dam-safety and hydrological design; the Ministry of Environment, Forest and Climate Change issues the environmental clearance, originally granted in 2005; and forest clearance follows under the Forest (Conservation) Act, 1980, given the submergence of forest land. Inter-state concurrence derives from the Godavari Water Disputes Tribunal Award of 1980, which permitted Andhra Pradesh to construct a dam at Polavaram subject to protective conditions for the upstream states of Madhya Pradesh (now Chhattisgarh) and Odisha. The physical works comprise an earth-cum-rockfill main dam, a spillway designed for one of the highest flood-discharge capacities in the world, a hydroelectric station of approximately 960 megawatts installed capacity, and left and right main canals that interconnect the Godavari with the Krishna basin.

A defining feature is the project's inter-basin transfer function. By diverting up to 80 thousand million cubic feet (TMC) of Godavari water to the Krishna River above Vijayawada, the scheme triggers a water-sharing entitlement among the upstream Krishna-basin states under the 1980 award, allowing Maharashtra, Karnataka, and Telangana to draw additional Krishna water in compensation. The project is engineered to irrigate roughly 2.91 lakh hectares (about 7.2 lakh acres), supply drinking water to villages along the canal alignment, and stabilise existing delta ayacut in the Godavari command. Funding mechanics shifted after 2014: the Union committed to reimburse the irrigation component, with the National Bank for Agriculture and Rural Development routing funds and the Polavaram Project Authority, constituted by the Centre in 2014, overseeing execution alongside the Andhra Pradesh Water Resources Department.

In contemporary practice the project has been a recurring item in fiscal negotiations between Amaravati and New Delhi. The Andhra Pradesh government, under successive administrations led by Chandrababu Naidu and Y. S. Jagan Mohan Reddy, repeatedly pressed the Ministry of Jal Shakti and the Polavaram Project Authority over reimbursement of expenditure and revised cost estimates, which escalated past ₹55,000 crore. Diaphragm-wall damage discovered after floods in 2022 forced the Central Water Commission and a panel of dam-safety experts to recommend remedial construction, delaying the targeted completion repeatedly across the 2020s. The Ministry of Tribal Affairs and the National Commission for Scheduled Tribes have scrutinised the rehabilitation of displaced Koya and Konda Reddi communities in the submergence zone.

The Polavaram Project must be distinguished from adjacent instruments. It is not a river-linking scheme of the National Perspective Plan in the manner of the Ken-Betwa Link, though its Godavari-Krishna transfer is sometimes cited as a partial realisation of the Godavari-Krishna interlink. It differs from a barrage such as the older Sir Arthur Cotton (Dowleswaram) anicut, being a storage dam with a live reservoir rather than a low diversion weir. As a national project it occupies a distinct funding and oversight category from a state major-irrigation project, attracting Union financing and a dedicated central authority. It should also be separated from the Godavari Water Disputes Tribunal itself, which is the adjudicatory body whose 1980 award supplies the project's inter-state legal basis rather than the construction scheme.

The principal controversies concern submergence and federalism. The reservoir at full level inundates villages in Chhattisgarh and Odisha, both of which approached the Supreme Court contesting the deemed clearances and the absence of fresh consent, raising questions about whether Section 90 of the Reorganisation Act could override the consent architecture of inter-state river governance. Backwater-effect modelling, the adequacy of relief-and-rehabilitation packages for an estimated 1.06 lakh displaced families across nearly 370 villages, and the recurrence of submergence in flood years have kept the project before the National Green Tribunal and parliamentary committees. The discovery of seepage and the gap in the diaphragm wall after the 2022 floods reopened technical disputes over construction sequencing and quality assurance.

For the working practitioner—whether a UPSC aspirant addressing GS Paper 1 geography and GS Paper 2 federalism, a water-resources desk officer, or a journalist covering Andhra-Telangana relations—the Polavaram Project is a compact case study in how a single infrastructure asset binds together physical geography, tribunal law, centre-state finance, environmental clearance regimes, and tribal displacement. It illustrates the legislative device of deeming clearances, the politics of national-project status, and the durability of the 1980 tribunal award as a governing instrument. Mastery of its cost trajectory, statutory basis, and inter-state implications equips the analyst to interpret a recurring fixture of Indian federal and developmental debate.
