Polavaram Project: A Critical Analysis

Why in news?

The Biju Janata Dal (BJD) has recently intensified its efforts to highlight the potential adverse impacts of the Polavaram Dam project.

Introduction

• The Polavaram Project is a multi-purpose irrigation and hydroelectric project being constructed on the Godavari River in Andhra Pradesh.

• It has been granted National Project status by the Government of India.
• The project aims to benefit the water-scarce regions of Andhra Pradesh, Telangana, and other southern states.
• However, it has sparked controversy due to its interstate impact, particularly concerning water-sharing disputes and environmental concerns.

Project Overview

• Location: The Polavaram Dam is located in the Eluru and East Godavari districts of Andhra Pradesh, affecting the Sabari River side, which extends up to 115 km into Chhattisgarh and Odisha.
• National Project Status: The project has been designated as a National Project by the Central Government, signaling its importance for national development.
• Reservoir Impact: The reservoir will impact the Papikonda National Park, raising environmental concerns, particularly regarding biodiversity and wildlife conservation.
• Future Use: The project holds the potential for large-scale river linking initiatives such as Godavari-Penna and Godavari-Krishna river linking. This could prevent surplus water from flowing into the sea and help alleviate water shortages in deficit regions.

Interstate Water Disputes

• The Polavaram project has led to disputes between Andhra Pradesh, Telangana, Odisha, and Chhattisgarh over water sharing and submergence levels.
• The matter is currently under the scrutiny of the Supreme Court, which is addressing the concerns raised by these states.
• BJD’s Concerns: The Biju Janata Dal (BJD) of Odisha has raised several issues related to the project, notably:
  • Backwater Study: The Central Water Commission (CWC) has reportedly refused to conduct a backwater study despite the concerns of Odisha and expert recommendations. This has raised doubts about the potential flooding risks in Odisha, particularly for tribal populations living near the Godavari basin.
  • Submergence Levels: Different studies have presented varying flood submergence estimates. A 2009 report by Andhra Pradesh indicated that a 50-lakh cusec flood could cause submergence up to 216 feet in Odisha, which exceeds the originally agreed maximum level of 174.22 feet. A 2019 IIT Roorkee study projected an even higher submergence level of 232.28 feet in Odisha for a 58-lakh cusec flood.

Current Status

• Completion Timeline: Andhra Pradesh CM N. Chandrababu Naidu has set a target to complete the Polavaram project by 2027.
• Union Government Support: The central government has allocated ₹15,000 crore in the budget to expedite the completion of the project.
• Environmental and Safety Concerns: The BJD and other stakeholders continue to express concerns over the environmental impact, safety risks, and the adequacy of flood submergence studies.
• Ongoing Disputes: Water-sharing disagreements between the states remain unresolved, with the matter pending before the Supreme Court.

Conclusion

• The Polavaram Project is a crucial infrastructure initiative aimed at addressing water scarcity and boosting irrigation in the southern states of India.
• However, it faces significant opposition due to concerns about environmental degradation, interstate water disputes, and inadequate studies on flood submergence.
• It is essential for all concerned parties to engage in constructive dialogue, backed by scientific studies and legal processes, to ensure the project’s benefits outweigh its potential risks.
