Vivekananda Seva Samithi (VIKASA) Karimnagar Hyderabad Alternative Proposal for Polavaram Project WIN – WIN SOLUTION for all stakeholders M Dharma Rao Chief Engineer (Retd) December, 2010
VIKASA • Polavaram (Indira Sagar) Multi-Purpose Project • …a brief background
Key features of Polavaram Project Cotton Barrage VIKASA
Key features of Polavaram Project…(contd.) VIKASA • A dam across R. Godavari near Polavaram Vill. (WG Dist.) • Would create 75.2 TMC Reservoir • Irrigation for 7.2 lakh acres (projected) • Left flank : irrigation + drinking water en route to Visakhapatnam (25 TMC) & ors • Right flank : irrigation - diversion of 80 TMC to Krishna Barrage (linking of Krishna & Godavari Rivers) • Downstream : supplementing Godavari delta in case of shortfall • Hydropower generation capacity 960 MW (= 12 x 80 MW)
VIKASA II. Polavaram Project suffering from several key deficiencies
Deficiencies of Polavaram Project VIKASA • Current status: full project clearances not yet obtained! Main dam and storage structures not yet constructed. • Submergence & environmental degradation: 2 lakh acres (1.5 lakh acres farm land & 0.5 lakh acres forest land); massive loss of rare flora & fauna; major loss to Papikonda Wildlife Sanctuary (Tiger habitat); loss of heritage and sacred structures • Relocation and ‘forced impoverishment’ a snowballing issue: more than 2 lakh people (65% tribals & dalits) in over 300 villages; forced to migrate and lose assured livelihoods • High and rising project cost estimates – a serious concern: capital (Rs. 16,000 crores and counting!) and recurring (due to lift component); sanctions withheld on financial grounds • Inter-regional disputes (“Telangana vs. Coastal Andhra”) • Inter-state disputes (Chattisgarh, Orissa vs. AP) – recent MoEF notices; CWC’s approval after OK by other States under GWDT
Deficiencies of Polavaram Project (contd.) VIKASA • Violating Draft National Tribal Policy: mandatory principle of least displacement; any project which displaces more than 50,000 tribal people would not be taken up or be subject to more stringent norms • Violating Environment Protection Act (1986) & EIA Notifications (1994, 1997 & 2004) : • - project should not deprive livelihoods of poor and tribal people • - mandatory to find out alternatives…to protect the environment • Against National Water Policy: does not permit state-induced impoverishment due to forced displacement, acquisition of lands • Against recommendations of Prof. Jayati Ghosh Commission, National and State Resettlement and Rehabilitation Policy (2003 & 2005), etc.
Deficiencies of Polavaram Project (contd.) VIKASA • Outdated Model of Development? Priorities seen to be skewed • project’s primary beneficiaries (relatively better-developed plain and delta) vs. primary losers (underdeveloped tribals and dalits in more backward regions) • Supreme Court’s Central Empowered Committee (CEC) on Polavaram: • submergence of villages and forced displacement of large populations • irreparable loss of invaluable wildlife zones & tiger habitat • ‘a fresh appraisal’ & ‘a second thought required before sanctioning project’ • ‘a strong case for exploring alternative location and design’ • Ref: CEC’s Report dated 9-11-2006 (vide F. No. 1-19/CEC/SCA/2006 – PT XII dated 15-11-2006) in I.A. No. 1572 and 1578 in the Supreme Court of India
Deficiencies of Polavaram Project (contd.) VIKASA • Actual gains much lower than claimed ! Duplication of Polavaram Ayacut: • Claimed area – 7.2 lakh acres • But, 5.2 lakh acres of this area shown as covered under other projects: Yeleru, Torigedda LIS, Chagalnadu LIS, Tadipudi LIS, Pushkaram LIS! • Tadipudi and Pushkaram LIS alone cover 3.92 lakh acres of same area ! • Polavaram ayacut to be much lower
Deficiencies of Polavaram Project (contd.) VIKASA • Dam design & safety issues - underestimated submergence area? • Design assumption: 36 lakh cusecs flood would submerge 276 villages in AP • But, in Aug. 2006, only 28.5 lakh cusecs flood submerged 369 villages • Design max. flood of 50 lakh cusecs - likely submergence of 400 villages and affecting 2.5 lakh population • Sedimentation problem in Godavari River • likely significant reduction in projected storage capacity • Nizam Sagar and Sriram Sagar Projects lost 60% of live capacity in 50 years Therefore, need to consider suitable alternatives…
VIKASA III. The Alternative Proposal
First Principles of the Alternative Proposal VIKASA • Diversion of water from higher elevations feasible • Sabari, Sileru, Sokuleru, Pamuleru ( on left flank) • at Dummugudem Anicut (on right flank) • Water needs met through gravity only – no need for lift • Capturing reliable water sources feasible - perennial flow (regulated discharge) from hydroelectric schemes • Protecting stakeholder interest & meeting the water needs of all sides • Resource optimization & environment protection – lowering costs; minimizing social and environmental costs; utilizing existing canal network • Tunneling technology – recent advances • Overall approach for win-win solution: adhering to the Constitutional mandate - Directive Principles of State Policy and statutory/regulatory requirements
A • Left Flank : • through Tunnel + Canal from Sileru R. into Yeleru R. A B B • Right Flank : • Major Canal + Tunnel from Dummugudem Anicut. Balancing/Carryover Reservoirs (Storage) - on Sokuleru R. and Pamuleru R. C VIKASA Alternative Proposal to Polavaram
The Alternative Proposal (details) VIKASA • Left Flank : Proposed Scheme • 5,000 cusecs regulated flow available for 9 months at 700 ft MSL in Sileru R. - below Lower Sileru Hydroelectric Scheme • Flow can be diverted through Tunnel (20 km) + Canal from Sileru R. into Yeleru R. – linked to main canal • Yeleru Project can serve as storage reservoir • Will fully meet irrigation and water supply requirements of Visakhapatnam & ors. (100 TMC water) – by gravity only • Hydropower generation possible by harnessing fall of 500 ft A
The Alternative Proposal (details) VIKASA B • Right Flank : Proposed Scheme • Diversion fromDummugudem Anicut at + 165 ft FRL • 35,000 cusecs flow for 9 months i.e. 600 TMC available at 75% dependability at Dummugudem • Can divert 100 TMC for right flank irrigation + 80 TMC for transfer to Krishna basin • Entire water available through gravity only • Major Canal + Tunnel (approx. 40 km) to cross Godavari-Krishna ridge
The Alternative Proposal (details) VIKASA • Downstream : Supplementing Godavari Delta in case of shortfall • - Balancing/Carryover Reservoirs (Storage) - on Sokuleru R, Pamuleru R & other minor basins • - Total storage up to 25 TMC for exigencies of delta, drinking water requirements • Projected downward trend in irrigation water demand for delta - conservation of water through modern irrigation, cropping methods (eg: ‘Sri’ paddy cultivation) • These reservoirs actually serve as water bodieswildlife requirements C
Benefits of Alternative Proposal - Summary VIKASA • Sustainable model for development; Win-Win Solution for all stakeholders • Necessity of Polavaram Reservoir dispensed with • Submergence of forest and tribal lands avoided • Displacement of people avoided • Assured water for all sides : left flank, right flank & delta/downstream • Entire scheme based on gravity flow only – no need for lift; significant cost savings • Hydropower generation feasible • In conformity with all environmental and project norms • Inter-region, inter-state disputes avoided Harmonious and optimal reconciliation of needs of various stakeholders + protecting the environment
Alternative to Polavaram - at this stage? VIKASA Yes, Alternative to Polavaram Project can be adopted even now. Mandatory project clearances not yet obtained!Main dam structure and storage structure not constructed anyway – are not inevitable SC’s Central Empowered Committee (CEC): “…there is a strong case for a second thought…CWC should take into consideration suitable alternatives…” On previous occasions too India dropped projects for better alternatives: • Silent Valley Project, Kerala - proposal in 1928, project initiation in 1958, dropped in 1983); eco-friendly alternatives taken up • Heran Reservoir in Gujarat
Summary of major arguments VIKASA
Why consider Alternative Proposal to Polavaram? from… to… It is time for a WIN – WIN SOLUTION for all Stakeholders VIKASA
