1
Integrated Plan for Sustainable Development of All the Regions of Andhra Pradesh

  • Vedire Venkat Reddy
2
Andhra Pradesh Rivers and Projects
  • Godavari
    • Manjira, Maner, Pranahita, Indravati, Kinnerasani, Sabari
    • Sriramsagar, Floodflow canal, Kakatiya canal, Godavari north canal
  • Krishna
    • Bhima, Tungabhadra
    • Srirsailam project, Nagarjunasagar project, Prakasam barrage
3
Current Situation
  • Godavari
    • 1480 TMC alloted
    • 70% of total flows wasted in to the sea
    • Copious flows available only 3 months, July-September
    • 80% of AP catchment area is in Telangana
    • Major projects – Sriramsagar
4
Current Situation
  • Krishna
    • 800 TMC alloted, drawing 1100 TMC
    • Available August-November only
    • Srisailam water being used for Telugu Ganga, irrigation and for power.
    • Nagarjunasagar - Not being used for irrigation of the originally intended regions
5
Integrated Plan
  • Short term plan (2 yrs)
  • Long term plan (10 yrs)
6
Short Term Plan
  • Proposed by Dr. Sriramakrishnaiah, then Technical advisor to Government of Andhra Pradesh
  • Connect Godavari and Krishna
  • Lift irrigation - utilize existing rivers and major streams as water carriers
7
Short Term Plan
  • Start from Kaleshwaram below Pranahita and lift up to Krishna-Godavari ridge in a number of stages
  • Link canals connecting Akheru, Paleru, Yashwantapuram, Aleru and Musi
  • Connect to Nagarjunasagar upstream
  • Potential to draw 197 TMC at an average discharge of 419 cumecs
8
Short Term Plan
  • 59 TMC @ 140 cumecs
  • 1 TMC drinking water to Warangal city
  • Lift at 32 stages and irrigate 7.58 lakh acres
  • 378 MW (1226 million units) required for lifting
  • Estimated cost is 1560 crore rupees
9
Short Term Plan
  • Can extend scope to 4 times of original plan
    • 59x4 TMC = 236  TMC
    • Irrigate 25 lakh acres, only additional cost is power required for lifting
    • 378x4 MW = 1512 MW required for lifting
    • Estimated cost is 1560 + 532x3 = 3156 crore rupees
10
Short Term Plan
  • Meets the short term needs of the people
  • Water only available June – November
  • Will need reservoirs for year round availability. We need  a long term plan
11
Long Term Plan
  • Key points
    • Build reservoirs and barrages on Godavari
    • Create links to Krishna and create a water grid serving the needs of the three regions of Andhra Pradesh all year around
    • Harness waters of Vamshadara, Nagavali, Janjavati and champavati for north coastal AP

12
Long Term Plan
  • Two reservoirs
    • Pranahita to KanthalpallI, about 105 km is mostly hilly and forest area
    • Ideal location for reservoirs
    • Propose one reservoir at Kaleswaram and the other at Kanthalapalli (above Eturnagaram)
13
Long Term Plan
  • Kaleswaram dam
    • In line with the ridge between Pranahita and Indravati
    • FRL – 135 m
14
Long Term Plan
  • Inchampally not a suitable location
    • At FRL 112.77 m, 60% submersion in Maharashtra and Chattisgarh and 40% in Andhra Pradesh
    • Reducing FRL to 105 m for reducing submersion will give only 100 TMC
    • Instead, FRL of 105 m at Kanthalapalli will provide 300 TMC and reduce submersion as well
15
Water Grid
16
Building Water Grid
  • Construct 6 barrages along Godavari between Kanthalapalli and Polavaram
  • Link 1 from Kaleswaram to Nagarjunasagar upstream
  • Link 2 from upstream of Kanthalapally dam to the upstream of tail pond below Nagarjunasagar
  • Link 3 from upstream of Polavaram barrage to the upstream of Krishna barrage


17
 Water Grid
  • Costs 37,000 crores
  • 1500 MW required for lifting
  • Must be taken up as a national project
  • Planning sustainable river valley projects requires intricate multidisciplinary study
  • Can learn some other projects like Oswan dam in Egypt, 3 Gorges in China


18
Water Grid Benefits
  • 550 TMC of water irrigates 30 lakh acres of Kharif paddy and 25 lakh acres of Rabi
  • 3000 MW generated at Kaleswaram and  Kanthalapally dams and Dummugudem, Polavaram and other barrages on Godavari
  • Power spent on lifting water to supply into the Krishna catchment area can be recovered back at the check dams erected across the tributaries of Krishna through hydel generating plants



19
Water Grid Benefits
  • About 3 lakh pump sets currently in use can be substituted by Godavari waters. This is a 450 MW saving (assuming 50% load factor)
  • Full fledged water grid will meet the requirements of Karimnagar, Warangal, Khammam, Nalgonda, West Godavari, Krishna, Guntur, East Godavari and Vishakapatnam


20
Water Grid Benefits
  • Krishna waters thus saved can be used
    • For Mahbubnagar and Nalgonda by creating flood flow canal on Jurala
    • 100 TMC to Rangareddy and Mahbubnagar through a project on Bheema
    • 60 TMC to Nalgonda through SLBC
    • 200 TMC can be released to Telugu Ganga, SRBC Veligonda etc to Rayalaseema


21
Water Grid Benefits
  • Hyderabad will continue to be on Madhava Reddy lift irrigation scheme
  • Waters of Manjeera river will be released to irrigate Rangareddy, Medak and Nizamabad
  • 150 TMC of water during flood season (July to September) can be offered to the south to solve the acute irrigation problem under Cauvery. A reason for Central Government to take this up as a national project


22
Other Projects
  • Harnessing the waters of Vamshadhara, Nagavali, Janjavati and Champavati rivers would meet the requirements of North Coastal districts of AP – Srikakulam and Vijayanagaram
