MAJOR ACHIVEMENTS
• SHIGGAON LI SCHEME COMMISSIONED
• FIRST OF ITS KIND : 9900 HA UNDER SPRINKLER IRRIGATION
• MAJOR ACHIVEMENTS YETTINAHOLE PROJECT • A Scheme for diversion of flood water from west flowing streams in the upper reaches of western ghats near Sakleshpura to provide drinking water to drought prone areas of Tumkur, Bangalore rural, Ramnagara, Kolar & Chikkaballapura districts (East)
CHALLENGES IN HARNESSING WEST FLOWING STREAMS It is difficult to harness water available in Western Ghats due to Environmental constraints owing to Presence of Western Ghats. Engineering challenges Economic viability Hence, an effort has been made to divert only a meager percentage of water that too from the upper reaches of the Western Ghats close to the plateau.
12
YETTINAHOLE SCHEME AT A GLANCE • The streams that have been proposed to be harnessed are listed below. 1. Yettinahole 2. Yettinahole Tributary-1 3. Yettinahole Tributary-2 hole 4. Kadumane hole – 1 5. Kadumane hole - 2
6. Yettinahole lower reach 7. Kerihole 8. Hongadahalla
YETTINAHOLE SCHEME AT A GLANCE
Extent of Watershed Area in Western Ghats of Karnataka – 24,530 Km 2 Available Catchments – 13 Present Scheme considers tapping streams which are originating from upper reaches of Western Ghats near Sakleshpur having an elevation above 730 m.
It is clear from the above schematic representation that a meager percentage of water is being planned to be diverted from West to East for the purpose of meeting the drinking water 14 requirement in the drought prone areas in the present scheme.
YETTINAHOLE SCHEME AT A GLANCE The present scheme envisages :• Simple diversion structures across the stream keeping the maximum water level restricted within the flanks of the streams. • A suitable intake structure and lifting arrangements on the foreshores in order to lift the water only during peak monsoon / floods. • Dedicated raising main (pipes) buried under the ground to convey lifted water from the pump house.
15
YETTINAHOLE SCHEME AT A GLANCE • The pipeline will be routed parallel to existing corridors in order to minimize the opening of the new corridors. • The Raising mains will be taken from the intake structure up to Haravanahalli near Sakleshpura beyond which it is planned to have a gravity canal (250 km) to convey the water up to Tumkur. • The alignment of the canal has been planned along the ridge line bifurcating the Cauvery and Krishna basins. • A raising main for a length of 8.1 km has been planned to convey the water to a16storage Reservoir, near Devarayanadurga, with a capacity of about 10 TMC.
YETTINAHOLE SCHEME AT A GLANCE • From the reservoir two raising mains have been proposed one towards Chikkaballapura (88.2 km) and other towards Kolar (55.9 km) to provide drinking water needs and filling of 198 and 139 MI/ZP Tanks respectively in the above Districts.
Cost • Based on the line estimate, the Government of Karnataka has accorded Administrative approval vide GO No ಜಸಂಒ 203 ವಿಭ್ರಾರಾಇ 2012 dated:13.07.2012 - costing about Rs.8323.50 crores for diverting about 17 24.01 TMC of water.
YETTINAHOLE PROJECT
UN-FAO PROPOSAL FOR THE CENTRE OF EXCELLENCE IN INDIA: • •
• • • • •
Key issues ; improving water governance at the level of irrigation systems and river basins, as well a ground water and trans boundary levels; adopting a multi-sectoral strategic planning and management approach to revision of food security, agriculture, water and environment policies and investment strategies; adopting demand driven and service oriented irrigation development and management strategies; modernising irrigation systems; enhancing water productivity for both rain-fed and irrigated production; enhancing environmental protection; and focusing on agro-ecosystems and populations particularly at risk, such as in tropical deltas and in arid or semi-arid areas.
