The Detailed Project Report (DPR) of the proposed Ettinahole project is likely to be ready by June, and if everything goes as per the plan, the project implementation would commence by September this year.
The ambitious project, when completed, would supply water to the parched districts of Kolar, Chikkaballapur, Bangalore Rural and Tumkur.
Chief Minister D V Sadananda Gowda reviewed the progress of the project on Wednesday.
According to the project plan, 24.01 tmc ft of water from Ettinahole, Kadumanehole, Kerehole and Hongadahalla (all tributaries of Netravathi River) will be drawn by constructing eight small dams. The water will be pumped for 10 km up to Haravanahalli in Hassan. From Haravanahalli, the water will be flown to Tumkur for 233 km with gravitational force.
Again from Tumkur, the water will be pumped for 8.10 km to Devarayanadurga where a 10 tmcft- reservoir will be constructed. From the reservoir, the water will be pumped to Kolar and Chikkaballapur district, for a distance of 55.9 kms. The plan is to fill about 337 tanks in the two districts.
Besides, it has been planned to supply about 14 tmc ft of water to Tumkur, Koratagere, Madhugiri and Pavagada taluks of Tumkur district. The project also includes filling of Chamarajasagara, Hesarghatta lakes and providing water to Devanahalli industrial area. This apart, project envisages water supply to some towns in Hassan, Chikkamagalur and Chitradurga districts from Vedavathi River.
Kolar, Chikkaballapur, Bangalore Rural and Tumkur districts are the worst hit places due to depletion in ground water table. Ettinahole project. estimated to cost about Rs 7,000 crore. is the only ray of hope for them.
Speaking to reporters after the meeting, the chief minister said the government has plans to include Ramanagar district under the project. The project will be taken up as soon as possible to give relief to the affected people of the five districts, he added.
Water Resources Minister Basavaraj Bommai said the Maharastra government had not been able to release Koyna water to the State owing to political pressures.
