BENGALURU: The government has decided to supply 10 tmc ft of additional water to Bengaluru city to save Cauvery water, which is heavily used in agriculture.
The new settlements and areas of the city, including the 110 villages covered by the Brihat Bengaluru Mahanagara Palika (BBMP), need more water. Thus, the Bengaluru Water Supply and Sewerage Board (BWSSB) had submitted a proposal to the government that surplus water should be allocated. After reviewing this, the government directed the Cauvery Irrigation Corporation to review the feasibility of supplying additional water and submit a report.
A committee led by technical experts conducted a review and found that 'rice, sugarcane and other agricultural crops are using much more water than required. If this is reduced, more water can be provided to Bangalore', the report said. Based on this report, the government has given in-principle consent to the BWSSB and suggested to increase the capacity to use the surplus water.
Cauvery 5th phase project to supply water to Bengaluru is in the final stage and it is planned to supply water to 110 villages in April. On this occasion, it is intended to start the works to increase the capacity to collect and supply additional 10 TMC feet of water,'' BWSSB President Ramprasath Manohar informed.
BWSSB uses 24 TMC feet of water from Cauvery annually, of which 20% is classified as 'Consumptive use'. That is, if using the water obtained from the river, 20% of it is returned to the river itself, there is a chance of getting that amount of water in excess. On this basis, the government has agreed to demand more water. Officials explained that most of the water used in the city is joining Kaveri River through Vrishabhavati, Arkavati and canal-valleys.
Consent in principle: Ramprasat
A proposal was submitted to the government that due to the increase in the population of the city and the development of the areas, the allocation of water should be increased. BWSSB Chairman Ramprasath Manohar said that an in-principle consent has been given to save 10 TMC feet of water under the Cauvery Irrigation Corporation.
Annual allocation of Cauvery water to the city
- 24 TMC Ft: Allotment as per Supreme Court judgment
- 19 TMC Ft: Water currently being used
- 5 TMC Ft: Water available for stage 5
- 34 TMC Ft: The total water allocation is 10 tmcft which the government has now agreed to
Use of Cauvery water in the city
- 1,450 million litres: Daily supply of water in the city
- 1.6 TMC Ft: Water being supplied to the city every month
- 750 million litres: Additional water supplied daily on completion of 5th stage
- 2.4 TMC Ft: Current and Phase 5 water supply to the city every month
