Cauvery water supply stage V is set to proceed. The BWSSB has finalized the consultancy firms.
The Government of Karnataka had directed the Bangalore Water Supply and Sewerage Board (BWSSB) to re-direct Cauvery river water to the five zones under the Cauvery Water Supply Scheme-Stage V plan. This was kept in cold storage as Stage IV was under process.
Cost of the Project of Cauvery water supply scheme V
The project is worth Rs.5500 crore and this includes construction of 7 ground level reservoirs. The reservoirs will be at Gottigere, Kadugodi, Chokkahalli, Singapura and Lingadeverahalli.
Cauvery Water Supply Scheme (CWSS)-Stage V:
The scheme is primarily the construction of a complete water supply and sewerage system. This is to be systematically undertaken in the 110 villages area in 2 phases – 500 MLD to be supplied in Phase 1 and 225 MLD in Phase 2.
The larger plan is to direct the surplus water from the project to core areas and 8 Urban Local Bodies (ULB) in the next decade 2024-2034.
A meeting was held last year. It was revealed in the meeting that putting down of the pipelines is 100% complete in nine villages. The House Service Connections (HSC) activity is in progress for 17 villages, for which 7.5 MLD has been allotted.
Cauvery water supply scheme – flow of water
In Cauvery water supply scheme Stage V, water from Shiva Anekattu or Shiva Balancing Reservoir flows into Netkal Balancing Reservoir. It is then pumped to Toraikadanahalli water treatment plant. Treated water from Toraikadanahalli is then pumped into Bengaluru through pipelines and Harohalli and Tataguni pumping stations.
