Trial run for the much-awaited Cauvery IV Stage Phase II, which is expected to quench the thirst of erstwhile City and Town Municipal Council areas which have been brought under the BBMP, is all set to begin from next week. The Bangalore Water Supply and Sewerage Board (BWSSB) has taken up Cauvery IV Stage II Phase works at a cost of Rs 3,383.

70 crore with financial assistance from Japan International Cooperation Agency (JICA) to supply drinking water to over 12 lakh people in seven erstwhile City Municipal Councils - Rajarajeshwarinagar, Dasarahalli, Bommanahalli, K R Puram, Mahadevapura, Byatarayanapura, Yelahanka, and one Town Municipal Council Kengeri.

The BWSSB’s engineers are ready for the trial run as the work of laying 174 km pipeline is almost complete. BWSSB’s Chief Engineer (Cauvery Project) Narayan said, “Water to Cauvery I, II, II and IV Stage, Phase I works, is being currently pumped to T K Halli pumping station from Netkal Balancing Reservoir(NBR).

 As the load on NBR high, the works to draw water to T K Halli pumping station through 16. 5 km pipeline through gravity from Shiva Balancing Reservoir (SBR), is complete.

” “The important works such as setting of raw water treatment plant at T K Halli to treat 500 million litres of water a day (MLD) and laying 174 km of pipeline (including 89 km which runs into the city) are complete.  We will start the trial run from the coming week.

 Power testing of the pump house motors dry run and wet run will be done,” he said.  “All pipes will be inspected thoroughly and cleaned by disinfecting it with bleaching powder.  This will free the pipes from debris, muck, and other things accumulated inside the pipes.

 Water samples will be collected and checked for potability,” he said. They will be sent to private labs to double check the quality.

 On reaching the city, water will be diverted into seven ground level reservoirs (GLRs).  “The cleaning work may take one-and-a-half months.  Later, we will pump 100 million litres of water per day,” BWSSB’s Engineerin- chief T Venkatraju said.
