Panaji: The state cabinet on Saturday approved shifting the proposed barrage and 50 MLD raw water pumping station from Mirabag to Panchawadi to ensure an uninterrupted supply of raw water to the drinking water treatment plant at Panchawadi in Shiroda, South Goa. The project is estimated to cost around Rs 228 crore.The proposal involves augmenting the Panchawadi dam to ensure a 100% dependable supply of raw water to the Panchawadi (Maishal) treatment plant by changing the site of the barrage and pumping station from Mirabag in Sanvordem to Panchawadi.The cabinet also approved constructing a 50 MLD raw water pumping station near the Selaulim dam, along the Selaulim irrigation project (SIP) canal, to augment the minor irrigation tank at Panchawadi.The plan involves drawing water from the Selaulim dam reservoir by constructing a pumphouse and installing pumps and motors near the main canal. The alignment of the gravity and rising mains, along with the designs and drawings, will be modified as required. Pipelines will be laid along the SIP canal within the acquired land and along the PWD road.

Additional materials will be procured as required under the new alignment. The barrage construction component will be dropped and replaced with the supply, laying and commissioning of 13.8 km of 700 mm-diameter DI pipeline.“These additional lengths are due to change of alignment/site.
