For Karwar and Ankola, the present source of supply is from Gangavali River at Honnahalli, which is situated at 42 km from Karwar town. The existing beneficiaries are Karwar and Ankola towns, BILT, Karwar Port, enroute villages and naval base (partially). The existing scheme, commissioned in 1975, was designed for a capacity of 40.90 MLD, which, however, yields only 20.00 MLD due to heavy leakages in the PSC gravity main of about 42 km and ultimately only one MLD of water reaches Karwar town. The total projected demand for water from all the existing beneficiaries is 31.20 MLD.
Karnataka Urban Water Supply & Drainage Board (KUWS&DB) has implemented a new scheme for rehabilitating the existing supply system itself, which includes construction of a 50 lakh litres capacity and an RCC mother tank near Navagadde, replacement of old valves, construction of 4.5 lakh litres sump, provision additional pumping machinery, strengthening 12km of 700 mm diameter PSC gravity main joints etc. This scheme involves laying of pipe across a ghat by pipe jacking, filter house, repairs to gravity main and providing DG sets etc. Further rehabilitation and upgrading the existing water supply distribution system for Karwar & Ankola towns is also implemented under the project
Capacity of proposed scheme: 12 MLD
Total investment: Rs 425.1 million
Status: Completed and commissioned. Supply of MS pipes for replacement of PSC gravity main commenced.
