Bulk water supply system The main source of existing combined water supply scheme to Kumta Honnavar town is from Aghanashini River & commissioned during 1998. The source is at a distance of 20Km & 36 Kms to Kumta & Honnavar towns respectively. The combined scheme is designed for 7.02 MLD & 6.60 MLD quantum of water respectively to Kumta & Honnavar Towns. The water is lifted from 300 HP Deep well Turbine pumpsets located at Deevalli head works to the WTP of capacity 13.62 MLD located at Santhgal. Further water will flow by Gravity to Kumta by the combined PSC pipeline and a tapping has been given to Honnavar from main line at Kumta near Gibbs Circle. Further from this tapping point a separate PSC feeder main will run to Honnavar and water will be collected in the Sump at Karkina at Honnavar. From this sump water will be pumped to the GLSR at KHB colony and water will be distributed to the city. No zoning has been done. At present the scheme is being maintained jointly by the TMC Kumta & Town panchayat Honnavar. 2.2. Distribution Networks Majority of the distribution system comprises of PVC pipes of 90 mm to 110 mm diameter and CI pipes of 150 to 200 mm diameter. The total length of distribution network is about 25 Km. 2.3. Customer Connections The town has over 2300 no. of house service connections. There are 2120 domestic connections and 180 non-domestic connections & the proposed connections 4120 Nos. (Total connections including existing connections is 6420 Nos) 2.4. Present Service Levels The town is being supplied with a water supply daily. The Town Panchayat Honnavar is not getting its required water demand due to power interruption at Head works & pipeline repairs problems. 2.5. Current Operating Financials At present flat rate of Rs. 80/- per month for domestic & Rs. 160/- per month for non-domestic connections is being billed by the TP, Honnavar. (PNo.115/24). 3. Service Improvement Project In the letter no.245/2012 Dt: 27/06/2012 the local MLA has requested the KUWS&DBoard on the pressure of public for frequent interruption of water supply to give separate water supply facility from the River Sharavati as source to Honnavar town. The source is perennial and the Gerusoppa Hydro power project Dam is situated at a distance of 3.0 Km upstream of proposed Head works. The tail water discharge through minimum 1 to maximum 4 Tubines is also continuously available during the period of summer. The Linganmakki Major Karnataka Hydro power Project Dam discharge tail water is fed to the Gerusoppa Dam. The future water demand is assessed based on factors like demographic growth, service levels, growth of domestic demand and losses in the network, in compliance with CPHEEO guidelines. As per 2011 census the population of Honnavar town is 19,109(PNo.124). The prospective population is 22,300 & 28,800 for the intermediate year 2030 & ultimate year 2045 respectively(PNo.130). Considering the rate of supply as 135 LPCD, the water demand works out to 3.23 MLD (2015) Intermediate demand is 3.64 MLD (2030) and Ultimate demand is 4.04 MLD (2045) (PNo.130). The 2011 census the population of 9 Grama Panchayath’s is 46,437. The prospective population is 51,400 & 55,700 for the intermediate year 2030 & ultimate year 2045 respectively (PNo.130). The project is envisaged to provide assured bulk water supply to the town from river Sharavathi which is perennial by constructing a new headwork’s at Mahime Village, providing & laying 406 mm dia M S raw water rising main, construction of 4.40 MLD WTP . The distribution network is zoned into District Metered Areas (DMAs). Based on principles of pressure zoning and number of customers; DMAs are demarked and ensured that the supply demand at any given point of time is achieved. Installing new metered connections to all customers to achieve full coverage is proposed. Management improvements for establishing computerized billing and collection systems including service performance monitoring and undertaking active leakage control have been proposed to ensure sustainable service delivery and revenue recover. 4. Capital Cost of Project The capital cost proposed for infrastructure and management improvements is Rs. 12276.00 Lakhs.. The financial analysis assumed 80% grant,10% from GoK and 10% from ULB and RDPR share on prorate basis results in weighted average tariff of Rs. 3.09 per kilo liter from the completion of project to achieve 38.84% Internal Rate Of Return (IRR) for 30 years. The service improvement project is submitted for financial assistance from UIDSSMT.

Brief Description of Proposed WSS: It is proposed to draw the Water to Honnavar town from the Sharavathi river at Mahime Village in Honnavar town. A Intake well of 4.0 mtr size & Jackwell cum pump house of 8.0 mtr dia has been proposed on the bank Sharavathi river at Mahime Village in Honnavar town. It is proposed to pump raw water from the jackwell at Mahime Village to 4.40 MLD capacity WTP @ Honnavar town at Prabhath Nagar at a distance of 23000 m. A new WTP of 4.40 MLD capacity has been proposed to be constructed near Prabhath Nagar and 9 en-route villages will be benefitted by this project with Pressure filters. Benefit of the Project :- To avoid the distribution losses, improve service to the consumers and for monitoring & measuring the water supplied, 24x7 water supply distribution Network with HDPE pipeline has been proposed along with Bulk Water meters & Domestic Water meters including House Service Connections.
