NKUSIP (Package I - Dharwad)Tranche I Sub-Projects in Haveri CMCInitial Environmental Examination39. From the analysis of the existing system it was observed that the immediaterequirement in this sector is developing a surface water storage which canstore water for the lean periods of 90 days. Further it was found that thedistribution mains and sub mains are not of the required sizes which requireaugmentation and the distribution network requires further extension insidethe city limit.40. In order to ensure the regular water supply during lean months, thealternative options studied werei) Construction of a barrage across Thugabhadra Near Guttalii) Identifying an impounding reservoir which can store water for summerrequirement41. Out of the above options, it was observed that construction of a barrageacross Thungabhadra is not feasible since the width of the river is too longand the plain topography at the intake will necessitate substantialinundation. Further this proposal will have impact on the existing interstate Krishna River water dispute and further the allocated fund is notsufficient to construct a new reservoir at this location. It was observed thatHeggere Kere - a lake of capacity 1400 ML located at 1.5 km away from theheart of the city located near to the new WTP can be converted to animpounding reservoir. It is proposed to pump the surplus water from riverVarada for 240 days in a year and utilize the stored water after treatmentthrough New WTP of the adequate capacity during lean months. Thisproposal was found to be the most feasible option which requires laying ofpipeline from river Varada to Heggere Kere and further from lake to newWTP along with necessary pumping arrangements.42. From the analysis of existing distribution network using Water GEMS V8XM Edition hydraulic modelling software it was observed that in zone 4 thedistributions system is having its capacity to meet the ultimate yeardemand. Zone 1, Zone 2 and Zone 3 have inadequately sized transmissionsystem and in order to improve the distribution system it was proposed todo rehabilitation in Zone 1, 2 and 3 to meet the requirements of year 2041for 6.5 km and extending network to un covered areas by laying 12.54 km ofdistribution network within the city limit. Other proposals along withTranche 1 include feeding OSHR at Netaji Nagar with dedicated feeder of10”.43. Further to cater the future demand, in 2026, the town has to plan for anKUIDFC19WSAPL
