Inner diameter of well shall be 6.0 metre. Height of well is approximately 15.0 metre ( from lean water level to 2.0 M above H.F.L. of Alaknanda river near Jilasu Village) and depth of foundation below G. L. is assumed 8.0 M, which is liable to change according to geo-investigation, structural design and site conditions and HFL of river in last 30 year. Height of pump house will be 4.00 m (including space required for Motors, HT Pannels etc.). Atleast six inlets (on different levels/heights) with a common header should be installed at/above intake floor with stainer to tap river water, pipe arrangement for drazzing pump, M.
