Survey investigation for possibilites of making Infiltration well from authorised agency and if construction of Infiltration well is not possible than design, drawing, testing of bearing capacity, hydrological, geological survey and construction of water tight circular R.C.C. Dry Intake well cum pump house at the bank of river Mandakini near Tilwara nagar Panchayat with R.C.C. approach bridge of approximate 15 m length and 2.5 m width to withstand safely the river current (last 30 year)/ discharge, seismic/wind or all other natural effects and suitable for taking approximate 2.50 MLD raw water discharge(in 16 hours), including supply of all material, labour, T&P etc. required for proper completion of work. 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 Mandakini river Near Tilwara nagar Panchayat) 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.
