Miscellaneous works like NH and railway crossings, horticulture, etc.
Proposed Solution:
The primary objective of the project is to provide safe & potable drinking water to all individual households in all villages and dhanies of Ladnu through tap water connection with service level of 55 liter per capita per day. The above project was initially designed on 55 lpcd so no change in the transmission/ transfer system is required. The above project was supposed to provide water through PSPs so necessary changes are proposed in such a way so as to enable supply through FHTCs.
For supplying water with minimum 7m residual pressure, provision of new cluster ESR are kept and for new proposed ESR provision of rising mains are also kept with electromechanical works.
History:-
The Phase II, Package-VIII (CDS-05) covered 97 Main Habitations of Ladnu Tehsil through PSPs and CWTs but without any provision for Other Habitations. The water demand for villages was taken @ 55 lpcd. The Water Supply Scheme was completed in year 2020. The existing distribution system is designed by taking peak factor as 3 and water is supplied through PSPs in main habitations only for a period of 1-2 Hours in a day while the other habitations (dhanies) are not connected with the system.
Existing FHTC Coverage & Proposed Works Presently in Ladnu Block, total 42093 FHTC are estimated for the year 2024 (Base year), out of which 10122 FHTC in 34 MH are being taken up by regular division. Therefore, remaining 31971 FHTC are proposed under this package.
