People residing in the Flouride affected Tapan and Gangarampur Blocks are going to have flouride-free safe drinking water through two separate Piped Water Supply Schemes being implemeneted in Dakshin Dinajpur district, covering a total 1,547 habitations in 482 villages. A population of 5.13 lakh (Census 2011) will be benefitted from these two Piped Water Supply Schemes. The targeted ultimate design population is 6.14 lakh in the design year 2043. Sub-surface water from River Punarbhava, which is flouride-free, will be extracted through two Infiltration Galleries. the sanctioned Capital cost of the schemes for Tapan and Gangarampur stands to Rs. 165.50 crores and Rs. 145.01 crores respectively.

Asian Development Bank is funding three Mega Piped Water Supply projects in the flouride occuring areas of Bankura, Arsenic-affected blocks of North 24 Parganas and South 24 Parganas as well as in certain saline zones in East Medinipur with 70:30 financial assistance with the State Govt. The three Mega projects are, - (a) Piped Water Supply Schemes for Bankura (Phase-II) covering 8 blocks at an estimated cost of Rs. 1238.40 crores to benfit a population of 11.03 Lakh (Census 2011) (b) Surface water-based Piped Water Supply Scheme for Arsenic affected areas of Haroa, Rajarhat and Bhangar-II blocks of the districts, North and South 24 Parganas at an estimated cost of Rs. 686.95 crores to benefit a population of 5.26 Lakh (Census 2011) (c) Surface water-based Piped Water Supply Scheme for the saline affected areas of Nandakumar, Chandipur, Nandigram-I and Nandigram-II Block of Purba medinipur district at an estimated cost of Rs. 811.38 crores to benefit a population of 7.82 Lakh (Census 2011).
