As drinking water sources people in Paikgacha (an Upazila which is located at Khulna, Bangladesh) use shallow tube-well, deep tube-well, Pond Sand Filter (PSF) and rain water harvesting. PSF is popular option of potable water supply in coastal problem areas .Although modified PSF has not been implemented in this area. Mainly due to high contents of Arsenic and Iron in shallow tube-well and salinity in deep tube-well, people prefer PSFs which treats surface water. In studied area the water quality parameters from PSFs are not fully satisfactory. Although removal efficiency of PSFs of Color, Turbidity is somewhat satisfactory but TC, E.Coli, suspended solids are less; this is due to lack of proper management & operation of Pond Sand Filter and pond. Performance assessment of PSFs was done in terms of quality of filtrated water and pond water. In this study six PSFs and six ponds are taken into account. Field visit shows among the studied six ponds, three ponds are badly managed and other three ponds are managed nicely. Besides number of PSFs compared to population is less so it hardly meets the demand of the people. Due to lack of technical knowledge and awareness, these PSFs are not performing well. This study aims at present drinking water pattern and scopes, people’s perception about PSF, performance analysis of existing PSFs and to address the associated problem in PSFs and pond management. Then finally provides recommendation to recover associated problem.
