Actions might include installing household filter technologies and developing as rainwater harvesting systems, shallow wells and pond filtering systems.
Communities are given the tools and the opportunity help design and choose basic technologies that can be gradually upgraded, like rain water harvesting systems, shallow wells and pond filtering systems.
Many options included well tested and switching, use of deeper wells, surface waters after preservation and treatment, sanitary dug wells, river sand filters, pond sand filters, rainwater collection and storage, household scale arsenic filtration, large scale arsenic filtration, and rural pipeline water supply.
Mitigation options such as piped water systems, rainwater collection, dugwells, As filters, and pond sand filters are utilized by a very small proportion of the population [ 13, 14].
An estimated total of 6268 dug wells, 3521 pond sand filter (PSF), 13,324 rain water harvester (RWH), 74, 809 deep well (DW), 3,771 arsenic iron removal filters (AIRF), 33 Pipe water supply, 5,080 slow sand treatment (SST), 133 DSP totaling 106,939 mitigation options were constructed by different stakeholders (13).

Households are mainly dependent on rainwater harvesting, pond sand filter (PSF), and rain-fed pond water for drinking purposes.
This study investigates existing water supply scenario, and evaluates the performance of pond sand filter (PSF) in meeting drinking water demand of Dacope Upazila in southwest coastal Bangladesh.
