Over 60 percent of the population of Tajikistan - close to the Afghan border - lives on less than $2 dollars a day and only 58 percent have access to clean and safe water.
The quality of water supply, sanitation and housing services have deteriorated due to the lack of government funding. Routine maintenance work is not carried out and drinking water is drawn from contaminated irrigation canals and ditches. Annually, almost half of the population contract one or more water borne diseases.
Habitat for Humanity has joined forces with the local NGO Nakukor to adapt and implement a low-cost solution to the problem–the “bio-sand” water filter. It consists of a concrete container with graded sand and gravel, topped with a diffuser and bio-layer. As water passes though the various layers, bacteria are filtered out. This technology is simple yet effective and can be easily assembled and maintained by the families. One filter costs $163 and provides clean drinking water for two families. When the family repays the costs, money goes into the revolving fund and filters can be installed in other households of the community.
