ABSTRACT

India is one of the leading countries in drinking water scarcity issue. Even though India is abundant in natural water bodies and precipitation, most of this water is unsuitable for human consumption. The drinking water scarcity of any locality can be solved using cheap and readily available materials. This paper deals with solving the drinking water scarcity of 31st mile in Mundakayam by creating slow sand filter. The slow sand filtration system is modified with activated coconut shell charcoal, activated bamboo charcoal and chitosan as filter media. Water filtration system with different media is a cost-effective method to improve household water quality without using electricity or wastage of water.
