Observation of supply water quality and sanitation system in different slum areas of Dhaka City

Abstract

This study focuses on the problems with access to clean drinking water and sanitation in a few Dhaka metropolitan slums, namely Jhilpara, Chalantika, Korail, BNP, and Kalyanpur. The study examines the sanitary infrastructure in these locations and looks into the quality of the water that is supplied for drinking. The provision of basic public services has become more challenging due to the uncontrolled settlements' explosive expansion. These slums' residents frequently experience severe water shortages, low- quality water, and inadequate sanitary facilities, all of which raise health risks and aid in the spread of illnesses that are transmitted by water. The purpose of this study is to evaluate the condition of these slum communities' sanitation systems as well as the supply water quality, in every slum, three distinct locations were chosen to gather samples in order to guarantee a reliable evaluation of the water quality. Additionally, a survey was carried out to evaluate each slum's sanitary infrastructure. The quality of the drinking water that was supplied was assessed using a number of parameters, including pH, turbidity, electrical conductivity (EC), temperature, total dissolved solids (TDS), total suspended solids (TSS), color, iron (Fe), nickel (Ni), lead (Pb), arsenic (As), and Escherichia coli (E. coli).
