The Sustainable Development Goal (SDG) target 6 aims to tackle challenges related to drinking water, sanitation and hygiene as well as to water-related ecosystems. Bangladesh has done remarkably well in ensuring access for its population to drinking water and sanitation over the years. Before the discovery of arsenic, the country enjoyed almost universal access to drinking water. Open defecation has been almost completely eradicated while access to ‘improved’ sanitation increased dramatically from 30 percent to 65 percent in rural areas over the period from 2000 to 2017. 1 Still, significant challenges remain in rural WASH in order to meet the SDG target 6 service standards that are recommended for maximizing human capital outcomes. Bangladesh has still a long way to go to meet the Sustainable Development Goal (SDG) of providing universal access to safe water and sustainable sanitation by 2030. The World Bank WASH Poverty Diagnostic examines the remaining challenges in ensuring access to safe water, sanitation, and hygiene. Tackling these challenges is crucial because safe water and sustainable sanitation has a strong positive impact on health, education and development. Living in unsanitary environments increases the prevalence of stunted growth and stifles economic development. Without WASH, it will be difficult for the workers of the future to acquire the cognitive and socio-emotional skills they need.
