Arsenic contamination in drinking water is a health threat for many people in Bangladesh. Surveys have demonstrated that millions of people are exposed to high arsenic concentration in drinking water in arsenic prone rural areas. The government has recommended the use of piped water systems as an appropriate arsenic-safe drinking water technology. Many piped water systems have been installed in arsenic prone rural areas since 2001. Water quality provided by those systems, their financial sustainability and water users acceptance are not well known. This study investigated the technical, financial and social performance on those systems. Fifteen sites were selected and visited. Among them, seven were investigated in detail with water sampling and testing, interview with households and water management committees and focus group discussions. E. coli, turbidity, arsenic, iron and manganese were tested. Financial contributions, operation and maintenance costs of the systems, perception of water users on water quality and levels of water services were also analysed. In addition, impacts of site selection, water source identification and evaluation, design and construction, operation and maintenance aspects on piped water systems performance were assessed. Among the seven case studies, site selection was well done in all cases, water source evaluation and design were well implemented at all sites except one site, and design was well done in all sites except one case. Routine maintenance was well conducted in some schemes, others need improvement. E. coli concentration in public taps and households storage containers can be classified as “low risk” to “intermediate risk” Arsenic, manganese, iron, pH and turbidity complied with Bangladesh standards except at one site where turbidity and iron content were above Bangladesh standards. Financial contributions of households cover operation and maintenance costs in all schemes except for one; design and financial contribution are very determinant for the performance of a piped water system and water users acceptance.
