We investigated the impacts of piped water on water quality, sanitation, hygiene and health outcomes in marginalized rural households of north-western Bangladesh using a quasi-experimental analysis. A government organization - the Barindra Multipurpose Development Authority (BMDA) - established a piped water network to provide these rural households with improved water as they have poor access to potable water. Using propensity score matching, the study compares a treatment and a control group of households to identify gains in water-sanitation, hygiene and health outcomes. We found that the BMDA piped water infrastructure had a positive impact on access to improved water and significantly reduced the distance traveled for and time spent on collecting drinking water. However, we found no improvement in the drinking water quality, which was measured by the extent of fecal contamination (E. coli count per 100 ml of water) at the point of use. The hygiene status of food utensils also did not show any improvement; food utensils were tested positive for E. coli in both the control and treatment group. Although access to BMDA piped water in the premises involves cost, it didn´t improve hygiene behavior: handwashing with soap after defecation and before feeding children. The treated households own larger water containers which implies that the intervention has had a clear impact on the quantity of water used for household purposes. However, we did not find evidence of health benefits, such as decreased diarrhea incidence of in under-five children, improved child anthropometrics stunting, underweight and wasting of children due to piped water use.

Open dumping of waste and discharging untreated wastewater into environment are key causes of environmental pollution in the developing world, including South Asian countries. Waste and wastewater however can be a source for recovering energy, nutrients and water if properly treated or recycled rather than a cause of pollution and diseases spread. The importance of adopting Resources Recovery and Reuse (RRR) technologies increases under growing demand for food and energy in contrast to depleting fossil fuel mines and groundwater reservoirs. However, institutional framework including the organizations and various stakeholders involved in the waste and wastewater management sectors, government policies and legislation, as well as financial arrangements and incentives to technological change play a pivotal role in adopting and scaling up RRR options. This study therefore focuses on institutional and financial aspects of challenges and opportunities for implementing RRR options in South Asia. It is argued that improving financial capacities, easing to obtain land use permits to expand RRR facilities, maintaining quality of RRR products (compost, biogas), and raising environmental awareness are imperative for the successful performance of the RRR projects in South Asia.
