A two-page summary of a survey conducted by Inter Aide in 2010-2011 in 3 districts of Sierra Leone highlighted that among 2028 hand-dug wells visited, 45% of them were not delivering water permanently all year long. The paper looks to understand one of the main causes of wells’ drying in Sierra Leone, through an analysis of a water table movements.… Read More

Boreholes in Sierra Leone must be constructed to be “cost-effective”. This means optimum value for money invested over the long term. Boreholes are drilled to function for a lifespan of 20 to 50 years. The lowest cost borehole is not always the most cost-effective, particularly if construction quality is compromised to save money. Poor construction quality including lack of proper borehole development can lead to premature failure of the borehole or contamination of the water supply. Boreholes that are subsequently abandoned by the users as a result are not cost-effective. … Read More

The consumption of packaged water (PW) in bottles and sachets has grown rapidly worldwide, particularly in many West African countries, such as Sierra Leone, that presently lack mechanisms to effectively monitor and regulate the manufacture and sale of packaged drinking water products. While many consumers view PW as a relatively affordable, accessible, and safe source of drinking water, without effective regulation and consistent monitoring to ensure their safety, PW has the potential to pose a risk to public health.… Read More

This study examined the microbiological and chemical quality of a representative sample of packaged sachet water products in Freetown, Sierra Leone at packaged water manufacturing facilities and at points of sale. Packaged drinking water (PW) sold in bottles and plastic bags/sachets is widely consumed in low- and middle-income countries (LMICs), and many urban users in sub-Saharan Africa (SSA) rely on packaged sachet water (PSW) as their primary source of water for consumption. However, few rigorous studies have investigated PSW quality in SSA, and none have compared PSW to stored household water for consumption (HWC).… Read More

The outbreak of Ebola virus disease in West Africa in 2014 is the worst single outbreak recorded, and has resulted in more fatalities than all previous outbreaks combined. This outbreak has resulted in a large humanitarian effort to build new health care facilities, with associated water supplies. Although Ebola is not a water-borne disease, care facilities for Ebola patients may become sources of outbreaks of other, water-borne, diseases spread through shallow groundwater from hazard sources such as open defecation, latrines, waste dumps and burial sites to water supplies. The focus of this rapid desk study is to assess from existing literature the evidence for sub-surface transport of pathogens in the context of the hydrogeological and socio-economic environment of Sierra Leone. In particular, the outputs are to advise on the robustness of the evidence for an effective single minimum distance for lateral spacing between hazard sources and water supply, and provide recommendations for protecting water supplies for care facilities as well as other private and public water supplies in this region.… Read More
