Pit to Roadside Fecal Sludge Conveyance
Approximately 4.5 billion people across the world lack access to safely managed sanitation. In communities without institutionally managed sewage and sanitation systems, pit latrines are the standard solution. However, these latrines are difficult to properly maintain and empty; often informally emptied by manual scavengers, these pits are frequently a source of environmental contamination and disease in the communities which utilize them. The Bill & Melinda Gates Foundation is working to provide safe, affordable fecal sludge management to populations in Sub-Saharan Africa and South Asia, through a variety of projects including the reinvented toilet. Gates-SCOPE focused on the area of fecal sludge conveyance, developing a flexible, low-cost mechanism to transport sludge from pit-side emptying units to road-side portable processing units.
