MANUAL FOR EMPTYING BIODIGESTER TOILETS

Globally a huge number of people rely, for their sanitation, on non-sewered or onsite systems, which generate a mix of solid and liquid wastes generally termed faecal sludge. Faecal sludge (FS) is the general term given to undigested and partially digested slurry or solids resulting from storage or treatment of blackwater or excreta. In lowincome urban communities and rapidly expanding cities, faecal sludge represents a growing challenge, generating significant adverse public health and environmental risks. Without proper management, faecal sludge is often allowed to accumulate in poorly designed pits, is discharged into storm drains and open water bodies, or is dumped into waterways, wastelands, and unsanitary landfill sites. Only a small percentage of faecal sludge is managed and treated appropriately.
