Faecal Sludge Treatment

In urban areas of Asia, Africa and Latin America, the excreta disposal situation is dramatic: every day, worldaround, thousands of tons of sludges from on-site sanitation (OSS) installations, i.e. unsewered family and public toilets and septic tanks – so-called faecal sludges – are disposed of untreated and indiscriminately into lanes, drainage ditches, onto open urban spaces and into inland waters, estuaries and the sea.
