On behalf of Oxfam, Arup have conducted a technical comparison study on Faecal Sludge Management at the Rohingya camps close to Cox's Bazar (CXB), Bangladesh. The aim of the study is to draw conclusions on best practice FSM for disaster relief, from evidence gathered through practical experience. The study used existing available data to inform the analysis and in many cases these datasets are limited. The findings from the report should therefore be treated as provisional and are relevant to the particular context of the situation at CXB.

Over 20 operational FSM sites were visited in CXB, constructed by eight different NGOs and using eight different technologies. The eight FSM technologies were:

1. Constructed Wetlands
2. GeoTubes
3. Lime (Three main types; lagoons, in barrel and three tanks)
4. Anaerobic Lagoons
5. Aerobic Treatment
6. Upflow Filters (Two main types; with and without pre-settlement)
7. Biogas
8. Anaerobic Baffled Reactors (ABR)

The FSM technologies were compared against a set of indicators including; cost, footprint area, speed of construction and commissioning, operation and maintenance issues, pathogen inactivation and resilience to natural disasters.
