In the Humanitarian Innovation Fund Gap Analysis for water, sanitation, and hygiene issues, field staff identified environmental management of surface water as an area of concern, although this was not reflected at a head office level. This difference of perspectives could be an under-reporting of this aspect of environmental sanitation to the global humanitarian community or a failure of experts to communicate the required response to surface water management in camps for displaced people.
Pit latrine linings for emergency sanitation facilities require different performance criteria from those for pits used in longer-term development work. Various international initiatives are currently under way to develop new methods of supporting the pits used for latrines in emergencies, but before a solution can be found, the problem needs to be defined. Current field guidance lacks the level of detail required by humanitarian workers to construct durable pits in a timely manner.
Lighting should be provided for WASH facilities in Humanitarian contexts according to several standards. Evidence for this and the practical budget, operational and management responsibilities are less clear. A three-country research project looking at the impact of lighting on WASH use and Gender-Based Violence (GBV) required a multi-disciplinary approach, combining OXFAM's practical implementing expertise with WEDC's research-oriented approach. The research showed how much more is needed for safe sanitation than just building latrines.
In 2016, the Technical Working Group (TWiG) of the national WaSH Cluster of South Sudan focused on water filter technologies in order to assess the suitability of the many filter products available for application in WaSH interventions within South Sudan. However, the TWiG didn’t analyse past disasters and water borne epidemics together with endemic diseases, and this paper wants to identify if there are and which are the criteria and information to be considered to choose the best filter (or other water treatm
