Recent systematic reviews have highlighted a paucity of rigorous evidence to guide water, sanitation and hygiene (WASH) interventions in humanitarian crises. In June 2017, the Research for Health in Humanitarian Crises (R2HC) programme of Elrha, convened a meeting of representatives from international response agencies, research institutions and donor organisations active in the field of humanitarian WASH to identify research priorities, discuss challenges conducting research and to establish next steps.

Simple improvements for emergency batch water treatment

Publication year
2007
Country

Batch water treatment consists of the intermittent use of settling tanks for water clarification, and is a common treatment practice during emergency relief efforts. This article presents simple improvements to coagulant dosing and water quality based on experience gained in the aftermath of the 2005 South Asian earthquake.

"Appropriate Technologies" for Drinking Water Supply in Developing Countries

Publication year

Emergency type

In  order  to  ensure  maximum  consumer  benefits  (e.g.  public  health,  livelihood),  drinking  water  supply  technologies  in  developing  countries  should  be  adopted  taking  into  consideration  locally  available  skills,  resources  as  well  as  cultural  and  environmental  settings.  This  paper  presents  case-studies  from  several  developing  countries  in  different  geographical  regions  of  water  supply  projects  utilizing  methods  ranging  from  biological  treatment  offered  slow  sand  filtration  systems  to  chemically-ass

Coagulant-based Emergency Water Treatment

Emergency  water  treatment  approaches  relying  on  coagulation  vary  from  centralised  modular  and  portable  ‘‘kits’’  to  ‘‘point-of-use’’  or  ‘‘household’’  interventions.  Typical  coagulation  practice  in  emergencies  is  reviewed  in  view  of  field  constraints  (e.g.equipment  and  resources)  and  contrasted  with  underlying  theory  and  conventional  water  treatment  procedures.  Examples  of  coagulation  in  emergencies  are  also  presented  based  on  documented  field  experiences  alongside  the  discussion  of  other  relevan

The supply of adequate amounts of safe water for drinking and hygiene during natural disasters or armed conflict can be compromised and is one of the priorities in public health interventions to prevent the spread of disease. When surface waters are the only viable source, emergency water treatment kits are usually deployed by relief agencies for the supply of water. One option is the Oxfam Field Up‐flow ‘Clarifier’ Kit, which was designed to treat raw waters with high turbidities to adequate levels [i.e. <5 nephelometric turbidity units (NTU)] and at a relatively high yield (i.e.
