There  is  currently  limited  public  information  available  concerning  methods  for  the  selection  of appropriate  water  treatment  technologies  for  application  in  acute  phase  emergency  water  and sanitation  responses.  Considering  the  number  of  available  emergency  water  treatment  and  supply options,  it  is  speculated  that  a  framework  methodology  offering  guidance  in  the  form  of  a  selection process  would  offer  advantages.  This  process  would  relate  a  defined  set  of  emergency  factors  to  a selection  of  available  water  treatment  and  supply  options,  described  by  a  basic,  but  complete,  set of  technical  and  operational  characteristics.  It  is  suggested  that,  whilst  not  a  complete  process,  the proposed  framework  methodology  is  sufficient  to  lead  to  the  identification  and  selection  of appropriate  options  for  deployment.  Furthermore  the  support  of  critical  decision  making  by  a  logical framework,  could  help  shape  and  justify  the  actions  of  agencies  and  workers  in  the  field.
