We are Elrha, a force for change in the humanitarian community. The research and innovation we support equips the humanitarian community with the knowledge of what works, so people affected by crises get the right help when they need it most.
Our purpose is clear: to empower the humanitarian community to improve humanitarian response. We make this happen by supporting and championing the outcomes of robust research and proven innovations.

This innovation addresses the inadequacies of current water treatment technologies, which are frequently not aligned with humanitarian objectives; resulting in unnecessarily expensive and sometimes ineffective relief.


Plate settling principles allow for relatively higher loading rates and consequentially a higher treated water production yield within a smaller footprint. By making the unit collapsible, setup times and transportation costs can also be reduced.
Added Value: Ultimately, larger volumes of water can be produced within SPHERE Standard water quality levels using a relatively low-cost and simple treatment process.

Innovation Phases Description:

  • Development: Development of a collapsible emergency water treatment system using inclined plate settling principles in partnership with relevant stakeholders (e.g. relief agencies, water treatment industry).
  • Implementation: Design, testing, validation, and implementation of the proposed technology in humanitarian relief contexts.


  • The principle deliverable is the Origami water treatment kit itself.
  • During the development of the water treatment system and its performance evaluation, a testing protocol for this kit will be established to aid in the development of other water treatment innovations.
  • Additionally, project findings will be disseminated through appropriate fora.
