Workshop on emergency sanitation in Delft, the Netherlands, June 2012

Emergency camp’s sanitation infrastructure is often inadequate and the risks to people’s health become extreme. Governments, NGOs and Humanitarian organisations are fully aware of these problems and the fact that the basic pit latrine design has not been improved upon in decades which aggravated those problems even more.

This is especially applicable for camps packed with tens of thousands of people, be it in refugee situations or after natural disasters. Thus, a consortium of organisations (The Netherlands Red Cross, WASTE, OXFAM GB, the IFRC, and UNESCO-IHE) brought together for three days private manufacturers, humanitarian organizations, and researchers to foster the development of sanitation designs and systems to particularily tackle the aforementioned problems.


Introduction of the Emergency Sanitation Workshop in Delft, the Netherlands.     

Photos from the workshop

Structure of the workshop

The workshop itself was structured according to the three links of the sanitation chain:

  • Day 1: Raised latrines
  • Day 2: Desludging equipment
  • Day 3: disposal and treatment

Each of the days consisted of a problem definition of the specific topics, a variety of pitch presentations, where suppliers of sanitation equipment presented their solution to the problem and an intensive workshop time slot where the participants were asked to brainstorm and design a sanitation solution for a given scenario and give input to a list of specifcations that will be used in the design and development of (post-) emergency sanitation kits. The list of specifications is part of the outcome of a project funded by the Dutch government.

Furthermore, we opened a discussion in the SuSanA discussion forum, where we would like to give the participants the opportunity to give feedback regarding the workshop and also to give the rest of the SuSanA community the chance to leave a comment reagrding workshop or documentation.

The minutes of the workshop will be available soon.
