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.

Poor surface water drainage can pose health risks by supporting the development of vector-borne diseases such as malaria or cholera. It can also pose accessibility problems by making it difficult for people and humanitarian services to make their way through a camp and maintain essential water and sanitation services.

Building on the findings of our Gap Analysis, and the Problem Exploration Report on Surface Water Drainage, two core problems stood out:

  • While surface water drainage solutions exist, the information is scattered across multiple sources and it is not always clear which solutions are best to use in which context.
  • Most of the existing solutions come from the development sector and are therefore resource-intensive and impractical in a humanitarian crisis.

We have also produced a Challenge Candidate List, which provides a summary of the key challenges presented in the Problem Exploration Report
on Surface Water Drainage.

We have prioritised innovations looking to address these particular surface water drainage challenges.

We have prioritised innovations looking to:

  1. Develop guidance to help field practitioners decide between existing drainage solutions in an emergency;
  2. Develop affordable and effective solutions to improve surface water drainage in an emergency.

WASH in Emergencies Problem Exploration Report: Surface Water Drainage

Globally, waterborne diseases and sanitation-related infections are both major contributors to public healthcare burdens and mortality. Effective drainage reduces breeding grounds for vectors (such as mosquitoes) and reduces the creation of muddy stagnant pools that harbour dangerous pathogens which cause a wide range of diseases. The findings of this report suggest that a paradigm shift that takes into account the need for long-term, tailored drainage solutions in emergency situations is required.
