Sanitation in Cold Climate Working Group 04a

Leading Image
This segment will address the unique challenges faced in cold regions, high-altitude areas, and places with significant seasonal changes. From freezing temperatures to limited water access, supply chain constraints, and infrastructure resilience, we aim to develop and exchange knowledge on sanitation solutions tailored to these conditions.

Why focus on sanitation systems and technology options?

Cold climates, including high-altitude and seasonal change regions, present unique challenges for sanitation systems, such as freezing temperatures, limited water access, supply chain difficulties, and infrastructure resilience issues. Traditional sanitation solutions often fail under these conditions, leading to health risks and environmental contamination.

This sub-theme within Working Group 4 focuses on developing tailored sanitation solutions that are resilient, cost-effective, and culturally appropriate for cold climates. It aims to bridge knowledge gaps and promote integrated technologies that address the entire sanitation chain, prioritizing resource-based sanitation whenever possible. These solutions must ensure health, hygiene, and environmental sustainability.

 

Objectives

This sub-theme aims to:

  • Develop and share knowledge on sanitation solutions for cold climates.
  • Facilitate informed decision-making with context-specific technology configurations.
  • Support effective implementation and operation through best practices and case studies.
  • Foster collaboration to develop sustainable sanitation solutions for cold climates.

 

Introducing the Leads of this Initiative

Judith Maréchal, specialised on WASH in cold climates, is working on establishing a network of expertise between polar and mountain regions. Currently based at the Civil and Water Engineering Department of ULaval, Québec, she has lived and worked in Norway, Nepal, and Greenland, and is also a member of the UArctic Thematic Network on Arctic WASH. Judith is striving to find solutions for cold and high-altitude regions that are both sustainable and culturally appropriate.

Tobias Ulbrich serves as a WASH Consultant at UNICEF WASH Hub in Copenhagen, where he focuses on Cold Climate Sanitation. Currently, he is evaluating a Container-Based Wastewater Treatment System (CBWTS) in Mongolia, with a view toward scaling it to other cold climate regions. Tobias brings extensive experience from his years in the WASH sector, including his role as WASH and Regional coordinator at BORDA.

Manual 2015

Composting is defined as the controlled biological decomposition and stabilization of organic substrates under a set of factors (e.g., temperature, moisture content, carbon-nitrogen ratio, degree of aeration, pH level, and physical structure of the raw materials), which allow development of thermophilic conditions as a result of biologically produced heat.
