À propos de ce cours : It is well known that water treatment at the household level can lead to dramatic improvements in drinking water quality. But does Household Water Treatment and Safe Storage (HWTS) also have global relevance? What are the potential treatment solutions and how do they function? Is there a standard strategy for successful HWTS implementation, or can we identify key components which make programs more likely to succeed? In this course you will learn about the most important water treatment methods at household level, successful implementation strategies and about assessing the impact of HWTS. MOOC SERIES “SANITATION, WATER AND SOLID WASTE FOR DEVELOPMENT” : This course is one of four in the series “Sanitation, Water and Solid Waste for Development". FRANçAIS: Dans ce MOOC, vous allez apprendre les plus importantes méthodes de traitement de l'eau au niveau des ménages, les stratégies pour une mise en œuvre réussie et l’évaluation de l’impact du traitement et stockage sûr de l'eau à domicile. ESPAñOL: Aprende acerca de los métodos más importantes de tratamiento de agua a nivel domiciliario, de estrategias de implementación eficientes y de la evaluación del impacto del tratamiento doméstico y almacenamiento seguro del agua.

Les destinataires de ce cours : This course is an introduction – the only course requirement is an interest in drinking water quality.

Programme de cours

SEMAINE 1

Introduction to HWTS

The course begins with a review of the public health impacts of unsafe drinking water. We define physical, chemical, and microbial aspects of drinking water quality and present the major classes of pathogens. Information about pathways for faecal contamination of drinking water are followed by an introduction to the concept of HWTS and the principal technologies.

SEMAINE 3

HWTS treatment options

During week 2 and 3 we focus on potential treatment methods. We refer first to the standards of safe drinking water and improved drinking water. Week 3 focuses on heat, ultraviolet radiation, chemical disinfection. Specific modules are provided to cover safe storage and combined methods of water treatment.

SEMAINE 4

Implementation strategies for HWTS

During week 4 we analyse different approaches that have been successfully applied. We highlight key components which make programs more likely to succeed. We ask the questions, what is required that the most vulnerable populations use HWTS correctly and consistently over the long-term? In separate modules we consider the special case of HWTS in emergency response and provide information about the role of government bodies.

SEMAINE 5

Monitoring and Evaluating HWTS

During the last week, we present different approaches for monitoring and evaluating HWTS. Case studies and guest lecturers, we highlight several key challenges, including the need for consistent use and field-robust measurements. The course ends with a wrap-up module, which serves as preparation for the final exam.
