WEEK 1: Introduction to Household Water Treatment and
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 fecal contamination of drinking water are followed by an introduction to the concept of HWTS and the principal technologies. We discuss the global relevance of HWTS with focus on the post-2015 development agenda.
WEEK 2&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 2 focuses on sedimentation and different kinds of filtration. Week 3 focuses on heat, ultraviolet radiation, chemical disinfection. Specific modules are provided to cover safe storage and combined methods of water treatment.
WEEK 4: Implementation strategies for HWTS
During week 4 we analyze 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.
WEEK 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.
