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?

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.

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.
