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?

Syllabus - What you will learn from this course
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.
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.
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.
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.

TOP REVIEWS FROM INTRODUCTION TO HOUSEHOLD WATER TREATMENT AND SAFE STORAGE
I so loved this course! I would like to thank coursera for granting me an opportunity to do this course! It is awesome I recommend that institutions offering water engineering courses should adapt it!
Very informative and practical course as water treatment is very useful and it is very nice to have knowledge about HWTS for a student.Teachers are very knowledgeful and interactive in this course.
A very well organised course. Dr. Rick Johnston is an excellent mentor to have! Wish him all the best. Highly recommended for Civil Engineering/ Environmental Study backgrounds.
This course is very interesting to me and I really like the presentations and the ability to study at will, my knowledge on water treatment have been upgraded. Thank You
