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.

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!

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.\n\nThank You

The numerical section was little tough need to practice with some examples . Should be given self assessing questions to solve and get more clear idea of numericals
由 TX 提供Aug 15, 2019
While I found the first weeks very interesting, the charm went down after, talking about charts that might help NGO's and researchers, not that much for learners.
由 CG 提供Sep 2, 2018
The information provided is spectacular and extremely interesting! The size of videos though should be smaller, maximum 15 minutes as they become a bit tiring.
由 AP 提供Jul 12, 2017
Extremely Helpful and Exceptionally well designed course. Thanks a lot to all the personnel and Coursera for bringing this course/
