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.

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.

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.

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.

Frequently asked questions

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

You will be eligible for a full refund until two weeks after your payment date, or (for courses that have just launched) until two weeks after the first session of the course begins, whichever is later. You cannot receive a refund once you’ve earned a Course Certificate, even if you complete the course within the two-week refund period. See our full refund policy.

Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
