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.

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.

This week we looked at a range

of different ways that HWTS interventions can be implemented.

We started by considering approaches that seek to

either maximize profits, or social goods, like reducing disease,

and how social businesses combine some of the

aspects of those two approaches. But whichever

approach is taken, basic questions of demand, supply,

and financing need to be taken into consideration.

Next, we looked at targeted approaches where by integrating with other kinds

of interventions, it's more possible to reach the vulnerable people efficiently.

So, the examples we looked at here were in schools, through education programs.

And with the health sector, through either maternal and

child health initiatives, like this antenatal care project in Malawi,

or HIV AIDS management programs.

And in both cases there are, synergies that can be had.

Both interventions can gain if for example,

in the health care example, it was shown

that people sought more health care when

the program was tied with an HWTS intervention.

And at the same time, uptake rates were very high.

And there are a variety of reason for this.

It could be that the people are particularly

vulnerable and willing to adopt a new behavior.

Could be that the communication channels are

well-trusted whether its teachers or healthcare workers.

But, for whatever reason, there's evidence that this kind of

integrated approach can yield benefits for both interventions.

We next considered a very specific type of

targeting vulnerable populations, that of HWTS in emergencies.

We had a guest lecture from Dr. Daniele Lantagne at Tufts University in the USA

and she talked about some of the

experiences evaluating HWTS in a range of countries.

And one of the key things from her findings

were that preparation is key in advance of the emergency.

And also that you have to have that combination

of unsafe water and effective treatment and consistent and

effective use in order to realize health gains and

we'll come back to that message in next week's modules.

Finally, we looked at some of the different

roles that government bodes can play in HWTS interventions.

Different kinds of government bodies at different levels.

And took as a frame work, the

human rights consideration of, responsibilities of governments

to respect, to protect and to fulfill

rights, and in particular, with relation to HWTS.

We saw how that fulfilling responsibility could

involve facilitation through information collecting and coordination.

Could also involve promotion and evaluation of technologies.

And finally, provision of services, especially targeting the vulnerable

people who have no other ways to access safe water.

We then gave an example of how national plans and strategies can

bring together these different roles of government into a coherent package.
