Economical Issues(Peter Wildere, 2002).

It becomes evident that the capacity of the global money market would not be sufficient to cover the need for investment capital for centralized system

The rehabilitation cost for the piping system in Germany is estimated to be in the range of 100 billion euros

The cost of the installation of the pipe system is almost one order of magnitude higher than the cost of building the treatment facilities

Role of policy


Discrimination by gender, social and cultural aspects, handicap needs to be overcome by participatory approach.

We should give access to adequate education, income and health care to all the people.


Improving Sustainable Water and Sanitation systems in Sahel

Region in Africa: Case of Burkina Faso

JST-JICA Research Project (2009-2014)


Final goal of the Project

Contributing to the achievement

of the Millennium Development

Goals (MDGs) in water and sanitation

(1)Research(2)Capacity development(3)Socialization


Summary

The role of technology: – Technologies and social,

institutional system should adapt to the social conditions.

– Water technology should be a resource recovery technology, not a treatment technology.


Summary The role of policy :

– Discrimination by gender, social and cultural aspects, handicap needs to be overcome by participatory approach.

– We should give access to adequate education, income and health care to all the people, and consider how to include the poorest of the poor.

– We should have the long term perspectives to how to adapt the change in developing countries from the society with one dollar per capita per day of GDP to the society with ten dollar and then a hundred dollar per capita per day.


Summary

The role of Science: – The speed of the technological,

economical and demographical changes taking in place in the current worlds must be slowed down to have a time for the scientific evaluation of these solutions.
