Acknowledgements

This book represents the contributions of many individuals and organizations in the water supply and sanitation sector. The WSSCC Working Group on Promotion of Sanitation and its editors wish to thank sincerely the many who wrote articles, reviewed articles and reviewed the draft as a whole. Every attempt was made to consider seriously the inputs of every person and organization, to reach a consensus and to make revisions accordingly. Not every viewpoint expressed here is held by every member of the Working Group or the World Health Organization. In the end, the responsibility for errors and the inclusion of articles and points of view that may not be held by everyone in the sector is that of the editors alone. This responsibility we gladly accept.

Firstly we would like to thank the many authors who contributed articles, most of them without any financial remuneration. Without them, there would be no book.

Mary Falvey, Elizabeth Garfunkel and Jacqueline Sawyer provided editorial support.

Finally, there are not words strong enough to express the gratitude that the Working Group on Promotion of Sanitation and the Water Supply and Sanitation Collaborative Council feels for the generous financial support given to the Working Group. These donors stood behind the autonomous thinking of the group every step of the way and continuously offered words of support in addition to their financial contributions. We therefore give our heartfelt and deepest thanks to the Swedish International Development Cooperation Agency (Sida), the Swiss Development Cooperation (SDC) and the World Health Organization for their contributions.
