Acknowledgements

These guidelines have been considerably updated and modified from the first editions and
there have been contributions from Brian Clarke (University of Surrey).

The original development of the Water Packs was made possible with the generosity and professional
skill of the University of Surrey and the Public Health Engineering section of Imperial College,
London. Since then, active development and evolution of the water kits has continued, based on field
experience and with continued input from the University of Surrey and others.
