Suggestions for communication activities in developing new and ongoing water programs are offered in this handbook. It is one in a series of UNICEF publications that aim to inform a variety of audiences on life quality concerns. Specific objectives in this guide focus on providing information and education in the use, transportation, storage, and processing of water. Topic areas which address water quality needs include: (1) the concept of safe water (discussing the meanings given to the categories of clean and unclean water and the importance of understanding theories of disease transmission); (2) audience identification and analysis (identifying the types of water that are of interest to different community groups and suggesting ways of improving water supply and sanitation); and (3) audiences outside the community (emphasizing the need for co-operation and assistance from engineers, technicians, and business people). A color coded, fold-out data checklist for program planning (listing the types of required data and indicating the implications of program design) conclude the document. (ML)
