内容説明

This text shows how to set about the institutional development of the organizations necessary for monitoring and regulating rural water supplies. It discusses the new cost-effective approach to sanitary inspection of community water supplies and provides proposals for national guidelines for planning and implementing programmes of staff training. It reveals some of the critical technical, social and managerial errors which have been made in the past, describing the essential minimum of reliable methods for monitoring water quality. The authors provide proposals for developing countries which are now beginning to implement surveillance of drinking water quality.
