Developing knowledge and capacity in water and sanitation
Historically, global control of drinking water has relied upon infrequent testing of selected water quality parameters at specified points within a water supply. Weaknesses identified by the World Health Organization (WHO) in this approach have resulted in a fundamental change noted in the revised, third edition of the WHO Guidelines for Drinking Water Quality, 2004. The change involves the development of quality assurance processes known as Water Safety Plans (WSPs) founded upon the HACCP principles used in the food industry.
Water Safety Plans - Books 1 and 2, document state of the art research designed to complement the advances being made in the global water quality sector. Book 1 presents guidelines for implementing WSPs in developing countries. Book 2 gives further detail on supporting programmes. Together they provide essential reading for water utility managers, helping them to assess, identify and manage water quality risk in their piped water supplies, as well as individuals and organizations representing vulnerable groups and suggesting methods for improving monitoring and management of water quality in low socio-economic areas.
Evidence for these books is drawn from three years of research undertaken in Uganda and India funded by the Department for International Development (DFID).
