Linking Health Concepts in the Assessment and Evaluation of Water Distribution Systems

Abstract

The concept of health is not only a specific criterion for evaluation of water quality delivered by a distribution system but also a suitable paradigm for overall functioning of the hydraulic and structural components of the system. This article views health, despite its complexities, as the only criterion with suitable depth and breadth to allow a holistic assessment of system performance. Although many decisions relating to the planning and design of water distribution systems do implicitly consider human health, engineers and planners seldom explicitly adopt a “health mindset” overall and, thus, miss the richness and possibilities of a health framework for a wider range of system evaluations, considerations, and trade-offs. This article argues why a breakdown in a healthy system will so frequently result in stresses experienced by humans and briefly reviews the concepts of human health and system health and provides specific examples of a significant interaction between the two.
