The human dimension of water safety plans: a critical review of literature and information gaps

A safe supply of drinking water is a cornerstone of public health and community well-being. Complacency among those responsible for the provision of safe drinking water (e. g., water suppliers, operators, and managers) has led to numerous and otherwise avoidable waterborne outbreaks. Water safety plans present a risk-based, proactive framework for water management, and when properly implemented, virtually eliminates the option for complacency. However, the uptake of water safety plans remain limited worldwide. This paper reports on the experiences of early water safety plan adopters and identifies a number of non-technical operational and human factors that have undermined previous efforts. Specifically, it identifies these factors as a gap in the water safety plan implementation literature and suggests incorporating the broader community in water safety planning through a community readiness approach. Assessing and building community readiness for water safety plans is suggested to be a critical pre-implementation step, and a potential tool for use by water suppliers and by policy makers.
