Water Safety Plans (WSPs) are a management tool to identify and prioritize risks and implement appropriate control measures throughout the water supply chain, from catchment to consumer. WSPs have been implemented in over 90 countries; yet, costs, benefits and the enabling environment elements necessary for WSP implementation are under-studied.

Time for WSP implementation to achieve certification averaged 13 months. The main startup cost was staff time, averaging 16.2 full-time equivalent person-months. Additional costs, averaging €16,777, were for training staff, hiring consultants, purchasing equipment, and certifying WSPs. Benefits commonly reported included improved hazard control, treatment practices, record keeping, and client and health agency confidence.
