The objective of the survey within a water management plan is to identify the water systems and their key components. Identification is crucial because it allows for a comprehensive understanding of the various elements present in the plumbing system, including areas where Legionella bacteria may thrive. By identifying these components, such as water heaters, cooling towers, and storage tanks, it becomes possible to assess potential risks, implement necessary control measures, and develop strategies for monitoring and maintenance. This foundational step ensures that any further actions, such as treatment or monitoring protocols, are based on accurate and detailed information about the system in question.
