Which activity is crucial for a water management plan concerning legacy plumbing systems?

Conducting regular risk assessments is crucial for a water management plan concerning legacy plumbing systems because these assessments help identify and evaluate potential sources of Legionella growth and transmission. Legacy plumbing systems often contain materials and designs that may pose higher risks for stagnation, temperature control issues, and biofilm buildup, all of which contribute to the proliferation of Legionella bacteria.

Regular risk assessments allow water management teams to proactively identify these risk areas, monitor system performance, and implement necessary controls or improvements before any potential outbreak or contamination occurs. By continuously assessing the water system, facilities can ensure that appropriate measures are in place to maintain water quality and safety, ultimately protecting public health. This proactive approach is essential for managing the unique challenges presented by older plumbing infrastructure.
