Hypothetical scenario exercises to improve planning and readiness for drinking water quality management during extreme weather events

摘要: Abstract Two hypothetical scenario exercises were designed and conducted to reflect the increasingly extreme weather-related challenges faced by water utilities as global climate changes. The first event was based on an flood scenario. second involved a combination of weather events, including wild forest fire (‘bushfire’) followed runoff due significant rainfall. For each scenario, panel diverse personnel from relevant agencies (e.g. health departments) formed utility associated regulatory body manage quality following simulated event. A larger audience participated asking questions contributing key insights. Participants confronted with unanticipated developments scenarios unfolded, introduced facilitator. presented information that may have challenged their conventional experiences regarding operational procedures in order identify limitations current procedures, assumptions, readily available information. process worked toward identification list specific lessons for At conclusion simulation facilitated discussion used establish value preparing them similar future events.
