Water and Wastewater Utility Case Study   [open pdf - 1MB]

"The utility described in this case study is a large combined water and wastewater utility, located in the southeastern coastal United States. The utility was selected for the case study based on its demonstrated commitment to security and emergency preparedness, its ongoing coordination with local emergency response agencies, and its willingness to participate in this study and share its experiences. The utility's emergency management plans are largely driven by the threat of hurricanes with multiple contamination and threat scenarios that could impact critical customers and assets being served. The utility has adopted an all-hazards approach to manage and mitigate diverse risks and its emergency preparedness includes planning for response, recovery, and mitigation phases of an incident. For security reasons the name of the utility is not identified." "Decontamination is a critical component of the recovery phase of a water system contamination incident. Pre-planning and coordination for decontamination and recovery of a water system can minimize the impacts of a water contamination incident to public health and the environment. Most utilities are familiar with decontamination methods such as flushing and chlorination associated with returning a broken distribution line to service or a water system contaminated with a conventional, regulated contaminant. However, to decontaminate and return a water system to service following a non-conventional chemical, biological, or radiological contamination incident requires effective pre-planning, communication, and coordination."
