• Description:
  This study assessed the vulnerability of coastal wastewater infrastructure to climate change risks. Projected impacts to both central sewer systems and on-site disposal systems from several climate change and coastal hazard scenarios were evaluated using a vulnerability framework. Climate and coastal hazard scenarios included: future sea-level rise (SLR), category 4 hurricane and a tsunami. The island of Oʻahu, Hawaiʻi was selected as the study area for this project to develop a methodology, planning tools and assess potential impacts that could be applied to other islands. The specific objectives of this project were to: Estimate wastewater asset exposure to sea-level rise and other coastal hazards; Estimate sensitivities of wastewater assets to exposures; Map system-wide exposure and sensitivity of wastewater infrastructures to sea-level rise and other coastal hazards on Oʻahu; Develop planning tools to project potential impacts of wastewater exposures and sensitivities to climate risks; Identify opportunities and challenges for adaptation.
