Water utilities’ supply systems are vulnerable to several climate-related hazards, including droughts, floods and cyclones.
This paper proposes a generalist framework for conducting multi-hazard risk assessments of water supply systems, using customer disruption days as a common metric for comparing different hazards impacts. providing a a means to quantify the impact of present and future climate extremes on the national water supply network, using the case of Jamaica.
The paper further consider the scope for applicability to other environmental hazards and concluding the report advances our understanding of the impact of multi-hazard risks on water supply infrastructure. By providing a platform for
(a) promoting the need for investment in climate adaptation projects in the water sector and
(b) prioritizing strategic adaptation options across asset protection and drought mitigation projects, to enhance water supply system resilience in the face of a changing climate
