The report assesses resilience through source diversity, treatment reliability, energy exposure, monitoring capability, storage integration, operator competence, and the institutional arrangements that connect alternative assets with existing utility systems. What infrastructure and governance risks affect Global Water Systems? Global Water Systems face infrastructure risks from energy-intensive treatment, residuals management, aging networks, and fragmented delivery, alongside governance risks involving inconsistent regulation, tariff weakness, public acceptance, and unclear institutional accountability.
