Hong Kong possesses world-class, highly reliable infrastructure. The electricity supply, managed by CLP Power and HK Electric, is exceptionally stable with virtually no blackouts. Given the lack of natural lakes and rivers, the territory imports roughly 70-80% of its fresh water from the Dongjiang River in neighboring Guangdong province, supplemented by local reservoirs and seawater flushing systems.
Telecommunications infrastructure is top-tier, boasting some of the highest broadband internet speeds and deepest fiber-optic penetration globally, alongside comprehensive 5G cellular coverage. The city also operates sophisticated waste management, sewage treatment, and flood-prevention systems, including massive underground stormwater drainage tunnels.
