Submissions should not exceed 400 words, and must include your full name and address, plus a phone number for verification In our rapidly evolving world, Hong Kong must adapt and harness digital technology to manage its most precious resource –
water. At the moment, however, Hong Kong is lagging far behind other world cities when it comes to the task of digitally transforming water supply services.
The digital water approach integrates technology with water infrastructure, offering transformative benefits in managing water resources. However, transitioning to this system requires substantial upfront investment. Nonetheless, a cost-benefit analysis reveals the undeniable potential of this initiative.
Digital water systems enhance efficiency and sustainability in water management. Real-time data from smart sensors and meters allows predictive maintenance and early leak detection, reducing
water loss and operational costs. Over time, these efficiencies could outweigh the initial investment, proving the project’s financial viability. While the city has made a start in this regard, more needs to be done.
Secondly, digital water systems bolster resilience against climate change and urbanisation. Data analytics can predict potential vulnerabilities in our water network, enabling proactive measures to mitigate risks. Amid rising environmental uncertainties, the ability to maintain a stable
water supply is invaluable.
Furthermore, adopting digital water systems aligns with the global trend towards building smart cities. As Hong Kong aspires to be a leading
smart city, digitalising its water infrastructure could enhance the city’s competitiveness and attract international investments and partnerships in the technology and environmental sectors, boosting our economy.
Despite the upfront investment required, the benefits of digital water systems are compelling. For instance, implementing a smart water system in Hong Kong could help us lower the level of our city’s unmetered consumption, which accounts for a staggering 37 per cent of total water production. Reducing this water loss will translate into significant cost savings and better utilisation of our water resources.
