To ensure our ability to adapt to the worse-than-expected scenarios, a host of backup measures have been formulated. These include building up more desalination capacities, expanding our reservoir capacity and catchment, reactivating mothballed water treatment works and increasing Dongjiang water supply. If the future conditions deviate from our present projections, we can implement appropriate backup measures as necessary. We will conduct regular review of the “Strategy 2019” and update it as needed to make appropriate and timely responses to changes arising from water demand, the effect of climate change on the local yield, as well as the cost-effectiveness, technological development, reliability and environmental impact of various water resources. 至二零四零年之全年食水需求推算 Annual Fresh Water Demand Projection by 2040 水務署 二零二二至二三年年報 WSD Annual Report 2022/23 18 Scale up 升 級 開 拓
