Following the recommended two-pronged approach under the Strategy 2019 by containing the growth of fresh water demand and building resilience of the fresh water supply, the future fresh water resources in Hong Kong will comprise the following.
- Dongjiang water with water supply ceiling of 820 mcm per annum (~ 60% - 80% depending on the amount of local yield)
- Local yield (~ 15% - 35%)
- Desalinated water up to 50 mcm per annum (~ 5%)
Besides, while the above fresh water resources will account for about 75% of the total water consumption in Hong Kong, the lower grade water (namely seawater and recycled water) for non-potable uses will account for the remaining 25% in the Strategy 2019.
