The biggest block from HK’s largest water reservoir
- Waterfront boulevard, Sai Kung
- Open 24/7
This gigantic block is just one concrete block (referred to as a dolos) ….it took more than 7,000 dolosse - weighing 25 tonnes each - and 10 years to construct the High Island reservoir, the last and largest water reservoir built in Hong Kong.
Surprising scuba site!
The dolosse not only break the waves, they also provide excellent shelter for little fish. There are thousands of young yellowtail barracuda happily hiding between the concrete anchor blocks.
During the 1967 Hong Kong riots, the Chinese authorities briefly shut down the water tap….the HK government responded with the High Island reservoir. With a 280 million cubic metres storage capacity it practically doubled the available water storage capacity in the territory.
