When did Dongjiang water first supplied to Hong Kong?

To ensure stable water supply without relying on erratic rainfall, it was important to look for new sources of water. One of the ideas was to purchase and import water. During the drought in 1929, the government imported water and shipped water from Japan, Shanghai, Fuzhou and Zhuhai, in an attempt to solve the shortage of drinking water. While in 1956, the idea of acquiring Dongjiang water was also raised in the society. Since 1960, the government concluded several arrangements with the Guangdong authorities to provide Dongjiang water. Dongjiang, or the East River, is one of the rivers in Guangdong. Water is first extracted from the river at a point some 83 km north of Hong Kong, and pumped and discharges into the Shenzhen Reservoir. Water is then fed by pipelines across the border, and finally delivered along large pumping stations, pipes and tunnels to various parts of Hong Kong. Fresh water supply from Dongjiang is cheap and reliable, and the mode of provision of water to the Hong Kong has been changed. The annual Dongjiang water supply has been now almost 70-80% of Hong Kong's total demand starting since the late nineties.
