Advisory Committee on Water Supplies begins visit to Dongjiang Water Supply System in Guangdong (with photos)
******************************************************************************************
The following is issued on behalf of the Advisory Committee on Water Supplies:
 
     A delegation of the Advisory Committee on Water Supplies (ACWS) departed for Guangdong Province this morning (November 4) to begin a two-day visit to the Dongjiang (DJ) Water Supply System and learn about the latest developments of matters in relation to the DJ water supplied to Hong Kong.
      
     This morning, the delegation visited the Gaoxinsha Reservoir in Nansha, Guangzhou, to see the Pearl River Delta Water Resources Allocation Project. The project, commissioned in 2024, diverts water from the Xijiang River to the eastern part of the Pearl River Delta, providing a new water source for Nansha of Guangzhou, Shenzhen, Dongguan and other regions, and enabling the DJ and Xijiang Rivers to complement each other. The Committee was pleased to learn that the project will help relieve the demand for DJ water in the cities along the DJ River's course, and will also provide an emergency backup source of water for Hong Kong, thereby enhancing the water security of the Guangdong-Hong Kong-Macao Greater Bay Area and optimising the region's water resources allocation capabilities.
      
     In the afternoon, the delegation proceeded to the Greenway in Huizhou, which runs along the banks of the DJ River, to observe the quality of the DJ water supplied to Hong Kong at a close distance and to receive briefings from the relevant Guangdong authorities on the water quality protection measures. The delegation then visited the DJ River Basin Water Quantity and Quality Monitoring and Control Centre in Huizhou to learn how the Centre leverages an advanced intelligent platform for real-time control of water supply facility operations as well as close monitoring of water quality along its course. The Committee considered that the intelligent platform adopted by the Centre can effectively enhance operational efficiency and incident response capabilities, thereby further safeguarding the stable supply and water quality of the DJ water supplied to Hong Kong.
      
     The delegation will continue its visit tomorrow (November 5) to inspect the intake point of the DJ water supplied to Hong Kong in Dongguan and various major operation points downstream, and to meet with local government officials. The visit will conclude tomorrow afternoon, with the delegation returning to Hong Kong thereafter.
      
     The terms of reference of the ACWS are to advise the Government of the Hong Kong Special Administrative Region through the Director of Water Supplies on matters relating to water supplies, including water resources, network management, regulation and control of inside services, water conservation and other operational matters. Its membership comprises academics, green advocates, professionals, representatives from the trade, and officials from related government departments and bureaux.
