CCTV News: According to the website of the Ministry of Water Resources, in order to ensure the safety of water supply in the Guangdong-Hong Kong-Macao Greater Bay Area urban agglomeration, under the unified deployment of the Ministry of Water Resources, the Pearl River Water Resources Committee will organize and implement the third "salty and lightweight" emergency water volume scheduling for the dry water period from 2024 to 2025. In recent days, the Pearl River Water Conservancy Committee has strengthened emergency duty and consultation and judgment, strengthened the implementation of reservoir dispatching instructions, tracked the evolution of water replenishment heads in real time, kept a close eye on the dynamics of the estuary, and guided Zhuhai and other places to seize the "window period" to seize the "window period" to snatch water storage.

Through this round of emergency dispatch of salt-pressing and light-filling, the reservoir groups of the "third line of defense" and "second line of defense" for the basin cascade water supply guarantee have accumulated a total of 765 million cubic meters of water downstream, and the average flow of Wuzhou Station on the main stream of the Xijiang River and Shijiao Station on the main stream of the Beijiang River increased to 2630 and 300 cubic meters per second, respectively. The maximum downward movement of the Xianjie boundary of the Modaomen Waterway in the Pearl River Delta is about 24 kilometers, effectively suppressing the salt tide of the Pearl River estuary. On January 15, Zhuhai’s main water intake outlet Zhuzhoutou Pump Station and Pinggang Pump Station were desirable throughout the day. It is expected that fresh water can still be extracted from the river channel in the next week. The water storage capacity of Zhuhai’s local reservoir groups was greatly supplemented, and the water supply safety of the Guangdong-Hong Kong-Macao Greater Bay Area urban agglomerations such as Macao and Zhuhai can be effectively guaranteed.

While ensuring water supply safety, the Pearl River Water Conservancy Commission continues to strengthen communication and coordination with power grid, shipping and other departments, taking into account the water needs of all parties. Rolling optimization of scheduling plans, improving energy utilization efficiency, strongly supports the operation safety of power grids, and improves the navigation capacity of the "golden waterway" in Xijiang. According to statistics from the shipping department, during the emergency water volume dispatching period, the capacity of the lock of the Xijiang Changzhou Water Conservancy Hub increased by nearly 90%, and the number of ships passing through the locks increased by more than 1,000 per day.

In the next step, the Pearl River Water Conservancy Committee will closely monitor changes in the rainwater and salty conditions, carry out the "four preparatory measures" in a rolling manner, and continue to build a "three lines of defense" for local, near-regional and far-regional water supply guarantee in the basin, make preparations for emergency water volume scheduling during the Spring Festival in advance, urge Zhuhai and other places to refine various water supply guarantee measures, strengthen the operation and maintenance of water supply pipelines, and make every effort to ensure the water supply safety of urban agglomerations in the Guangdong-Hong Kong-Macao Greater Bay Area such as Macao and Zhuhai.
