The Pearl River Committee discusses the deployment of Typhoon "Qiangpi" defense and water supply guarantee work during dry periods

China News Service, Guangzhou, October 22 (Reporter Wang Jian) ​​The Pearl River Water Conservancy Commission of the Ministry of Water Resources (hereinafter referred to as the "Pearl River Commission") held a special meeting on the 22nd to analyze and judge the development trend of typhoon "Qiangpi" and the rainwater situation in the basin, and arrange and deploy key tasks for recent flood and drought disaster prevention.

According to the consultation report, at 10:00 on October 22, Typhoon No. 30 "Qiangpi" this year was located in the ocean southeast of Taiwan. It will move into the southern part of the East China Sea on the night of the 23rd and then turn to move northward. It is predicted that in the next week, the Pearl River Basin will mainly experience light to moderate rain, and the water potential of major rivers will be stable and controllable.

As of October 22, the effective water storage capacity of Longtan and other key reservoirs in the upper reaches of the Xijiang River is 16.65 billion cubic meters, with an effective water storage rate of 77%; the three major reservoirs such as Dongjiang Xinfengjiang have an effective water storage capacity of 7.03 billion cubic meters, with an effective water storage rate of 87%. This can effectively guarantee the water supply security of the Guangdong-Hong Kong-Macao Greater Bay Area urban agglomeration, the APEC meeting, and the water demand of the Pinglu Canal.

The consultation required that we should pay close attention to the movement path and development changes of Typhoon "Qiangpi", carry out rainwater monitoring, forecasting and early warning on a rolling basis, and never relax in various defensive measures to ensure the safety of flood control in the river basin. It is necessary to use the "Four Predictions" platform to continuously deduce the impact of salt tides, optimize dispatch plans in real time, scientifically and meticulously implement water storage dispatch for key reservoirs such as Longtan, Baise, and Datengxia, guide Zhuhai's local reservoirs to store water and replenish their reservoirs, and build a solid "three lines of defense" to ensure local, near- and remote water supply in the basin.

At the same time, it is necessary to comprehensively consider the water needs of water supply, ecology, power generation, shipping and other parties, implement multi-objective coordinated dispatch, and make careful use of "each storage capacity" to ensure that the comprehensive benefits of water resources are fully utilized. It is necessary to urge and guide Zhuhai and other places to strengthen the inspection, repair and maintenance of water pumping stations, water supply pipelines and facilities, refine and improve emergency plans, be prepared to respond to emergencies, and maintain water safety defense lines.

In addition, it is necessary to do a good job in "suppressing salty water and replenishing fresh water" water volume dispatch, publicizing the effectiveness of water supply guarantee, and creating a good public opinion atmosphere.
