China News Agency, Guangzhou, March 3 (Source: Wu Yirong, Wang Fengen) The Pearl River Water Conservancy Commission (hereinafter referred to as the “Pearl River Commission”) notified on the 3rd that the Pearl River Commission has recently completed the 2019-2020 Pearl River dry season water dispatching and achieved the 16th consecutive year of guarantee. Water supply security in Macau.
In order to ensure the safety of water supply in the Guangdong, Hong Kong, and Macau Greater Bay Areas such as Macau and Zhuhai, the Pearl River Commission officially launched the Pearl River dry season water dispatch in 2019-2020 in October 2019 and ended on February 29, 2020. During the dispatch period, a total of 138 million cubic meters of water were supplied to the main urban areas of Macao and Zhuhai, of which 95.9 million cubic meters were provided to the main urban area of Zhuhai and 41.7 million cubic meters were provided to Macau. This ensures the safety of water supply in Macao, Zhuhai and other places for the 16th consecutive year, while ensuring that The construction of the Datengxia Water Conservancy Project during the river closure period was safe, and the win-win situation of water supply, power generation, shipping, and ecology was achieved again.
It is reported that in July 2019, the Pearl River Commission prepared the relevant work on the implementation of the Pearl River dry season water dispatch implementation plan, and based on the forecast of rainwater dryness during the dry season and strong salty tide activity, it organized the early storage of the Xijiang Backbone Reservoir and Zhuhai Local Reservoir.
At the end of 2019, the rainfall in the Pearl River was severely low. From November to December, the rainfall in the Xijiang River Basin was nearly 60% lower than the same period last year. In December, the natural water from the Wuzhou Station in Xijiang was as low as 1380 cubic meters per second, especially in the early part of the 20th anniversary celebration of Macau ’s return. The impact was strong. It was difficult to get water in Zhuhai, Zhongshan and other places, and the water supply situation was severe. The Pearl River Commission optimized and adjusted the scheduling plan in time, carried out joint water replenishment scheduling for the Northwest River backbone reservoir, increased the outflow of Longtan, Feilaixia, and Changzhou water conservancy hubs, successfully restrained the estuary salty tide, and increased water intakes in Zhuhai and Zhongshan. The probability of thinning has effectively alleviated the contradiction in water supply.
After the outbreak of the new crown pneumonia, the Zhujiang Committee, while doing a good job in the prevention and control of the epidemic, has not spared no effort to ensure the security of water supply in Macao and Zhuhai, Zhongshan and other Greater Bay Areas, creating a good environment for the prevention and control of the epidemic. At present, the water from Wuzhou Hydrological Station is relatively good, the local reservoir in Zhuhai has sufficient water reserves, and the impact of salty tide has been significantly weakened. The safety of water supply in the Greater Bay Area such as Macau and Zhuhai can be effectively guaranteed. (Finish)
