Project Significance

The Pearl River Delta Water Resources Allocation Project is a major national water conservancy project and national water network backbone project deployed by the CPC Central Committee and the State Council, an important part of Guangdong's "five vertical and five horizontal" water resources allocation backbone network, and one of the 172 major water conservancy projects for water-saving and water supply deployed by the State Council. The project has a total length of 113.1 km of water transmission lines and a total planned investment of about RMB 35.4 billion . Since the comprehensive start of construction on May 6, 2019, it has taken 4 years and 8 months to basically complete. After completion and opening to water, it has been able to divert water from the Xijiang River system to the eastern part of the Pearl River Delta, with an annual water supply of 1.708 billion cubic meters. It is the largest water resource allocation project in Guangdong that has been built, with the longest water transmission line and the widest water receiving area.The Pearl River Delta Water Resources Allocation Project starts from Liyuzhou, Shunde, the main stream of the West River in the west, crosses Shiziyang, and ends at Shenzhen Gongming Reservoir in the east, with a total length of 113.2 km. The implementation of the the Pearl River Delta Water Resources Allocation Project aims to solve the problem of water shortage in Shenzhen, Dongguan, Guangzhou Nansha and other places, effectively change the previous single water supply pattern in the water receiving areas, and improve the city's water supply security and emergency support capacity, It plays an important role in ensuring urban water supply security and economic and social development, and will also provide strategic support for the development of the Guangdong Hong Kong Macao Greater Bay Area. The Pearl River Delta Water Resources Allocation Project can effectively solve the problem of water shortage in life and production in Guangzhou, Shenzhen, Dongguan and other places, provide emergency standby water sources for Hong Kong, Guangzhou Panyu, Foshan Shunde and other places, gradually return ecological water to the Dongjiang River basin, and further ensure the water supply safety and ecological security of Guangdong Hong Kong Macao Bay Area.珠江三角洲水资源配置工程是党中央、国务院部署的国家重大水利工程、国家水网骨干工程,是广东“五纵五横”水资源配置骨干网络的重要组成部分,是国务院部署的172项节水供水重大水利工程之一,工程输水线路总长113.1千米,计划总投资约354亿元。自2019年5月6日全面开工建设以来,历时4年8个月基本完工,建成通水后实现从西江水系向珠三角东部引水,年供水量达17.08亿立方米,是广东已建成投资规模最大、输水线路最长、受水区域最广的水资源配置工程。 珠江三角洲水资源配置工程西起西江干流顺德鲤鱼洲,穿越狮子洋,东至深圳公明水库,全长113.2公里,实施珠江三角洲水资源配置工程,旨在解决深圳、东莞、广州南沙等地发展缺水问题的同时,有效改变以往受水区单一供水格局,提高城市的供水安全性和应急保障能力,对保障城市供水安全和经济社会发展具有重要作用,同时也将对粤港澳大湾区发展提供战略支撑。珠江三角洲水资源配置工程可有效解决广州、深圳、东莞等地生活生产缺水问题,并为香港、广州番禺、佛山顺德等地提供应急备用水源,可逐步退还东江流域生态用水,进一步保障粤港澳大湾区供水安全、生态安全。
