Since the implementation of the Water Security Plan for the Guangdong Hong Kong Macao Greater Bay Area, water conservancy departments at all levels have built a green ecological water network covering the entire area, and the water quality compliance rate of centralized drinking water sources has remained stable at 100%. This is what the reporter learned from the press conference on the 60th anniversary of the Dongshen Water Supply Project's effectiveness in supplying water to Hong Kong held by the Ministry of Water Resources on March 12th. The relevant person in charge of the Ministry of Water Resources stated that they will focus on building a green ecological water network in the Guangdong Hong Kong Macao Greater Bay Area. Water conservancy departments at all levels will take water related space control and water environment system governance as the starting point, deepen the normalization and standardization of the "four chaos" in rivers, lakes and reservoirs, strictly control the water and shoreline, create green ecological corridors, and promote the construction of thousands of miles of green roads and happy rivers and lakes. The person in charge introduced that in addition to the construction of a green ecological water network, water conservancy departments at all levels also focus on building an integrated high-quality water supply guarantee network, constructing a safe and reliable flood control and disaster reduction network, and constructing a modern intelligent supervision service network to provide water safety guarantees for the high-quality development of the Guangdong Hong Kong Macao Greater Bay Area. In terms of water supply guarantee, water conservancy departments at all levels are based on the interconnection of water supply sources and the potential improvement of water supply projects, promoting the completion and effectiveness of a series of projects such as the Datongxia Water Conservancy Hub and the Pearl River Delta Water Resources Allocation Project, and continuously optimizing the urban water supply structure in the Guangdong Hong Kong Macao Greater Bay Area. In terms of flood control and disaster reduction, water conservancy departments at all levels have focused on strengthening the construction of weak links in flood control and joint prevention and control. They have completed the construction of projects such as the management of the main stream of the Xijiang River in Guangdong and the Pujiang Flood Storage and Detention Area, successfully defended against multiple major floods and super typhoons, and ensured the flood control safety of the urban agglomeration in the Guangdong Hong Kong Macao Greater Bay Area. In addition, water conservancy departments at all levels focused on accelerating the construction of the digital twin water conservancy system in the Guangdong Hong Kong Macao Greater Bay Area, and built the "four pre" platform for flood and drought prevention in the the Pearl River, the digital twin Beijiang, and so on. At the same time, the establishment of the Guangdong Hong Kong Macao Greater Bay Area Water Security Key Laboratory by the Ministry of Water Resources has strengthened cooperation and exchanges with Hong Kong and Macao.
