珠澳“供水心脏”扩容2.6倍，抢淡蓄库能力实现历史性跨越

Core Upgrade and Historical Expansion of Water Supply - The Pinggang Pump Station, a critical hub for the water supply system between Zhuhai and Macau, has increased its water extraction capacity from 1.4 million cubic meters per day to 3.6 million cubic meters per day, representing a 2.6-fold increase [1][2] - This expansion addresses the growing demand for water resources due to periodic saline tides and unexpected water pollution risks, which have put pressure on water security in the region [2] Technical and Safety Enhancements - The second phase of the Pinggang Pump Station introduces three unique technical and safety measures, creating a robust water security barrier for the Greater Bay Area [3] - The first measure is a pre-treatment system that includes a powdered activated carbon injection system and sodium hypochlorite injection system, which helps reduce harmful substances in the water [3] - The second measure involves a high redundancy and flexible scheduling system with 12 water pumps, ensuring that overall water extraction capacity remains unaffected even during maintenance [3] - The third measure integrates the project into a larger framework of interconnected water sources, enhancing the resilience of the water supply system [3][4] Strategic Location and Economic Feasibility - The decision to expand at Pinggang rather than upstream at Zhuzhoutou was based on economic and practical considerations, as Pinggang offers better infrastructure and faster implementation [5] - The existing infrastructure at Pinggang allows for a more efficient water supply network, with the ability to transport 2 million cubic meters per day to downstream facilities [5] Long-term Water Supply Commitment - Since the establishment of the water supply to Macau, Zhuhai has provided a total of 2.1 billion cubic meters of water to Macau in the past 26 years, which is three times the amount supplied in the previous 40 years [5] - The Pinggang Pump Station's second phase enhances the stability and reliability of water supply, supporting the long-term prosperity and stability of Macau and deepening cooperation between Zhuhai and Macau [6]
