On August 1, 1883, the Yangshupu Water Plant was completed and officially started supplying water to the public, marking China's first modern water plant and bringing tap water into urban life. Today, this old factory celebrates its 140th anniversary and embarks on a new journey.
Located on the southern bank of the Huangpu River, the Yangshupu Water Plant covers an area of 129,000 square meters, and its largest footprint was once as large as 259,000 square meters, making it the earliest and largest modern water plant in Shanghai.
With the birth of New China, starting from 1949, the Shanghai Municipal Government merged five separate water supply enterprises into the Shanghai Water Company through acquisitions, requisitions, management, and consolidation, achieving unified operation of the city's water supply enterprises in 1955. To improve water conditions for the people and alleviate the frequent occurrence of waterborne infections, the city government allocated funds to build water supply stations in shantytowns, charging half the price for water. By 1956, there were 1,865 water supply stations across the city, providing tap water to 1.3 million residents in shantytowns.
In the late 1980s, the water plant initiated self-renewal, conducting in-depth renovations and equipment expansion for sedimentation tanks, upgrading to an automatic sludge drainage system, and entering the realm of automation system transformation. These improvements ensured safer equipment, more reliable operation, and better water quality. Beyond the physical infrastructure, the water plant's industrial facilities, equipment, and processes were preserved and showcased. Within the plant, the Shanghai Tap Water Science and Technology Museum used informative methods to offer a more direct understanding of the production story behind the heritage-protected architecture, revealing lesser-known aspects of urban water supply endeavors.
Today, strolling along the Yangpu riverside, the well-preserved and distinctive Gothic-style castle architecture of the Yangshupu Water Plant stands as a unique landmark. Designed by British engineer J.W. Hart, the main building of the water plant takes the form of a traditional British castle, with a rust-red hue and twin castle-like wings flanking the main structure's east and west sides. Load-bearing walls are made of plain bricks adorned with red brick belts, and crenellations crown the top of the surrounding walls. Cement lines accentuate the crenellations, window frames, and belts. The intersections of the walls are shaped like cement cornerstones, reminiscent of a medieval castle.
As Yangpu Riverside transitions from an "industrial rust belt" to a "showcase of life," integrating the concept of a "people's city" into water production becomes a question for the Yangshupu Water Plant.
Through collaborative and coordinated efforts, the water plant has established a city water supply system that prioritizes water conservation, safety, quality, intelligence, and efficiency, aiming to match the water quality standards of developed countries worldwide. The deep treatment and renovation projects are carried out in stages, preserving the appearance of the national heritage-protected site while incorporating modern engineering. This approach preserves the distinctive elements of industrial civilization and serves as a model case for the repair and modernization of industrial heritage in the municipal water sector.
In the digital age, the Yangshupu Water Plant embraced a data-driven mindset, utilizing digital technology to accelerate the creation of a new water management ecosystem characterized by real-time sensing, scientific decision-making, proactive service, and intelligent supervision. From automation to digitalization, the foundation of a digital twin water plant is taking shape, driving the acceleration of intelligent water applications.
"We are currently undergoing a new round of plant upgrades to enhance deep treatment processes, with the completion expected by the end of 2024. By then, water quality will be significantly improved once again, with a smoother taste," said the current plant manager, Song Yu, to the reporter. "Providing better water for the people remains our unchanging mission and purpose."
