The Intelligent Transformation and System Awakening of Water Supply and Drainage Network

Pain point hit: “Systemic imbalance” of underground pipeline network

As the “inner lining” of urban infrastructure, the current state of the water supply and drainage pipeline network often contrasts sharply with the shiny urban surface. Currently, although the scale of China’s urban water supply and drainage pipe network has jumped to the top in the world, the overall efficiency still faces severe challenges of “systematic decline and collaborative failure”:

• 1. “Blood loss” and “secondary pollution” of the water supply network: A large number of water supply pipelines that have exceeded their service life are severely corroded, which not only leads to a leakage rate of up to 15% -20%, causing huge waste of precious water resources, but also easily causes secondary pollution problems such as “red water” and “yellow water”, directly threatening the drinking water safety of residents.
• 2. “Obstruction” and “chaos” in drainage networks: The phenomenon of mixed and misconnected rainwater and sewage in old urban areas is common. Every time it rains, a large amount of rainwater mixes into the sewage pipes, causing the sewage treatment plant to operate beyond its capacity. The mixed sewage is easily discharged directly into the river through the overflow outlet, becoming a stubborn problem of black and odorous water bodies. At the same time, pipeline siltation and collapse are also very easy to cause urban waterlogging in rainstorm.
• 3. “Blind spots” and “passivity” in operation and maintenance management: In the past, underground pipeline networks were often in a state of “invisible and intangible”. The lack of online monitoring and accurate hydraulic models makes pipeline scheduling highly dependent on manual experience, often resulting in a passive situation of “treating the head when the head hurts and treating the foot when the foot hurts” where there is leakage and blockage, and where there is waterlogging and drainage.

Wisdom Awakening: From “Blind People Touching Elephants” to “Digital Twins”

Faced with these “old diseases”, the management of water supply and drainage networks is undergoing a deep awakening of digitization and intelligence. Empowered by the Internet of Things, big data, and digital twin technologies, underground “blind spots” are becoming transparent “smart zones”:

• 1. Global perception neural network: By deploying intelligent sensing devices such as flow, pressure, and water quality at key pipeline nodes, cities are building a real-time monitoring network covering “source pipeline network water plant river channel”.. By combining CCTV pipeline robot detection and acoustic leak detection technology, the “lesions” such as corrosion, sedimentation, and leakage in the pipeline network can be accurately identified and located.
• 2. The intelligent brain of digital twins: Based on high-precision hydraulic models and GIS geographic information systems, the underground pipeline network of the physical world is mapped 1:1 to digital space.. Managers can carry out real-time simulation and emergency plan deduction on the virtual platform to achieve accurate scheduling from the water source to the user leader, which can not only significantly reduce the energy consumption of the pump station, but also pre lower the water level of the pipe network before the rainstorm to calmly deal with the risk of waterlogging.
• 3. Precise and minimally invasive repair techniques: Say goodbye to the large-scale excavation of “rifling and belly breaking” in the past, non excavation repair techniques (such as UV curing, spiral winding, etc.) are becoming mainstream.. This minimally invasive surgery not only has a short construction period and minimal impact on traffic, but also effectively restores the structural strength and overcurrent capacity of the pipeline, greatly extending the service life of the pipeline network.

Value Reshaping: From “Cost Center” to “Resource Source”
In the context of the “dual carbon” goal and ecological civilization construction, the role positioning of the water supply and drainage pipeline network is also undergoing a fundamental leap. It is no longer just seen as a “cost center” that requires continuous investment in maintenance, but is transforming into a “source of value” for ensuring water security, recycling energy and resources:

• 1. The * * * cycle of water resources: Through strict rain and sewage diversion transformation and pipe network leakage control, the sewage collection efficiency has been greatly improved, providing high-quality water sources for the high-quality reuse of recycled water and truly realizing the ecological closed loop of “sewage turning into clean springs”..
• 2. Recycling and utilization of energy and resources: Modern drainage systems are beginning to pay attention to the chemical and thermal energy contained in sewage.. Through technologies such as advanced anaerobic digestion, sewage treatment plants can not only achieve energy self-sufficiency, but also recover strategic resources such as phosphorus from sludge, upgrading traditional pollutant treatment plants into “production factories” for green energy and resources.

Conclusion

 
The intelligent transformation of the water supply and drainage pipeline network is a systematic project related to urban resilience, ecological security, and people’s well-being. When every section of the pipeline is endowed with the ability of “perception”, and when the flow of every drop of water becomes clear and controllable, the city under our feet has a stronger “metabolism” ability. This buried network of intelligent life is silently supporting the prosperity and vitality of modern cities in a healthier, greener, and more sustainable manner.
