“Smart Water Arteries” Under the City: Redefining Urban Sewage Systems with Technology

Smart, energy-efficient sewage systems are reshaping urban infrastructure, supporting sponge cities, and promoting sustainability.

In the intricate network of urban infrastructure, few systems are as vital, yet as underappreciated, as sewage transportation. At the heart of the evolving urban landscape, integrated lifting pump stations are emerging as the unsung heroes of modern sewage management. These intelligent systems are transforming how cities handle decentralized sewage, making them the core component of sustainable urban water management—particularly in the development of sponge cities.

Revolutionizing Sewage Transport with Smart Solutions

Modern urban environments face unique challenges when it comes to managing sewage, especially in rapidly growing cities where traditional sewage systems often cannot cope with increasing demand. The advent of integrated lifting pump stations is addressing these challenges by combining intelligent control systems with cutting-edge technology, creating an efficient, responsive, and sustainable sewage transportation network.

At Shandong Lushun Environmental Technology Co., Ltd., we specialize in providing high-tech environmental protection solutions that contribute to the modernization of urban infrastructure. Through innovations in wastewater treatment systems, we enable cities to manage their resources efficiently and sustainably.

The Importance of Integrated Lifting Pump Stations

Integrated lifting pump stations are buried 6-15 meters underground and serve as the “nerve endings” of the urban sewage system. These stations effectively lift sewage from decentralized points and pump it toward treatment facilities. With a typical daily transportation capacity of over 200,000 tons, these pump stations are central to the success of the sponge city concept—an urban design model aimed at mitigating flooding, enhancing water retention, and promoting water conservation.

Through precise coordination of submersible pumps, intelligent control systems, and smart grids, these systems ensure sewage is transported efficiently while minimizing energy consumption and maintenance costs.

Key Technological Features of Smart Sewage Systems

Industrial Water Treatment Equipment

Multi-Source Confluence Design

A major innovation in integrated lifting pump stations is the multi-source confluence design. With DN300-DN1200 water inlet branch pipes connected to the pump station, turbulence is reduced, leading to smoother water flow. For example, in the renovation of an old community’s sewage system, the flow uniformity of five branch pipes increased to 98%, eliminating the damaging effects of water hammer—a common issue in conventional sewage systems.

Anti-Blocking Grille and Self-Cleaning Technology

To prevent blockages, the stations are equipped with a two-stage filtration system: a coarse screen (20mm gap) followed by a fine screen (5mm gap). This filtration system captures up to 180 kg of debris daily. Additionally, the inclusion of automatic backwash brushes cleans the grilles every 30 minutes, significantly reducing maintenance downtime. This high level of automation ensures reliable operation with minimal human intervention.

The “Smart Brain” Behind the Water Collection Pool

At the heart of the integrated lifting pump station lies its smart brain—the intelligent control system. It continuously monitors and adjusts liquid levels through a precise ultrasonic level meter with an accuracy of ±2mm. The system ensures the pump station operates with maximum efficiency, switching between pumps based on the liquid level. In one industrial park case, this system reduced pump starts from 48 to just 12 per day, effectively doubling the lifespan of the motor and cutting down on energy consumption.

Permanent Magnet Synchronous Motors for Efficiency

The submersible pumps used in these stations are powered by permanent magnet synchronous motors (PMSM). These motors offer energy efficiency at the IE5 level, providing a significant reduction in energy consumption. For example, a 300m³/h pumping station with these motors consumes only 0.08kW•h per ton of water, resulting in a 40% energy saving compared to traditional pumping stations.

The “Safety Artery” of the Pipeline Network

In terms of durability, HDPE spiral pipes with a ring stiffness of SN16 have replaced traditional concrete pipes. These pipes are resistant to pressure and can withstand forces up to 0.6MPa, ensuring that the pumping stations can operate safely even in extreme conditions. In one riverbank pump station, these pipes have shown a service life of up to 50 years.

Digital Twin Technology for Monitoring and Control

Thanks to Digital Twin technology, every pump station can be monitored in real time via a 1:1 virtual model. This system allows for continuous monitoring of liquid levels, flow rates, and energy consumption. By integrating AI-powered predictive analytics, the system can forecast potential pump failures with an accuracy rate of 97%. This foresight allows for proactive maintenance, ensuring minimal downtime and preventing costly repairs.

Real-Life Applications of Smart Water Arteries

Integrated lifting pump stations are not just theoretical; they are already in operation across various sectors, offering tailored solutions for diverse urban drainage challenges.

Renovating Old Residential Areas

In a second-tier city, the renovation of 200 communities involved installing underground pump stations that successfully solved the issue of regular waterlogging after heavy rainfall. The new system reduced the frequency of pipe network overflows by 90%, greatly improving residents’ quality of life.

Industrial Wastewater Treatment

In a chemical park, corrosion-resistant pump stations made of 316L stainless steel were used to transport acidic and alkaline wastewater (pH 2-12). This system has operated continuously for over 365 days without any leaks, showcasing the durability and reliability of modern sewage solutions.

Sponge City Construction

In one newly developed district, the integration of a pump station with an ecological filter tank allowed rainwater to be reused for greening purposes after pre-treatment. The result was an annual saving of 150,000 tons of water, a key achievement that earned the project the “Living Water Demonstration Project” award from the Ministry of Housing and Urban-Rural Development.

The Future of Urban Sewage Transportation: From Transportation to Smart Nodes

As cities continue to grow and evolve, so too must the systems that manage their essential infrastructure. The integrated pumping stations of today are evolving into multi-functional urban smart nodes, capable of much more than sewage transportation.

Key developments include:

  • Water quality monitoring systems that help reduce reagent use by 20% in wastewater treatment.
  • Emergency drainage units that can automatically open bypasses during heavy rainfall to boost drainage capacity by up to three times.
  • Underground space development, which allows for the creation of pocket parks above pump stations, increasing land utilization by 50%.

These technological advancements signify the shift from traditional sewage management to a more intelligent, sustainable, and efficient approach to urban water infrastructure.
