Currently, urban underground drainage pipe networks are often difficult to inspect or monitor, creating significant challenges for regulatory authorities. Illegal sewage discharge and undetected contamination are common problems. Relying solely on manual inspection and management is extremely difficult. Therefore, management departments need to adopt advanced technologies and shift their approach to achieve quantitative, scientific, and precise sewage network management.

In one county, a sewage pipe network inspection encountered a persistent issue: the concentration of pollutants entering the wastewater treatment plant from a certain area was unusually low, indicating unknown illegal sewage discharge. Management personnel conducted inspections at various pipe network nodes by manually using handheld instruments to take on-site samples and then aggregating the data. Eventually, they identified a significant discrepancy in water flow and quality between two points along a particular section of the pipeline, which led to enforcement action against the illegal discharge. However, this process was time-consuming, labor-intensive, and prone to high error rates. Once an error occurred, it was difficult to trace back, severely hampering sewage treatment efforts.

To address this, WideIOT offers a highly reliable online monitoring system for sewage pipe networks, helping to quickly and accurately identify the sources of illegal sewage discharge. By deploying data acquisition terminals at different points in the network and connecting them to flow meters, water quality monitors, and other instruments, the system can collect real-time data on flow rate and water quality. This data is transmitted via 4G networks to a centralized management platform. Based on the platform’s visual interface, managers can view changes in flow, water quality, and other parameters across various nodes, enabling them to precisely locate illegal discharges and other anomalies. They can then rapidly mobilize personnel and resources to address water pollution issues and ensure the smooth operation of sewage treatment.

Key Functions

1. Multiple communication interfaces (serial ports, Ethernet ports, I/O ports, etc.) to connect to flow meters, water level gauges, water quality monitors, and other devices, enabling data collection on key indicators such as flow rate, velocity, COD, ammonia nitrogen, pH, and suspended solids (SS) at critical nodes in the network.

2. Data resumption upon breakpoint resume, multi-network backup, and automatic reconnection. In the event of a network failure, the system automatically switches to an available network or temporarily stores data locally. Once the network connection is restored, it automatically sends the complete set of previously unsent data, ensuring the continuity and integrity of monitoring data.

3. Multiple visualization formats on the platform, including GIS maps, dashboards, trend curves, and reports, allowing users to intuitively view real-time and historical data for each monitoring node. Data can be filtered and compared by area, pipe segment, time, and other dimensions.

4. Customizable alert thresholds (e.g., sudden increases or decreases in flow, abnormal fluctuations in COD levels, etc.). If monitored data exceeds the set range, the system will automatically notify relevant personnel via SMS, email, or other methods.

5. All monitoring data can be stored in cloud databases (e.g., MySQL, SQL database), meeting requirements for reporting to environmental authorities, assessment and uation, and law enforcement evidence collection. This provides a reliable basis for uating the effectiveness of sewage treatment and supporting long-term management.
