Urban drainage networks are scattered and feature complex underground environments, making comprehensive monitoring difficult with traditional sampling methods. Shandong Dongrun Instrument’s online water quality monitoring system for drainage networks can adapt to various pipeline conditions, helping municipal authorities and industrial parks achieve digitalized water quality supervision.

The urban drainage pipes are scattered in locations and the underground environment is complex. Traditional sampling monitoring is difficult to achieve comprehensive control. The Shandong Dongrun Instrumentation Online Water Quality Monitoring System for Drainage Pipelines can adapt to different pipeline conditions and assist municipal and industrial parks in completing digitalized water quality supervision. The system can be installed at key nodes of the pipelines, sewage outlets, and points of combined rainwater and sewage, and can collect multiple water quality parameters such as COD, ammonia nitrogen, total phosphorus, total nitrogen, pH, and dissolved oxygen in real time. The equipment is resistant to humidity and can withstand the harsh underground environment, and can operate stably for a long time.
The data is uploaded in real time to the management platform. Once the water quality values exceed the preset threshold, the system automatically triggers an alarm. Staff can quickly locate the abnormal pipe sections and investigate issues such as enterprises’ illegal discharges, pipeline leakage, and rainwater and sewage mixing. This changes the passive mode of post-event investigation. The entire system is easy to install and debug, and does not require large-scale excavation and renovation of the pipelines, reducing project construction costs. By continuously retaining complete water quality monitoring data, the system provides reliable data support for pipeline operation and maintenance renovations, pollution source tracing, and environmental protection reporting, helping management units improve the precision management level of drainage pipelines and effectively prevent water environmental risks, ensuring the safe operation of the urban drainage system.
