Rainwater-sewage cross-connections, wet-weather overflows, and concealed illegal discharges are common pain points in industrial park water environment management. Traditional manual inspection cannot detect pipeline network anomalies in real time, resulting in regulatory blind spots.
A complete online water quality monitoring solution for industrial park rainwater and sewage networks is the key to achieving fine-grained drainage management and meeting environmental compliance requirements. Dongrun has deep experience in park water environment monitoring and can provide customized end-to-end solutions for online monitoring of rainwater and sewage networks.
This solution deploys monitoring points at rainwater pipelines, sewage pipelines, branch nodes, and main discharge outlets. Equipped with multi-parameter water quality monitoring instruments, it enables 24/7 real-time monitoring of core parameters such as pH, COD, ammonia nitrogen, turbidity, total phosphorus, and total nitrogen. Combined with flow monitoring modules, it accurately captures the drainage conditions of the pipeline network.
The instruments are adapted to harsh underground conditions such as high humidity, heavy sludge, and high impurity levels. With built-in automatic cleaning, they effectively prevent sensor fouling and ensure long-term stable monitoring.
The solution can accurately identify rainwater-sewage cross-flow, dry-weather direct sewage discharge, wet-weather overflow pollution, intermittent illegal discharges, and similar issues. Water quality data is stored in real time, and automatic alarms are triggered for abnormal events, helping operation and maintenance personnel quickly trace and locate problematic sections.
All monitoring data supports automatic storage and report generation, is compatible with the HJ212 protocol, and can be seamlessly connected to the park’s smart management platform and environmental protection authority systems, enabling data visualization and digital management.
According to park size, industry type, and pipeline layout, Dongrun can tailor lightweight, highly adaptable rainwater and sewage network monitoring solutions. We provide end-to-end services including site survey, equipment supply, installation and commissioning, and platform integration, helping parks address rainwater and sewage management challenges and achieve long-term compliance control.
