News - Water Quality Monitoring Solution for Rainwater Outlets

‌

What is a "Rainwater Pipe Network Monitoring System"?

The online monitoring system for rainwater outlet pipe networks leverages digital IoT sensing technology and automated measurement methods, with digital sensors as its core. This integrated system combines multi-parameter water quality monitoring, remote signal transmission, and data display and analysis functions. Comprising an automated monitoring station and an IoT-based big data platform, it forms a comprehensive management framework. Its capabilities include water quality measurement, remote communication, data storage, querying, trend analysis, and alarm early warning, enabling full-process monitoring of multiple water quality parameters. This system provides a robust data foundation for online oversight and planning support of rainwater pipe networks.

The system is structured into four layers:

·Perception Layer‌: Composed of advanced intelligent digital IoT sensors, it continuously monitors water quality and hydrology in the rainwater pipe network, outputting digital signals for real-time data collection.

·Network Layer‌: The intelligent monitoring station supports multiple communication modes (e.g., NB-IoT, GPRS, CDMA, Ethernet) to upload data to the monitoring platform for storage and analysis.

·Platform Layer‌: The IoT detection platform centralizes data display and analysis, offering functions such as real-time water quality detection, trend analysis, valve control data query, and early warning alerts.

·Application layer: The data obtained from water quality monitoring in the rainwater pipe network can be utilized in various domains, including emergency command systems, digital urban management, safe city initiatives, government service hotlines, environmental monitoring, and intelligent transportation systems.

‌What Parameters Need to Be Monitored for Rainwater Pipe Network Water Quality?

The core parameters for water quality monitoring in stormwater networks include:

·pH Value‌: Indicates acidity or alkalinity; normal clean rainwater has a pH of ~5.6. Values below this may indicate acid rain, which can corrode pipes and harm ecosystems.

·Conductivity‌: Reflects total ion content; pure rainwater typically has a conductivity of 5–20 μS/cm. Elevated levels may suggest industrial or marine pollution.

·Turbidity‌: Measures water clarity; high turbidity indicates sediment or particle contamination, affecting aquatic transparency.

·Chemical Oxygen Demand (COD)‌: Assesses organic pollutant levels; excessive COD consumes dissolved oxygen, disrupting ecological balance.

·Ammonia Nitrogen‌: Primarily from domestic sewage and agricultural runoff; high levels can cause eutrophication and algal blooms.

·Water Temperature‌: Influences aquatic ecology and microbial activity; a critical baseline parameter.

Additional parameters such as sulfate, nitrate, chloride ions, and suspended solids (SS) may also be monitored based on specific requirements. Tracking these indicators helps identify pollution sources, ensure safe rainwater discharge, and protect urban water environments.
