To enhance urban flood defense capabilities and improve the water ecological quality of the watershed, Lianyungang Gangcheng Water Co., Ltd. has carried out the Haizhou District Sewage Interception and Storage and Water Environment Comprehensive Management Project. The main tasks in the first phase of this project include renovating the outlets along four core urban rivers (Dongyan River, Xiyan River, Dapu River, and Yudai River), improving rainwater and sewage pipelines, and building new artificial wetlands. At the same time, an integrated plant-network operation and control platform will be built to achieve precise sewage interception and solve issues such as water pollution and rainy season overflow. Our company won the bid for the procurement (including installation and commissioning) of intelligent control system instruments and meters for this phase I project, providing data support for real-time monitoring of pollution load changes.
The sewage pumping station is a key node in the sewage interception system. The project deploys integrated small water quality monitoring stations at 24 pumping stations, using hash COD online analyzers and ammonia nitrogen online analyzers to monitor pollutant concentration changes in real time, supported by two rain gauges providing meteorological data support; At the same time, Siemens external clam-on ultrasonic flowmeters are installed on the outlet pipes, allowing instruments to be installed without damaging the pipes, balancing efficiency and safety.
All 27 newly built interception wells are equipped with radar level meters. Through real-time liquid level data transmission, managers can dynamically adjust interception strategies to avoid the impact of pollutants in early rainwater and improve storage capacity.
The project deployed multi-parameter water quality hydrological monitors + radar level meters + Doppler flow meters at 30 rainwater inspection wells and 47 sewage inspection wells, enabling real-time monitoring of water level and flow velocity changes in rainwater and sewage networks. In 27 key water quality monitoring areas, hash COD and ammonia nitrogen online analyzers were added to capture water quality anomalies and provide data support for pollution tracing. Each interception well and pipeline monitoring point is equipped with wireless transmission modules and power devices to ensure stable power supply and real-time data transmission.
Currently, all monitoring equipment in the project has been installed and commissioned. After multiple tests, data collection has been smooth and meets design requirements. A comprehensive intelligent monitoring system covering "pipeline sensing - pump station regulation - interception and storage regulation" has been successfully established, enabling management personnel to grasp the operational status of the pipeline network in real time, promptly warn of abnormal water quality and overflow risks, providing precise data support for pollution tracing, load analysis, and emergency dispatch, and significantly enhancing the intelligence level of regional water environment management.
