Comprehensive Urban Water Environment Management and Control Solution

　　 Purpose of Construction

　　Establish an intelligent water‑environment management and control system to enable end-to-end monitoring, from wastewater dischargers to effluent discharge. By strengthening source‑level regulation, this system will help sustainably improve urban water‑environment quality.

　　 Management Approach

　　Conduct on-site inspections of key water bodies to enable intelligent source control.

　　Monitor drainage cross-sections to enable pollution source tracing.

　　Conduct a comprehensive analysis of water quality compliance to enable intelligent assessment and decision-making.

　　 System Composition

　　The water environment management system comprises several subsystems:

　　 ① Drainage Facilities Management System

　　Drainage facility management encompasses the asset management of hydraulic infrastructure—including pipeline networks, pumping stations, gates, and monitoring instruments—and involves maintaining a centralized database that records instrument and meter specifications, manufacturer details, service contact information, and other relevant data. This facilitates effective asset management by the owning department and ensures that, in the event of a facility malfunction, manufacturer contact information can be promptly accessed, thereby minimizing the impact of such failures.

　　 ②River and Lake Water Environment Monitoring System

　　Round-the-clock online monitoring of water level, flow rate, and water quality at key discharge outlets, combined with manual inspections, ensures that effluent quality and the aquatic environment meet regulatory standards.

　　 ③ Drainage Network Operation Monitoring System

　　Based on the urban pipeline GIS system, online monitoring devices are deployed to collect and analyze data on drainage facilities, pipeline water levels, pipeline flow rates, and cross‑sectional water quality. When abnormal conditions such as water quality exceeding standards, water levels surpassing thresholds, pipeline blockages, or equipment malfunctions occur, the system can categorize and push alarm notifications in real time to management personnel or maintenance units.

　　 ④ Wastewater Pump Station Information Management System

　　The system provides unified management of sewage lift pump stations, sewage interception pump stations, pump station equipment information, pump station operating status, and pump station electrical power data, while integrating and analyzing, processing, and visualizing upstream and downstream wastewater monitoring data.

　　Electric valves are installed at the discharge outlets of industrial wastewater pipelines. When the system platform detects that the effluent’s water quality or flow rate exceeds preset thresholds, it triggers an alarm and enables remote control of the valve’s opening and closing, thereby mitigating the impact of wastewater discharges on the city’s overall aquatic environment.

　　 ⑤ Wastewater Treatment Plant Information Management System

　　Integrate with the existing information system of the wastewater treatment plant to acquire, via data interfaces, relevant data sources—including flow rates, water quality, and operational status—for the three stages of wastewater treatment: influent, in‑process treatment, and effluent.

　　 ⑥ Video Surveillance System

　　By installing video surveillance at key facility locations, discharge outlets, and plant sites, and by remotely monitoring the surrounding environment, on-site audio‑visual data are provided to support management decision‑making and incident response.

　　 ⑦ Intelligent Inspection and Operations & Maintenance System

　　The intelligent inspection and maintenance system is primarily designed for management personnel and operations‑and‑maintenance staff. It allows users to configure routine inspection and maintenance schedules, automatically assigning inspection tasks to field inspectors when the scheduled intervals expire. Additionally, in response to abnormal conditions detected by the system, it can automatically generate and dispatch inspection work orders to the maintenance team. Upon receiving an assignment, inspectors conduct on‑site inspections, capture photos of the observed conditions, and submit feedback. The system then evaluates and analyzes both the submitted feedback and the data collected by the platform.

　　The managing entity initiates a work order, while the operations and maintenance unit handles the order through a series of steps, including acceptance, processing, and response. The managing entity can monitor the entire handling process and set time limits for completion. This approach enables standardized workflow management of work orders, accelerates fault resolution, and ensures the efficient operation of the information management platform.

　　 ⑧ Decision Support System

　　Based on a GIS system and enriched with comprehensive thematic map layers, and supported by appropriate software and hardware, the urban water‑environment discharge process is visualized, thereby providing services for the management, analysis, and decision‑making related to urban wastewater discharge.

　　Source‑tracing analysis: When water quality exceeds regulatory limits at the inlet of a sewer network, pumping station, or wastewater treatment plant, and source‑tracing is required, GIS‑based mapping can be used in conjunction with real‑time monitoring data from discharge points—including individual users, sewer lines, and pumping stations—to trace pollution sources upstream along the pipeline network. This approach helps identify potential contamination sources, enabling prompt on‑site verification and corrective action to effectively curb and manage pollution at its origin.

　　 ⑨ Water Environment Integrated Management App

　　Synchronize data with the PC client to enable collaborative mobile querying and processing of PC‑side functionalities. Its key features include real-time monitoring, live video, early warning notifications, task management, inspection and patrol tracking, announcements and notices, and a contact directory, among other mobile‑app capabilities.
