Jinan Mountain Water Supply Project

Jinan Mountain Area Water Supply Project – Online Water Quality Monitoring

The Jinan Mountain Area Water Supply Project is a key livelihood initiative aimed at ensuring basic public welfare, building a safe drinking water defense line in mountainous areas, and promoting the transition of water supply from “having water to drink” to “drinking good water.” The project mainly covers areas such as the southern mountain region of Jinan, serving hundreds of villages and hundreds of thousands of residents, while also providing supplementary functions such as agricultural irrigation and ecological water replenishment. It is a core infrastructure project for improving the modern water network of Jinan and ensuring the safety of production and domestic water for the mountain population.

As an important ecological barrier and water conservation area, the Jinan mountain region features complex terrain, scattered villages, and weak water supply facilities. Influenced by the local climate and topography, water sources are susceptible to agricultural non‑point source pollution, surface runoff erosion, and other factors, resulting in large fluctuations in water quality. Traditional manual sampling monitoring suffers from long cycles, delayed data, inconvenient outdoor inspections, and limited coverage. These shortcomings fail to meet the requirements of the Standards for Drinking Water Quality (GB 5749‑2022) and the need for refined control of water supply in mountainous areas. To address these monitoring gaps and achieve full‑process water quality control for the mountain water supply, ensuring that residents have access to “safe and secure drinking water,” the Jinan Mountain Area Water Supply Project was launched. The project centrally deploys outdoor multi‑parameter online water quality monitors, establishing a comprehensive, intelligent, and round‑the‑clock water quality monitoring system. This promotes a shift in water quality supervision for mountain water supply from “post‑incident investigation” to “pre‑event prevention and real‑time control,” providing solid technical support for water supply safety in mountainous areas.

Monitoring System and Deployment

This project combines the topographical characteristics of the Jinan mountain region, the distribution patterns of water sources, and the coverage of the water supply network. Using outdoor multi‑parameter online water quality monitors as the core monitoring equipment, monitoring points are scientifically deployed to achieve seamless, full‑chain coverage of the mountain water supply. Key monitoring points are located at water sources (reservoirs, mountain springs, water intakes), booster pumping stations, key nodes of the water transmission pipeline network, village water supply stations, and terminal water supply points. The monitoring also covers sensitive areas prone to water quality fluctuations, such as remote villages and water source confluences, ensuring comprehensive capture of water quality dynamics throughout the entire process from source water extraction, pipeline transmission, to terminal supply.

The multi‑parameter online water quality monitors focus on the core needs of drinking water safety in mountainous areas. They primarily monitor key water quality indicators such as water temperature, pH, dissolved oxygen, electrical conductivity, turbidity, residual chlorine, COD, ammonia nitrogen, total phosphorus, and total nitrogen. Depending on the characteristics of mountain water sources, the monitoring capability can be flexibly extended to include characteristic pollutants such as heavy metals. The system strictly follows national drinking water monitoring standards and relevant technical specifications, ensuring that the monitoring data are accurate, reliable, and compliant with regulatory requirements. It fully reflects the water quality status of the mountain water supply, providing precise data support for water quality control and pollution source tracing.

Equipment Features and Capabilities

The equipment is equipped with a high‑precision sensor array and offers core advantages of automation, high stability, and strong anti‑interference capability. It integrates full‑process functions including automatic sampling, automatic pretreatment, automatic detection, automatic cleaning, automatic calibration, and intelligent quality control. It can operate continuously 24/7, significantly reducing manual maintenance workload and avoiding the inconvenience and safety risks of outdoor manual inspections in mountainous areas. It supports 4G/NB‑IoT wireless data transmission technology, enabling real‑time upload of monitoring data to a platform for real‑time data viewing, historical data retrieval, and anomaly alerting. When any monitored indicator exceeds the safety threshold, the system rapidly triggers multi‑level alert signals, allowing staff to promptly identify risks and take emergency response measures to prevent water quality safety hazards.

Project Outcomes and Significance

The implementation of this project has comprehensively improved the intelligence and precision of water quality control for the mountain water supply in Jinan, effectively addressing the shortcomings of traditional monitoring methods and achieving closed‑loop management of “real‑time monitoring, precise early warning, rapid response, and full‑process control” for the mountain water supply. This aligns with the relevant requirements of Jinan’s modern water network construction and mountain water supply assurance.

The continuous and stable operation of the outdoor multi‑parameter online water quality monitors not only provides accurate data support for mountain water supply management authorities to understand water quality dynamics, identify pollution risks, optimize water supply processes, and ensure water supply safety – helping to improve the long‑term maintenance mechanism for mountain water supply and enhance the quality of water supply services – but also effectively guarantees the drinking water safety of the mountain population. It has fundamentally changed the previously lagging situation of water quality monitoring for mountain water supply, allowing residents to access safe water simply by turning on their taps.

Moreover, the implementation of this project improves the water supply monitoring system in the Jinan mountain region, promotes the high‑quality development of mountain water supply, helps consolidate the achievements of poverty alleviation, and advances rural revitalization. It provides a replicable and scalable intelligent monitoring solution for similar water supply projects in mountainous areas, thereby building a strong defense line for drinking water safety in the mountains of Jinan.
