Project Overview
The project covers a new 300,000 m³/day water treatment plant, 138 km of water transmission and distribution pipelines crossing mountainous terrain and river channels, and ecological treatment works on several inflow tributaries of the Bailianhe Reservoir. Before the upgrade, the utility relied on manual patrols, had large monitoring blind spots along the network, unstable communications, and isolated data systems — all of which put water supply safety and water quality stability at risk.
Challenges
- Very long pipeline spans across mountains and river crossings, with many monitoring blind spots
- Incomplete water quality monitoring from source to tap
- Heavy reliance on manual operation and patrol inspection
- Unstable communication links and serious data silos between subsystems
- Slow dispatch response to bursts, leaks and equipment faults
What WELK Meters Delivered
1. Smart Instrumentation System
High-accuracy water quality, flow, pressure, level and sludge-level instruments were deployed across the water source, inflow tributaries, every plant process stage and the full 138 km network — eliminating the monitoring blind spots in mountain and river sections. Manual patrol reading was replaced by uninterrupted 24-hour data acquisition that captures water quality fluctuation, abnormal network pressure and leakage in real time.
2. Production Automation (SCADA + PLC)
A complete plant automation system links coagulation, sedimentation, filtration and disinfection into one automated process chain. Chemical dosing and equipment parameters are adjusted automatically from live instrument data, while pump sets and motorized valves are remote-controlled with automatic fault alarms — removing the operator error, unstable water quality and high chemical/energy consumption of manual operation.
3. Industrial Telecom & IoT Communication
An industrial fiber-optic ring network combined with a dedicated IoT radio network was built to suit the mountainous, river-crossing site conditions. It connects instrumentation, equipment control, security CCTV and network O&M into one platform with unified data aggregation, visualization and dispatch — ending the data-silo situation and guaranteeing low-latency command transmission.
Results
- Full-coverage monitoring from source to tap; reservoir and finished water quality consistently better than the national standard
- More than 95% of the production process runs automatically; chemical and energy consumption sharply reduced
- Manual O&M cost reduced by 70%
- Network leakage rate sharply reduced; fault repair efficiency up 60%
- Water supply assurance rate raised to 99.9%

Frequently Asked Questions
Can WELK Meters supply the complete instrumentation package for a water treatment plant?
Yes. As in this project, we supply the full instrument scope from one factory: pressure transmitters and gauges, electromagnetic flow meters, ultrasonic and radar level meters, sludge level and water quality instruments, plus PLC control cabinets and telemetry. One supplier, one warranty, matching documentation.
Do your instruments integrate with SCADA and PLC systems?
Yes. All transmitters provide standard 4-20 mA / HART or RS485 Modbus outputs and are routinely integrated with SCADA platforms and PLC control systems. In this project we delivered and commissioned the SCADA + PLC automation system ourselves.
Can you deliver similar smart water projects outside China?
Yes. We export factory-direct to utilities, EPC contractors and system integrators worldwide, with English documentation, calibration certificates, OEM/ODM options and remote commissioning support.
What instruments does a smart water utility project typically need?
Typical scope: electromagnetic flow meters on raw and treated water lines, pressure transmitters and gauges along the network, ultrasonic or radar level meters on tanks and wells, submersible level transmitters in reservoirs, water quality analyzers, and IoT/NB-IoT telemetry units for remote sites.
