Located in Tianjin, a city of 13.64 million residents, this large-scale municipal project aimed to modernize water metering infrastructure by replacing outdated meters with advanced smart meters. With a total investment of USD 259.7 million, the goal was to improve operational efficiency, reduce water loss, and enhance customer service.
The utility faced multiple challenges:
High leakage rate of 26% and a production-sales gap of 40%
Outdated meters leading to billing inaccuracy and customer complaints
A need for wide-scale digitization and accurate remote data collection
Sanchuan Smart Technology provided a comprehensive NB-IoT smart metering solution, deploying over 1.9 million smart water meters. These meters are equipped with:
Non-magnetic ultrasonic technology for high-precision measurement
NB-IoT connectivity for reliable, low-power wide-area network communication
Seamless integration with Tianjin’s existing AMI system
High durability and long lifespan, minimizing maintenance needs
Before implementation (baseline) vs. after Sanchuan deployment:
Metric | Before | After |
Smart Meters Deployed | 180,000 | 1,900,000 |
Annual Water Supply (10,000 tons) | 59,500 | 66,700 |
Leakage Rate | 26% | 9.2% |
Production-Sales Gap | 40% | 19.2% |
Meter Readers Needed | 1,400 | 500 |
Customer Satisfaction | – | 99% |
Meter Reading Success Rate | – | 99.5% |
"Sanchuan's NB-IoT smart metering solution has completely transformed our network operations. We've significantly reduced water losses and labor costs while gaining real-time insights into usage. The 99.5% success rate in automated readings and the 99% customer satisfaction score are proof of the system's reliability and accuracy. This is a major step toward a smarter, more sustainable water utility."
