Does the water plant lose 13 tons of water for every 100 tons produced? This wireless pressure transmitter solution helps save millions in costs.
2026-08-05
Open the financial statements of any water utility, and the figure under “Water Supply Production‑Sales Loss” is often the most glaring.
According to data from the Statistical Yearbook of Urban and Rural Construction, China’s national average overall water loss rate stands at 12.68%. This means that for every 100 tons of water produced, nearly 13 tons “disappear into thin air” during transmission—neither consumed by users nor accounted for in official records, but rather quietly leaking through cracks in aging pipelines and loose joints.
Notably, the National Development and Reform Commission and the Ministry of Housing and Urban–Rural Development jointly issued the “Three-Year Action Plan for Controlling Water Loss in Urban Water Supply Networks (2025–2027),” which sets a clear target: by 2027, the leakage rate of public water supply networks nationwide will be kept below 8%. Furthermore, on June 1 of this year, the Regulations of the People’s Republic of China on Water Supply (State Council Order No. 831) officially came into force, explicitly designating the control of water‑supply network losses as a statutory obligation of water‑supply entities. As a result, water loss has transitioned from a mere “management issue” to a “legal red line.”
With policy red lines firmly in place, the traditional model of manual inspections and reactive repairs can no longer sustain itself.
What the water treatment plant needs is a digital neural network that can “see” every inch of the pipeline network.
S680L—The “24/7 Sentinel” of the Water Supply Network
What makes controlling pipeline network leakage so challenging? It’s not that we’re unaware of the leaks; it’s that we can’t pinpoint their exact locations.
Traditional approaches rely on manual inspections, with operators walking along pipelines while holding listening rods; even a skilled technician can cover only a few kilometers per day, and they are often left helpless when dealing with deeply buried pipes. Meanwhile, if pressure monitoring points are deployed via wired connections, the costs of excavating roadways and laying cables can be enough to raise eyebrows at any water utility’s budget.
The Songnuo Alliance CYB‑S680L wireless smart pressure transmitter was specifically designed to resolve this very contradiction.
This product is specifically designed for harsh outdoor environments, with an IP66 protection rating. It operates reliably whether faced with torrential rains in the south or extreme cold in the north, supporting a wide operating temperature range from –20°C to 80°C. Powered by a 7.2V disposable lithium battery, it draws less than 150 mA during data transmission and consumes under 30 μA in sleep mode—enabling long‑term, maintenance‑free operation once deployed.
S680L Wireless Smart Pressure Transmitter
At the sensing level, the S680L delivers measurement accuracy as high as 0.2% of full scale, with a range spanning from 0 kPa to 7 kPa and up to 150 MPa, enabling flexible adaptation to diverse pressure conditions. Whether it’s low‑pressure water supply in residential areas or high‑pressure operation in long‑distance transmission mains, it ensures precise performance across all scenarios. At the communication level, it supports multiple connectivity options, including NB‑IoT, 4G, and 5G, allowing pressure readings, alarm thresholds, battery voltage, signal strength, and even device location data to be seamlessly uploaded to the management platform—without the need for wiring.
In practical applications, water utilities can deploy the S680L at key nodes in the distribution network to establish a comprehensive pressure‑sensing infrastructure. Leveraging full‑network pressure data and advanced platform algorithms, the system detects abnormal pressure fluctuations, automatically issues early warnings, and helps pinpoint leak locations. When combined with nighttime minimum‑flow analysis through zone‑based metering, it further enhances the accuracy of leak localization. Field experience demonstrates that pressure‑sensor‑based leak detection can reduce emergency repair times from several days to just a few hours.
For a medium-sized water utility, every 1-percentage-point reduction in the leakage rate translates into the direct recovery of annual water‑bill losses amounting to hundreds of thousands, or even over a million, dollars.
S680N — The “Dual-Channel Intelligent Brain” for Pump Stations and Process Units
If the S680L is the “sentinel” of the pipeline network, then the CYB‑S680N serves as the “intelligent brain” for pump stations and water‑treatment processes.
The S680N and S680L both belong to the Songnuo Alliance CYB‑S680 series of wireless smart pressure transmitters, sharing core features such as ultra-low power consumption, wireless communication, and Beidou positioning. However, what sets the S680N apart is its single‑channel or dual‑channel design.
S680N Wireless Smart Pressure Transmitter
This design delivers substantial value in real-world applications. Take a water‑treatment plant’s pump station as an example: the inlet and outlet pressures of the pump are two critical parameters that must be monitored simultaneously. Traditional solutions require installing two separate pressure transmitters, which not only increase equipment costs and installation effort but also consume additional data‑transmission channels. In scenarios where both pressures need to be measured at the same location, the S680N can acquire both inlet and outlet pressure signals with a single device—cutting equipment count, installation man-hours, and maintenance points by half.
In terms of range configuration, the S680N offers independent range options for both inlet and outlet pressures, covering a broad span from 0 to 0.01, 0.1, 1, and up to 150 MPa, enabling flexible adaptation to pump operating conditions with varying head requirements. With a minimum operating temperature of −20°C, it is well suited for outdoor pump stations in cold northern regions.
From “Human-Driven” to “Data-Driven”—A Complete Closed Loop for Cost Reduction and Efficiency Enhancement
What can a wireless smart pressure transmitter deliver? It offers far more than just a single data point—it enables a comprehensive upgrade of your entire management system.
First: Leakage costs have been significantly reduced.
The National Development and Reform Commission and the Ministry of Housing and Urban–Rural Development have previously launched pilot projects to address water‑loss in public water‑supply networks in 50 cities and county seats, paving a proven pathway for nationwide implementation. As of 2026, these best‑practice approaches are being scaled up across the country; leveraging the S680L‑based, citywide pressure‑sensing network, water utilities can swiftly align with pilot‑level standards, enabling precise leak localization and rapid response.
Second: Labor costs have been significantly optimized.
Under the traditional inspection model, a water treatment plant requires dozens of personnel to conduct daily patrols along the pipeline network. With the deployment of wireless sensors, inspection frequency can be significantly reduced, allowing staff to shift their focus to higher-value analytical and decision-making tasks.
Third: From “reactive repair” to “proactive maintenance”
Long-term accumulation of pressure data enables the establishment of a baseline for equipment health; when abnormal trends deviate from this baseline, the system platform issues early warnings, transforming sudden pipe bursts into planned maintenance.
Ending
From pipeline networks to pump stations, and from leak‑loss control to energy‑consumption optimization, the two wireless smart pressure transmitters—Songnuo Alliance’s CYB‑S680L and CYB‑S680N—are helping an increasing number of water utilities transition from “manually driven” operations to “data‑driven” management.
In a regulatory environment where leakage‑control requirements are steadily tightening and the Water Supply Regulations have been fully implemented, and amid an industry trend that demands meticulous management of every drop of water, wireless smart pressure transmitters are no longer merely an “optional choice” but rather an essential piece of infrastructure.
Let data manage your pipeline network, and let algorithms help you cut costs—this is what the water treatment plant of the future should look like.
