Pressure measurement in sewer networks: How Wessex Water anticipates serious leaks with state-of-the-art pressure sensors
In modern sewer systems, precise pressure measurement is not only a technical necessity, but it is a also a crucial factor for the safety, efficiency and sustainability of operations. Small leaks or hidden pipe breakages can generate enormous costs over the long term and pose a threat to the environment long before they are noticed. For Wessex Water, a municipal network operator in the United Kingdom, this was precisely the motivation for upgrading the pressure monitoring system in its sewer networks.
They chose VEGABAR 28 from the VEGA BASIC series, a state-of-the-art pressure transmitter with switching function. The integration of this pressure sensor into Wessex Water’s existing monitoring system demonstrates impressively how modern pressure instrumentation can revolutionise the operation of sewer networks.

The challenges of pressure monitoring in sewer networks
Sewer networks place special demands on the deployed measurement technologies. Sensors and transmitters have to operate reliably in damp, flood-prone and often confined conditions. Conventional instruments can quickly reach their limits here: manual adjustment is time-consuming and expensive, the output data can become inaccurate and breakdowns can result in costly repairs.
The primary task of a pressure transmitter in a sewer network is to detect pressure changes at an early stage. A sudden drop in pressure can indicate a burst pipe, whilst a long, gradual loss of pressure suggests small leaks or untight seals. Only through precise pressure measurement can a timely response be initiated and costly damage prevented.
Wessex Water reviewed its requirements for a pressure monitoring solution. The engineers at Wessex Water agreed that the instrument had to be advanced and robust, yet easy to use, without compromising on accuracy and reliability.

VEGABAR 28: Precision meets robustness
Modern pressure instrumentation enables early detection of leaks in sewer networks.
The decision to use VEGABAR 28 was no coincidence. This pressure transmitter offers the combination of state-of-the-art pressure measurement technology and user-friendly operation, making it ideal for use in sewer networks.
A key advantage for Wessex was the ease with which the instrument was put into operation: Setting up and commissioning VEGABAR 28 takes only two minutes on average. Thanks to the transmitters' integrated simulation mode, different configurations can be tested on-site, eliminating the need for lengthy installation procedures. This not only saves time – it also minimises downtime and makes the technicians’ work easier.
The robustness of its design is a crucial factor in damp pumping stations. With its IP68 protection rating, VEGABAR 28 can withstand flooding and even complete submersion – a feature that other sensors were unable to offer in the past. Its durable, robust ceramic measuring cell ensures accurate data is delivered over many years, reducing maintenance requirements and lowering the total cost of ownership (TCO).
A high measurement frequency – 166 measurements per second (every six milliseconds) – enables the monitoring of transient hydraulic effects and the detection of even the smallest pressure changes. This is especially important for ensuring that leaks are detected quickly.

Smart integration and user-friendliness
Bluetooth-based pressure sensor technology: Parameterisation and monitoring of the pressure transmitter via an app greatly increases reliability and efficiency.
Another highlight is VEGABAR 28’s Bluetooth connectivity. Via the VEGA Tools app, engineers can access the transmitter, adjust its settings and read out data without having to enter cramped spaces. This protected, encrypted communication increases safety and prevents unauthorised changes.
The VEGABAR 28 can be seamlessly integrated into Wessex Water’s existing monitoring system, which already utilises VEGA’s EDM, level and flow measuring instruments. This was made possible by VEGA’s reliable customer service both before and after installation, which was highly appreciated by the operators. The result is a consistent, reliable pressure monitoring system that simplifies maintenance planning and boosts efficiency.

Operational advantages for Wessex Water
Since the installation of VEGABAR 28, the benefits of using this pressure transmitter have become clear:
- Early problem recognition: Pressure drops and deviations are detected immediately, enabling rapid reaction and initiation of repair work.
- Reduced maintenance requirements: The ease of use and robust design of the sensor reduces operational costs.
- Cost efficiency: The combination of low failure rate, simple setup and long-lasting sensor technology significantly reduces total operating costs.
The ability to detect leaks and pipe breaks at an early stage not only minimises water loss, it also prevents potential environmental damage, maintains customer services and protects the company’s reputation. Sewage networks monitored by precise pressure measurement benefit in the long term from stable operational processes and improved compliance with environmental regulations.
Future-proof pressure instrumentation for the water sector
The use of VEGABAR 28 at Wessex Water demonstrates how innovative sensor technology for pressure can increase the reliability of sewer networks. The combined package of robust sensor-cell design, high measurement accuracy and intuitive operation makes the transmitter an indispensable tool for the system operators.
At a time when water management companies must meet increasing demands for efficiency, safety and environmental compatibility, high-quality pressure sensors like VEGABAR 28 are essential. Such instruments deliver the data to enable proactive maintenance, reduce costs and contribute to making the wastewater infrastructure fit for the future.
For Wessex Water, the investment in VEGABAR 28 has paid off in several ways: operational performance has been greatly improved, maintenance costs reduced, safety enhanced and the long-term sustainability of the networks reinforced.
