Importance for the sewer rehabilitation
Methods for the rehabilitation of pipe or sewer systems are so-called Cured-In-Place Pipe (CIPP). The CIPP process uses flexible hose carriers made of corrosion-resistant synthetic fibers (needled felt) or fiberglass reinforced plastic composite (GRP fibers) impregnated with a reaction resin molding compound. The installation in the channel takes place via the manholes, in which the hose (liner) is installed either by inversion or by feeder. Curing to a solid plastic pipe (liner) can be carried out by hot curing by means of hot water, steam or by UV light curing.
The structural and operational requirements
The structural and operational requirements for renovated sewers are high. The pipe lining processes are under special control and testing, as their production in the field takes place under difficult working conditions. Ensuring a consistent quality standard is verified after the build-up by acceptance tests. Quality defects on the liner at its installation may be caused for instance by local overheating (due to excessive polymerization of the resin, a too high heat supply or a faulty composition) or by an incomplete curing. The detection of abnormalities and their precise localization along the liner makes it difficult to accept and to sample liners. Due to the risk of sinks or inlets of cold groundwater, a safety margin in energy management is taken into account, which often leads to unnecessarily long heating times.
Unique features
VeriCure® is a breakthrough technology developed to improve the CIPP curing process. Its ability to constantly monitor the temperature throughout the duration of the liner installation helps ensure a 360° cure throughout the length of the host pipe. The result is a fully rehabilitated, leak-free pipe, cured with confidence and verified with data.
Easy to use, the VeriCure optical fiber cable runs along the invert of the host pipe and is activated once the CIPP liner has been inflated and the curing process begins. With the cable plugged into the control box, VeriCure’s CMS software captures and records the thermal temperature, incrementally, along the entire length of the liner. Regardless of existing flow, VeriCure provides highly accurate and localized temperature data; helping ensure every inch of liner is properly cured.

System components of the CMS
The CMS controller can be supplied either as a mobile, portable unit for the use in the field or as 19‘‘ version for the installation in the truck of the company installing the liner.
The mobile CMS measurement device contains the under mentioned system components:
- DTS controller
- IPC with keyboard
- CMS software
- Optical connector (BlueBox) for the connection to the sensor cable
- LAN socket, WLan
- Socket for the energy supply
Powerful CMS software
By using the CMS software, the temperature measurement data can be prepared so that the user can assess and control the local and temporal curing process of the liner during the renovation process.
Standard views of the software are the so-called Zone View, the 3D Plot and the Curing View. The 3D Plot and the Curing View serve as proof of quality for a professional rehabilitation. The zone view provides the installer with clear decision criteria for the energy supply, so that the renovation can be completed successfully even on difficult construction sites.
CMS sensor cable
The CMS sensor cable is designed to be drawn from a cable drum directly into the sewer.
To ensure the quickest possible connection of the sensor cable to the CMS controller at the construction site, the sensor cable is pre-assembled with an optical plug, so that the measuring system can be set up and is ready for use in a few simple steps.
Types of CMS sensor cables
Depending on the diameter and the wall thickness of the CIPP liner, and taking into account the chosen curing process (water, steam and UV curing), different sensor cables are available for waste water and drinking water pipes to provide high mechanical protection for the fiber integrated in the sensor cable.

FAQ
What is the Distributed Temperature Sensing (DTS) method, and how is it used in CIPP liner rehabilitation?
Distributed Temperature Sensing (DTS) is a fiber-optic measurement method that enables continuous temperature monitoring along a fiber optic sensor cable. For monitoring the curing process of CIPP liners (Cured-In-Place Pipes) in sewer rehabilitation, a DTS system is used in our mobile Curing Monitoring System (CMS) with an industrial PC, a 17" touchscreen moni-tor, and a stainless steel keyboard with integrated touchpad. This system, in conjunction with our software, records, processes, and visualizes the temperature along the entire length of the liner in real-time, allowing for precise control, optimization, and high-quality assurance of the liner curing process.
What advantages does the DTS method offer compared to traditional point-based temperature measurements?
Compared to traditional point-based measurements, which are only conducted at specific lo-cations like manholes or hot water inlets, the DTS method offers continuous, seamless moni-toring of temperature along the entire length of the liner. This enables a more uniform curing process, reduces the risk of errors, and increases the liner's lifespan. Additionally, energy costs can be lowered, and CO2 emissions reduced.
What are the fiber-optic specifications of the DTS in the Curing Monitoring System (CMS)?
The CMS has a spatial range of 2 km with an adjustable resolution of 10 cm to 1 m. Meas-urement intervals and temperature recording are variable, starting from 5 seconds. The tem-perature accuracy is typically 1K (with a 1-minute measurement interval) and depends on the spatial resolution and the measurement duration. The CMS is calibrated to our sensor cable, which is specifically designed and tested for sewer rehabilitation. Only coordinated system components can ensure temperature accuracy. Other sensor cables from third-party providers cannot be used with the measurement system as they are not calibrated to the DTS, resulting in high temperature deviations.
How does the Curing Monitoring System (CMS) contribute to reducing energy costs, resources, and CO2 emissions?
By precisely monitoring and controlling the curing process, the required energy can be opti-mally dosed, leading to more efficient use of resources. This reduces energy costs and CO2 emissions. Additionally, the time required for curing on the job site is shortened, which fur-ther saves energy and resources.
How does the Curing Monitoring System (CMS) contribute to quality control and assurance?
The CMS documents the entire curing process by continuously recording temperature data along the liner. This data can be analyzed afterwards to ensure that the liner has been evenly cured throughout. A summary of the process can be provided to the customer in paper or digi-tal PDF format as proof of quality. Analysis or playback of the curing process can also be performed at any time using the rec-orded data.
How does the use of the Curing Monitoring System (CMS) affect the lifespan of the rehabilitated pipeline?
The even and controlled curing of the liner using the DTS method improves the structural integrity of the liner, resulting in a longer lifespan for the rehabilitated pipeline. Precise moni-toring minimizes the likelihood of weak points or defects, which could otherwise lead to fu-ture repairs or additional investments.
What documentation is created by the Curing Monitoring System (CMS), and how can it be used?
Upon project completion, the software can generate a detailed documentation of the tempera-ture profile along the entire length of the liner during the curing process. This data can be used for quality control, report generation, and as proof that the rehabilitation work was properly carried out. This facilitates traceability and provides a transparent basis for future inspections and planning.
Is there a difference between the so-called VeriCure system and the CMS?
No, VeriCure is the new brand name for the Curing Monitoring System (CMS).
