Overview of works
We have strengthened our trenchless rehabilitation capabilities through the investment in a state-of-the-art KASRO Electric Robotic Cutting System.
Designed and manufactured by ProKASRO Mechatronik GmbH, the new system enables operators to diagnose defects and carry out precision rehabilitation work within sewer networks, without the need for excavation.
The technology has been integrated into a bespoke robotic cutting vehicle, developed in partnership with MiniCam which makes it one of the most advanced sewer rehabilitation facilities of its kind in the UK.
Key drivers
- Expanding Claret’s trenchless rehabilitation capabilities
- Investing in innovative, industry-leading technology
- Reducing carbon emissions through low-carbon operations
- Minimising excavation and disruption to communities
- Improving efficiency and productivity on sewer rehabilitation projects
- Strengthening service offerings for infrastructure clients
The equipment
The KASRO Working Robots have been specifically developed for rehabilitation and repair works within sewer networks and can operate in pipe diameters ranging from DN130 to DN800.
Controlled remotely by trained operators from a workstation within the cutting vehicle, the robots can perform a range of rehabilitation activities, including:
- Milling and grinding
- Injection and filling operations
- Pipe moulding repairs
- Removal of roots and deposits
- Elimination of encrustations
- Cutting protruding connections
- Reinstating lateral connections following lining works
By carrying out repairs from within the sewer, the technology significantly reduces the need for excavation, road closures, noise and disruption to local communities.
Our approach
Selecting the right technology
Claret sought a robotic system that aligned with its sustainability ambitions whilst maintaining the durability and performance required for demanding operational environments.
Working closely with Simon Little, International Business Development Manager at ProKASRO, the team evaluated available solutions and identified the KASRO Electric System as the ideal fit.
Key benefits included:
- Capability to operate across a wide range of pipe diameters
- Robust engineering and reliability
- Enhanced operational flexibility
- Battery-powered operation
- Reduced environmental impact
Building a bespoke facility
To maximise the capabilities of the new robotic system, Claret partnered with MiniCam to develop a cutting vehicle.
The project included:
- Installation of the KASRO robotic equipment
- Integration of a new mainline CCTV inspection system
- Development of a purpose-built operator workstation
- Installation of modern welfare facilities
- Optimised storage and equipment management systems
The result is a fully integrated robotic cutting facility that has been designed to deliver efficient rehabilitation services across the UK.
Innovation
Innovation sits at the heart of this investment.
Low-carbon operations
Unlike traditional diesel-powered alternatives, the KASRO Electric System can be powered using rechargeable battery technology.
Advanced robotic rehabilitation
The technology enables highly accurate remote repairs within live sewer networks and reduces the need for excavation.
Integrated CCTV technology
The inclusion of a state-of-the-art CCTV survey system allows inspection, diagnosis and repair activities to be completed from a single vehicle which reduces project durations.
