Innovative Drain Relining Using UV Pip Lining for Industrial Effluent Pipes
Metro Rod Newport & Hereford was tasked with a critical drain relining project at a food processing factory in Leominster, England. The factory’s 450mm effluent pipework required urgent attention after routine CCTV surveys revealed defects along a 65-metre section. Using the latest UV pipe lining technology, Metro Rod implemented a precise, efficient, and long-lasting sewer lining repair solution. This case study highlights the challenges, the innovative solution applied, and the successful outcomes achieved for this manufacturing maintenance project.
The Challenge: Maintaining Manufacturing Effluent Pipes with Sewer Lining Repair
The factory’s effluent pipework is surveyed annually as part of a Planned Preventative Maintenance (PPM), but during the inspection, several defects were identified in a critical 65-metre section. The main challenge was to repair the pipework efficiently without disrupting factory operations or contaminating the effluent system. Traditional pipe replacement would have been disruptive, costly, and time-consuming. Metro Rod needed to come up with a solution that would restore structural integrity while minimising downtime, making advanced UV pipe lining the ideal method for a safe and effective sewer lining repair.
The Solution: Precision UV Pipe Lining and Drain Relining
Metro Rod deployed a comprehensive solution combining cutting-edge drain relining and UV pipe lining technology. The process began with pre-cleansing the pipe using a water recycling tanker, ensuring all debris and deposits were efficiently removed. Next, a Prokasro 4.0 robotic cutting unit was used to remove three protruding 150mm VC connections, which posed blockages within the pipework. All incoming connections were then capped off with drain stoppers.
The SEARTEX 4mm UV liner was carefully inserted using a trailer-mounted winch. The curing process, assisted by the SpeedyLight LED system, passed along the 65-metre pipe at 0.36 metres per minute, initiating an exothermic reaction that cured the liner completely. This technique allowed the pipework to be relined without the need for sunlight and with zero water contact during installation, critical for optimal curing. Once cured, lateral connections were reopened, the ends trimmed to a smooth finish, and a post-installation CCTV survey confirmed the integrity of the sewer lining repair.
The entire operation was completed by a team of nine engineers over 15 hours, demonstrating Metro Rod’s capability to deliver industrial-scale drain relining projects efficiently while adhering to strict health and safety protocols.
The Outcome: Long-Lasting Sewer Lining Repair with Minimal Disruption
The UV pipe lining installation successfully restored the structural integrity of the 450mm effluent pipework. The innovative drain relining solution provided a durable, long-lasting sewer lining repair without the need for costly excavation or major operational downtime. The client received a detailed survey report confirming the liner’s condition, offering peace of mind and assurance of continued smooth operation. This project demonstrates how Metro Rod can deliver efficient, reliable sewer lining repair solutions for the manufacturing sector, helping facilities maintain essential operations with minimal disruption.
