Millennium Main
A Thames Water large-diameter trunk main running from Nunhead Reservoir to Deptford is a critical asset Thames network, supplying water to the rapidly developing Greenwich Peninsula. Sections of the pipeline, originally constructed using glass-reinforced plastic, had suffered repeated failures and exhibited extensive deterioration, including severe blistering. These issues raised serious concerns about the pipeline’s structural integrity and compliance with Drinking Water Inspectorate (DWI) standards. Thames Water engaged Mgroup Water to lead a comprehensive programme of site investigations and develop a cost-effective rehabilitation strategy. This culminated in the successful delivery of a £21 million project to restore the trunk main’s reliability and extend its operational life.

Rehabilitation under River Beaulieu utilising Flexi-Sliplining
Picote UK Ltd successfully delivered a trenchless rehabilitation of two severely corroded DN225 pipelines running underneath the River Beaulieu in Hampshire. Using the innovative Flexi-Sliplining system, the 160-metre installation was completed in just three days, with no excavation, no disruption to local infrastructure and zero environmental impact. Working directly beneath a sensitive and ecologically significant watercourse in the New Forest National Park, the project required careful planning and minimal equipment. Donkeys and cows strolled peacefully across the field during installation— symbolizing the zero-disruption achievement.
