Thames Water has recently completed a £16.8m project to upgrade 2.4km of ageing trunk main in Fortis Green, North London.
The work was carried out in collaboration with Barhale and was part of Thames Water’s AMP7 (2020-2025) Trunk Main programme to improve resilience across its clean water supply.
The investment is part of Thames Water’s ongoing improvements to its network, with over £20bn planned to be invested between 2025-2030 across both its water and wastewater infrastructure.
Mark Taylor, Director of Delivery, London Infrastructure, Thames Water said:
“Our purpose is to deliver life’s essential service, so our customers, communities and the environment can thrive.
“We’re seeing the effects of population growth and climate change are putting increased pressure on our water pipes across the capital and we have a long-term commitment to improving infrastructure resilience, environmental performance, and service to customers as we plan to invest more than £20 billion by 2030.”
The upgrade was completed using a combination of micro-tunnelling and open cut trenching techniques. The project also moved the existing pipeline away from the A406 North Circular which will help limit traffic delays in the future should repairs and maintenance need to take place.
Shane Gorman, Water Director (Southern Region), Barhale said:
“Thanks to our extensive modelling and changes to the reference design we have been able to improve the capacity and the dynamic flow performance of the pipeline. This project is a strong example of how strategic engineering and early collaboration can deliver sustainable, high-value outcomes.”
