Thames Tunnel

We are helping to construct the west section of the Thames Tunnel – London’s new ‘super sewer’.

Running underneath the River Thames, the new tunnel will ensure the capital’s sewerage system is fit to support its projected population for at least the next 100 years. It will also tackle the issue of discharges of untreated sewage that currently enter the River Thames on a regular basis.

Working in a three-way equal joint venture alongside Morgan Sindall and BAM Nuttall, we will deliver the £416 million, seven kilometre ‘West’ section of the overall 25km Thames Tunnel.

From Acton in West London to Wandsworth in South West London, the project will incorporate seven separate work sites along the route. Works will include design, construction, commissioning and maintenance for a two to five year period following construction completion.

This unique infrastructure project, which is the largest ever undertaken by the UK water industry, is another example of the part we are playing in 21st Century engineering.

Thinking locally

Using Building Information Modelling (BIM), we will test and simulate construction before works start on site for safe and efficient delivery. A large percentage of project materials will be transported down the river to ease road congestion, emissions and disruption throughout the duration of the project.

The overall Thames Tideway Tunnel scheme will create more than 4,000 direct and indirect jobs at the peak of construction. Throughout the project, we will engage with local businesses and SMEs, providing local job opportunities including 50 new apprenticeships demonstrating our commitment to inspire and upskill a new generation.
