HS2 is Britain’s largest infrastructure project, designed to connect London and Birmingham via a high-speed rail network. It is the first new intercity railway built north of London in over a century and represents the most significant rail investment in the UK’s history. Spanning 140 miles, Phase 1 includes four new stations, two depots, 32 miles of tunnel, and 179 bridges, with trains reaching speeds of up to 225 mph.
WJ has been contracted by all of HS2’s construction partners across the entire route, providing expert water management solutions at 37 work sites.

With 29 contract packages delivered across multiple sites, WJ has played and continue to play a crucial role in maintaining safe working conditions and optimising construction timelines.
