Ready to help shape the UK’s water future? 

\n\n\n

We’re looking for a motivated and ambitious Assistant Project Manager, minimum 2 years of major infrastructure experience, to support one of the largest and most complex infrastructure programmes the UK water sector has seen in decades. 

\n\n\n

If you’re passionate about delivering major, complex projects in the water or infrastructure sector, thrive on challenge and change, and are ready to take accountability for shaping critical infrastructure, this is your chance to make a lasting impact.    

\n\n\n

The Reservoirs Programme focuses on two new, large-scale raw water reservoirs — the Fens Reservoir and the Lincs Reservoir — along with all the associated infrastructure.
