Mechanical Project Engineer

As a Project Engineer within the Thames Valley Delivery Office, you'll play a vital role in delivering projects that improve both water and wastewater treatment services across the region. Working on some of Thames Water's most important infrastructure, you'll help modernise treatment plants, enhance environmental performance, increase resilience, and ensure we continue to provide safe, reliable services to millions of customers.

You'll be involved throughout the project lifecycle, from technical reviews, feasibility studies and design development through to construction, commissioning and handover. Working across a diverse portfolio of schemes, you'll help improve drinking water quality, increase treatment capacity to support growing communities, enhance wastewater treatment processes, reduce storm overflows, improve effluent quality, and protect local rivers and ecosystems.

This is an exciting opportunity to contribute to projects that safeguard the environment, support regulatory commitments, and future-proof critical water and wastewater assets for generations to come.
