About the Role
Water sustains communities, ecosystems, and life itself. At Thames Water, we supply over 10 million customers with around 2.6 billion litres of water every day — much of it drawn from the ground beneath our feet. To protect this essential source, we’re looking for a Groundwater Resources Manager to lead our talented team and shape the long-term direction of groundwater management across our region.

As the Groundwater Resources Manager, you will set the vision for how Thames Water manages, protects, and optimises its groundwater resources. Leading a team of four specialists, you’ll guide technical priorities, empower your team to deliver high-quality work, and ensure alignment with organisational, environmental, and regulatory goals. Your leadership will drive the sustainable use of our aquifers, the protection of groundwater quality, and the safeguarding of the chalk rivers that are central to our environment and heritage.

Key responsibilities include:
- Shaping and delivering the long-term vision for groundwater resource management at Thames Water, ensuring alignment with wider business, regulatory, and environmental priorities.
- Leading and developing a high-performing team, providing direction, coaching, and support to enable excellence in technical and strategic groundwater work.
- Providing senior technical input into strategic documents such as the Water Resources Management Plan, Drought Management Plan, and regulatory submissions influencing regional water security.
- Overseeing analysis of key datasets (e.g., pumping tests, CCTV surveys, monitoring networks), ensuring robust insights that inform operational decisions and investment planning.
- Identifying optimisation opportunities across sources and assets to reduce environmental risks, strengthen drought resilience, and improve performance.
- Championing cross-functional collaboration with colleagues in Operations, Engineering, Asset Management, and Environment to translate groundwater insights into practical actions.
- Maintaining a strong connection to the field by supporting team members in site visits to groundwater sources, treatment sites, and monitoring locations to deepen understanding of assets and local conditions.
