EVERYTHING YOU NEED TO KNOW

As a Water Treatment Scientist, you’ll play a key role in either our Groundwater or Surface Water Treatment Process team, providing technical expertise across a portfolio of sites.

You’ll take ownership of process performance at your sites - analysing trends, identifying risks, and driving improvements - to ensure we consistently deliver safe, high quality water to our customers. 

This is a hands-on, practical role working both on operational sites and in the office. You’ll regularly travel between sites (car allowance provided), with the Surface Team roles including participation in a paid out-of-hours standby rota.

  • Supporting optimisation of treatment processes to improve chemical and energy efficiency

  • Completing Drinking Water Safety Plan (DWSP) assessments and reducing risk

  • Producing clear, evidence-based technical reports and recommendations

  • Working closely with site teams, providing practical, hands-on process support

  • Contributing to capital investment and improvement programmes alongside Process Design Engineers

  • Supporting commissioning and integration of new or upgraded assets

  • Driving compliance performance (e.g. CRI / EPA) and process resilience

  • Sharing best practice, lessons learned, and developing capability across the business


You’ll also play a key role in incident response and recovery, helping coordinate technical actions and restoring performance safely and efficiently.

 

 

 

 

WHAT WE’RE LOOKING FOR

  • A degree (or equivalent, including operational experience) in a scientific or engineering discipline

  • A logical, analytical mindset with the ability to interpret complex data

  • Confidence to challenge decisions constructively and influence outcomes

  • Excellent communication skills across a range of stakeholders

  • Knowledge of systems such as SAP, SCADA/ESCADA, Cognos, QUIS

  • Experience in root cause analysis and incident management

  • Understanding of hydraulics or groundwater processes (role dependent)

We seek people who get involved, want to be part of something bigger, and make a difference because they care.
