Senior Associate – Wastewater

This is a unique opportunity to work directly for the regulator, influencing how billions of pounds are invested across the water sector to deliver better outcomes for customers, communities, and the environment. You’ll have a national view of the industry – shaping strategy, assessing performance, and helping to set the standards that drive long-term improvement.

The Role

Working within the wastewater and bioresources cost assessment team, the successful candidates will:

• Analyse and assess company investment plans, focusing on wastewater treatment, storm overflows, drainage management, and sludge treatment.
• Engage with water companies, regulators, and stakeholders to monitor performance and value delivery.
• Apply data analysis, modelling, and technical expertise to support evidence-based decisions.
• Contribute to policy development, process design, and expenditure tracking for major environmental and infrastructure programmes.

About You

We’re looking for professionals with:

• Strong technical experience in wastewater treatment, sewerage networks, or bioresources.
• A relevant degree (engineering, science, or data analysis) or equivalent professional experience.
• Proven analytical and data interpretation skills to support decision-making.
• Excellent written and verbal communication, able to convey complex information to technical and non-technical audiences.
• A proactive, collaborative mindset and the ability to work effectively across multidisciplinary teams.

Previous experience could include wastewater hydraulic modeller, engineer, scientist, asset manager, or data analyst.
Experience in asset management, capital programme planning, or environmental resilience would also be advantageous.

Benefits

Our client offers a highly flexible, hybrid working environment alongside:

• 25 days’ annual leave (increasing to 30 days with each year of service) plus bank holidays and privilege days
• Generous employer pension contributions of up to 28.97%
• Professional membership fees paid
• Volunteering days, wellbeing support, and learning & development opportunities

This is an outstanding opportunity to influence the future of the UK’s water and wastewater sector from within the regulator itself – shaping the policies, frameworks, and investment decisions that deliver lasting environmental and public value.
