Civil Design Engineer - Water Industry

Transform water infrastructure across the UK Purpose and scope of the role

Tetra Tech’s Water Consultancy is seeking multiple Civil Design Engineers to support long‑term water industry frameworks across the UK, including major programmes in water and wastewater treatment plant design, river health, sewerage infrastructure and wider asset upgrades. You will contribute to outline and detailed designs, construction‑ready drawings and technical documentation for treatment works, pumping stations, rising mains, pipelines and site layouts.

Daily activities will include client engagement, feasibility and optioneering inputs, interdisciplinary coordination and delivery of technical outputs for multi‑million‑pound programmes within AMP8 and AMP
9. You will work in multidisciplinary teams, supporting the integration of civil design with structural, mechanical, electrical and ICA disciplines, and mentoring graduate engineers where required.

In the short term, you will deliver accurate and practical design packages that support procurement, construction and successful project outcomes. Over the medium term, you will take greater ownership of design work streams, improve technical efficiency and contribute to low‑carbon, resilient solutions for water and wastewater treatment and wider infrastructure projects. Longer term, you will help shape high‑quality design delivery across significant UK frameworks and support the development of other engineers in the team.

• Technical design proficiency — Produce robust outline and detailed civil designs, calculations and construction documentation to UK standards for water and wastewater treatment plant and associated infrastructure.
• Multidisciplinary coordination — Integrate civil inputs with structural, mechanical, electrical and ICA disciplines, contributing to coordinated design reviews and efficient delivery.
