About the Role
Tetra Tech seeks Trainee Leakage Technicians for permanent, full-time roles to support regional leakage reduction programmes. You will work within multi-disciplinary teams including three-person site survey crews and office specialists, delivering leakage detection, monitoring, and repair activities across multiple regional contracts.

This operational and client-facing role is supported by full training, mentoring, and an allocated company van.
