Drainage Operative - Sewer Depth Monitoring

Purpose and Scope of the Role

You will install, commission and maintain sewer depth monitors, flow‑survey sensors and associated telemetry across the local wastewater network. Working in permanent two‑person teams, you will complete site assessments, routine calibrations, fault diagnosis and digital job‑sheet reporting.

Training is provided; health and safety and confined‑space procedures are integral to daily operations.

In the short term you will deliver reliable installations and accurate survey data that support operational decision‑making. Over the medium term you will develop technical troubleshooting, telemetry and commissioning skills, taking responsibility for increasingly complex sites. Longer term the role offers career progression into team leadership, field supervision or instrumentation and telemetry specialist roles within Tetra Tech, with access to formal training and on‑the‑job development.

• Fault diagnosis and problem solving – Ability to identify and resolve issues with sensors, telemetry and power supplies on site, escalating complex faults to engineers or project managers.
• Communication and reporting – Clear verbal and written skills to complete digital job sheets, communicate with project teams and liaise professionally with clients.
• Physical resilience and teamwork – Physically fit and willing to work outdoors in all weather; works effectively in a two‑person team to meet deadlines and project objectives.

Expected: full manual driving licence; basic IT literacy; demonstrable experience or interest in wastewater, utilities or field instrumentation. Training in telemetry, confined‑space entry and specific equipment will be provided.

Desirable: confined‑space certification, previous flow‑survey experience and basic electrical or telemetry training.

This is a 40‑hour, Monday‑Friday role based in Brentford with occasional night shifts and periods away as project needs dictate. Expect primarily on‑site work; office or admin days are occasional for reporting and team meetings.
