Plumber — Water Supply, Wtp/Stp & Pressure Systems

JOB SUMMARY

The Plumber will maintain, inspect, and repair the site's full-scope plumbing and water infrastructure, spanning general pipework and fixtures, borehole and pressure/pumping systems, water storage tanks, and the Water Treatment Plant (WTP) and Sewage Treatment Plant (STP). The role requires a technician confident working independently on routine PPM and fault-finding across both general plumbing and specialist treatment-plant systems, in a live, 24/7, high-footfall environment.

KEY RESPONSIBILITIES

• Carry out scheduled PPM and repairs on general plumbing systems: pipework, fixtures, fittings, water heaters, and drainage across all zones.
• Maintain and monitor borehole, pumps, pressure management systems, and water storage tanks to ensure consistent water supply.
• Support day-to-day operation and maintenance of the Water Treatment Plant (WTP), including filtration, dosing, and water quality checks.
• Support day-to-day operation and maintenance of the Sewage Treatment Plant (STP), including biological system checks, chemical dosing, and effluent quality monitoring.
• Diagnose and repair leaks, blockages, and pipework faults promptly to minimise disruption and water loss.
• Carry out routine water quality and compliance checks in line with regulatory requirements (e.g. NESREA/NAFDAC-aligned standards) and internal procedures.
• Maintain accurate maintenance logs, test results, and defect reports using the facility's CMMS/CAFM platform.
• Respond promptly to plumbing and water-system emergency call-outs, including out-of-hours where required.
• Follow safe isolation and permit-to-work procedures at all times, including safe handling of treatment chemicals; no bypassing of safety systems under any circumstance.
• Liaise with the Plumbing Lead/Chief Engineer on parts requisition, defect escalation, and PPM scheduling.

Requirements

REQUIREMENTS & QUALIFICATIONS

• OND/HND or Trade Certificate in Plumbing, Mechanical Engineering, Water/Environmental Engineering, or a related technical discipline.
• Minimum 3–6 years' hands-on experience in commercial/industrial plumbing, with exposure to pressure systems, pumps, and water storage infrastructure.
• Working knowledge of, or willingness to be trained on, WTP/STP operations — filtration, chemical dosing, and biological treatment processes.
• Basic understanding of water quality and effluent compliance requirements is an advantage.
• Comfortable working with a CMMS/CAFM system for logging maintenance activity (training provided if not previously used).
• Strong fault-finding and diagnostic skills, with a methodical, safety-first approach to work.
• Willingness to work shifts, be on standby/on-call, and respond to emergency call-outs outside normal hours.
• Good communication skills and the ability to work as part of a wider engineering team on a live operational site.
• Physically fit and able to work in plant-room/industrial environments, including confined spaces where applicable.
