The Opportunity

An exciting opportunity has arisen for an experienced Water Treatment Equipment Service & Installation Engineer to join a growing water treatment business, supporting an established customer base across the South of England.

This is a hands‑on, field‑based engineering role, suited to someone with strong practical experience in the servicing, maintenance, fault‑finding, repair, installation and commissioning of commercial and industrial water treatment equipment.

The ideal candidate will be a technically capable engineer who enjoys diagnosing problems, getting equipment back up and running and delivering new installations.

This is an equipment‑focused engineering position rather than a traditional water hygiene role, so experience in monitoring and sampling alone will not be sufficient.

The Role

• Service, maintain, fault‑find and repair commercial and industrial water treatment equipment.
• Install and commission new and replacement water treatment systems.
• Diagnose mechanical, electrical and control‑related faults.
• Carry out planned preventative maintenance and emergency repairs.
• Complete accurate service reports, commissioning documentation and job records.
• Identify opportunities for equipment repairs, replacements and system improvements.

About You

• A minimum of 3 years' experience within commercial or industrial water treatment equipment – especially with servicing water softeners, chemical dosing pumps, RO, UV disinfection etc.
• Proven experience servicing, maintaining and repairing water treatment equipment.
• Strong mechanical and practical engineering skills.
• Good electrical and control fault‑finding capabilities.
• Experience servicing and rebuilding commercial water softener valves.
• Experience installing and commissioning dosing and water treatment equipment.
• A full UK driving licence.
