• Technical Support: Partnered directly with maintenance supervisors and mechanical
engineers to fulfill industrial work orders and system optimizations.
• Tool & Material Management: Handled, organized, and tracked essential mechanical tools,
spare parts, and maintenance materials, logging usage for team lookup and future supervisor
reference.
• Equipment Assembly: Assisted in dismantling, overhauling, aligning, and reassembling plant
machinery components and pipe fittings.

• Operated and monitored Reverse Osmosis, De-ionization, UV/Ozone purification and
boiler water systems via HMI/SCADA control systems, ensuring safe start-up, shutdown
and optimum permeate water quality.
• Monitored, calibrated and maintained Pressure Gauges, Conductivity Meters, pH Meters
and chemical dosing controllers, conducting chemical analysis using portable meters
for cross-verification and coordinating dosing rate adjustments.
• Reviewed RO product normalization charts daily and carried out periodical CIP (Clean
In-Place) processes, SDI tests and conductivity probe checks to maintain plant
efficiency.
• Assisted the maintenance team with membrane replacement and pressure vessel
cleaning, and inspected feed/high-pressure pumps, electrical panels, instrumentation
and valves to ensure flawless plant operation.
• Performed routine back-washing of carbon and sand filters; routine replacement of
micro-filters.
• Managed recharging of softener, Strong Acid Cation (SAC), Strong Base Anion (SBA)
and Mixed Bed ion exchange units, ensuring required chemicals were always in place.
• Collected water samples for laboratory analysis, interpreted results and adjusted
treatment processes accordingly.
• Prepared and maintained accurate maintenance logs, calibration records and
regulatory compliance reports.
• Trained new staff on safety procedures and plant equipment operation.

Key Achievements:
• Participated in over 60% of all repairs, borehole operations and meter reading activities
across the plant.
• Successfully coordinated operation, maintenance and repair of water treatment
equipment over 15+ years with zero major compliance failures.
• Responded to a neighbouring community fire emergency, saving up to 75% of tools,
materials and personal items.
• Consistently ensured timely distribution of quality water to all sections in accordance
with required standards.
• Supported troubleshooting of mechanical failures, reducing equipment downtime and
optimizing treatment efficiency.
• Conducted routine checks on chemical dosing equipment and adjusted chemical feed
rates to consistently maintain water purity and treatment quality.
• Performed CIP (Clean-In-Place) procedures for the RO plant and consistently reported
quality, environmental and safety hazards in line with management system processes.

Cross-Section Coordination: Effectively managed the supply and distribution lines of
treated water across the facility, collaborating closely with supervisors in the water bottling,
boiler, and distillery sections to meet their specific water quality and volume requirements. Staff Onboarding Designated by plant management to train and mentor new
technicians, delivering clear instructions on operating protocols, system controls, and
workplace safety standards. Technical Presentation & Site Visits: Served as the key on-site representative to welcome
and guide management-appointed corporate visitors, explaining the layout, machinery, and
daily technical processing functions of the plant.
• Parameter Monitoring & Logging: Performed timely, scheduled sampling and testing of
water quality parameters, maintaining exact log sheets of pH, TDS, and conductivity to ensure
operational limits were maintained.
• Meter Inspections: Conducted routine physical rounds across the plant to record water
meter readings, effectively tracking total volumetric consumption and identifying hidden
system leaks or drop-offs.
• Chemical Inventory & Reporting: Actively tracked daily and weekly chemical usage rates
across the plant; prepared detailed inventory reports on remaining chemical balances to
prompt timely restocking and ensure process continuity.
• Filtration Operations: Managed and performed routine backwashing and rinsing operations
for rapid sand filters and activated carbon filters to prevent media fouling and ensure optimal
flow rates.
• Micro-Filtration Management: Systematically monitored differential pressure across
filtration lines and executed the routine replacement of micro-filters to safeguard water clarity
and downstream equipment.
• Water Production Management: Managed plant operations to successfully process and
treat industrial Boiler water, De-ionized (DI) water for production, and high-standard
bottled/mineral water lines.
• Spare Parts Records & Logbooks: Actively documented and cross-referenced mechanical
spare parts, gaskets, bearings, and seals utilized during overhauls to maintain an accurate
reference log for future maintenance requirements.
