Work Integrated Learning at Ekhurhuleni Water Care Company (2025-10 – 2026-03)

Conducted routine wastewater treatment plant operations and monitoring

• Conducted routine wastewater treatment plant inspections to monitor flow conditions, equipment performance, and ensure operational and safety compliance.
• Collected and analysed wastewater samples to support treatment efficiency and maintain compliance with regulatory water quality standards.
• Monitored key operational and water quality parameters including Suspended Solids (SS), Dissolved Oxygen (DO), Oxidation Reduction Potential (ORP), Mixed Liquor Suspended Solids (MLSS), influent colour, effluent clarity, and free chlorine.
• Performed wastewater process control calculations such as Primary Settling Tank (PST) efficiency, Sludge Age (SRT), Sludge Volume Index (SVI), and sludge wasting rate to support plant performance optimisation.
• Monitored biological treatment processes and sludge settling behaviour, interpreting microscopic observations and SVI results to assist in process control decisions.
• Perfomed sludge handling, dewatering, and drying operations, including exposure to sludge management processes.
• Monitored chemical dosing processes and operational conditions to support stable plant performance.
• Recorded operational readings, laboratory results, and plant observations accurately in daily logbooks and operational records.
• Participated in shift handover communication, reporting abnormal plant conditions and supporting operational continuity.
• Prepared production reports, operational documentation, and plant performance records.
• Monitored mass balance monitoring and Green Drop compliance processes in line with regulatory requirements from the Department of Water and Sanitation.
• Maintained plant housekeeping standards to ensure a safe, organised, and efficient working environment.
