Core Responsibilities

Primary Functions

Operate and monitor unit processes in wastewater and waste treatment plants (primary settling, biological reactors, clarifiers, filtration, disinfection) to maintain optimal performance and meet effluent permit limits.
Continuously monitor process control systems and SCADA displays, interpret alarms and trends, and take corrective actions such as adjusting aeration, chemical feed rates, or sludge wasting to stabilize treatment performance.
Collect, prepare, and perform accurate laboratory analyses including BOD, TSS, pH, ammonia, chlorine residual, dissolved oxygen, conductivity and other permit-required tests; log results and notify supervisors of excursions.
Adjust and calibrate chemical dosing systems (coagulants, flocculants, disinfectants, pH correction) based on lab results, flow conditions and operational goals while complying with safety and storage protocols.
Perform routine and preventive maintenance on pumps, motors, blowers, valves, mixers and associated mechanical equipment to minimize downtime and extend equipment life; coordinate with maintenance team for repairs.
Conduct inspections of tanks, clarifiers, pumps, piping, instrumentation, and structural components; document deficiencies and ensure corrective work orders are initiated and closed in the CMMS.
Handle sludge management tasks including sludge thickening, dewatering, hauling coordination, biosolids stabilization and disposal consistent with regulatory and facility requirements.
Maintain accurate operational logs, shift reports, permit compliance documentation, and daily/monthly regulatory reports for submission to environmental agencies when required.
Troubleshoot process upsets and mechanical failures, develop corrective action plans, and execute temporary or permanent fixes while escalating complex issues to engineering or management.
Start up and shut down process trains, pumps and chemical feed systems during planned maintenance, emergency response, or seasonal changes following lockout/tagout (LOTO) and written procedures.
Respond to alarms and after-hours emergencies, diagnose root causes, perform emergency repairs or adjustments, and document incident reports and follow-up corrective actions.
Operate and maintain odor control systems, chemical feed points, and containment measures to minimize community and workplace impacts.
Ensure all work is performed in accordance with safety rules, confined space entry procedures, respiratory protection programs, and OSHA standards; lead or participate in safety briefings.
Verify and maintain inventory of spare parts, treatment chemicals, and consumables; place purchase requests and coordinate deliveries to prevent stockouts that affect operations.
Liaise with environmental compliance staff and regulatory agencies during inspections, sampling events and permit renewals to ensure transparency and compliance.

Secondary Functions

Assist process engineers and lab staff with pilot studies, process improvement projects and capital improvement input to improve plant capacity, energy efficiency, and permit attainment.
Enter and maintain performance data in computerized maintenance management systems (CMMS), SCADA logs, and plant dashboards to support data-driven decision making.
Participate in training new operators and cross-training team members on equipment operation, safety protocols, and laboratory procedures to maintain a resilient operations team.
Support routine calibration and preventative care for field instruments (e.g., DO probes, turbidity meters, pH sensors) and coordinate calibration certificates for audit readiness.
Perform confined space entries, hot work permits, and other controlled operations with appropriate attendants, permits, and rescue planning in place.
Prepare sampling kits, schedule and coordinate third-party analytical lab shipments, and review external lab results for consistency and anomalies.
Contribute to the facility’s continuous improvement program by recommending process or maintenance changes, tracking outcomes, and documenting lessons learned.
Participate in emergency response drills (spill response, backup power loss, severe weather) and update emergency procedures based on drill outcomes and real incidents.
Maintain site housekeeping, containment measures and spill prevention controls to ensure a clean, compliant and safe plant environment.

(Combined primary and secondary functions provide a robust set of responsibilities commonly found across municipal and industrial waste treatment operator job descriptions.)
