Certificate in Septic System Operation & Maintenance

The Certificate in Septic System Operation & Maintenance is designed to provide learners with practical knowledge and technical skills required for the operation, inspection, maintenance, troubleshooting, cleaning, and safe management of septic tank and onsite wastewater treatment systems used in residential, commercial, institutional, rural, and remote facilities.

The program introduces the principles of onsite wastewater treatment, including septic tanks, inlet and outlet arrangements, baffles, effluent filters, distribution systems, drain fields, soakaways, inspection chambers, pumps, alarms, and associated components. Learners will develop an understanding of how wastewater is collected, settled, treated, distributed, and discharged safely within an onsite wastewater system.

The course emphasizes routine inspection, sludge and scum assessment, tank cleaning and desludging awareness, effluent monitoring, drain-field maintenance, pump and float-system inspection, leakage identification, odour control, blockage prevention, groundwater and surface-water protection, and system troubleshooting. Emphasis is placed on safe wastewater handling, hygiene, environmental protection, preventive maintenance, record keeping, and professional service practices.
