ABC Wastewater Collection Class II case studies

The ABC Wastewater Collection Systems Operator Class II certification is a voluntary, third-party credential for people who operate and maintain sanitary sewer collection systems. It sits at the intermediate level: above entry-level Class I and below the advanced Class III/IV grades, so it assumes you already know how a collection system is put together and can work without constant supervision. Candidates typically include collection system technicians, maintenance and repair crews, lift station operators, and utility staff who want a portable proof of competence that travels beyond their own employer. The exam is multiple choice and samples broadly rather than deeply, drawing on system operations and maintenance, sewers and lift stations, safety and confined space entry, flow and hydraulics, inspection and rehabilitation, regulations and reporting, calculations, grease and odor control, and recordkeeping. The ABC Wastewater Collection Class II case studies are 5 cases and about 1,664 words.
