WPI exam, class match under review
Program authority: Tennessee Department of Environment and Conservation, Division of Water Resources - Board of Water and Wastewater Operator Certification; administered through Fleming Training Center
Local levels: Grade I, Grade II, Grade III, and Grade IV Water Treatment Plant Operator; Small Water System Operator
The state explicitly identifies standardized WPI water-treatment examinations and lists Grade I–IV standardized outlines. Small Water System is a separate credential, with a Very Small Water System outline listed under standardized criteria. Numerical shared routing remains unverified because the underlying treatment PDFs were not opened to confirm local Grade-to-WPI Class correspondence; this is not evidence of customized exams.
No state-matched course is linked for this stream yet.
Says references are approved for ‘WPI’s standardized water treatment operator examinations’; under ‘WPI Standardized Need-to-Know Criteria’ lists Very Small Water System and Water Treatment Operator Grades I–IV.
Rule .07(1)(a)–(e) names Grade IV, III, II, and I Water Treatment Plant Operator and Small Water System Operator. Rule .04 requires certification for persons in direct charge.
Exam route under review
Program authority: Tennessee Department of Environment and Conservation, Division of Water Resources - Board of Water and Wastewater Operator Certification; administered through Fleming Training Center
Local levels: Grade I, Grade II, Grade III, and Grade IV Wastewater Treatment Plant Operator; Biological/Natural System Operator
Partial verification: the authority expressly identifies WPI standardized wastewater-treatment exams for Grades I–IV. Biological/Natural System has a separate Tennessee outline, but its exam provider and standardized/customized/state-authored status are not established. Overall stream is therefore marked unverified rather than assuming uniform standardized scope or a confirmed mixed system. Numbered shared levels are withheld because treatment Grade-to-WPI Class PDFs were not checked.
No state-matched course is linked for this stream yet.
Explicitly says ‘WPI’s standardized wastewater treatment operator examinations Grades I - IV’; separately lists Biological/Natural System Operator with its own BNS Need-to-Know Criteria.
Separate outline revised January 23, 2009 covers lagoons, septic tanks, effluent disposal/NPDES permits, disinfection, support equipment, laboratory tests, and general operating knowledge; does not identify a WPI standardized or customized exam.
Rules .08 and .09 distinguish Biological/Natural systems from Grades I–IV wastewater treatment; .09(1)(e) separately names Biological/Natural System Operator.
Shared WPI prep
Program authority: Tennessee Department of Environment and Conservation, Division of Water Resources - Board of Water and Wastewater Operator Certification; administered through Fleming Training Center
Local levels: Grade I and Grade II Water Distribution System Operator; Small Water System Operator also serves qualifying small distribution systems
The authority explicitly identifies standardized WPI distribution exams. Its local Grade II link opens the Standardized Water Distribution Operator Class II outline, verifying Grade II → Class II. Grade I is listed, but its PDF correspondence was not checked within the source cap. No local distribution Grades III–IV are offered in the governing classifications. Small Water System is separate, not a numbered shared level.
Identifies ‘WPI’s standardized water distribution operator examinations’ and links Water Distribution Operator Grade I and Grade II under standardized criteria.
The state’s Grade II link opens ‘Water Distribution Operator Class II Certification Exam’; the document says it reflects only the Standardized Class II exam and distinguishes customized services.
Rule .07(1)(f) names Grades I & II Water Distribution System Operator; .06(3)(d) states Small Water Systems classification also serves as distribution certification for qualifying systems.
Shared WPI prep
Program authority: Tennessee Department of Environment and Conservation, Division of Water Resources - Board of Water and Wastewater Operator Certification; administered through Fleming Training Center
Local levels: Grade I and Grade II Wastewater Collection System Operator
Collection is separately supported by wastewater-collection evidence, not inferred from drinking water. The local Grade II link opens the Standardized WPI Wastewater Collection Operator Class II outline, verifying Grade II → Class II. Grade I is listed but its PDF mapping was not checked. Certification is mandatory for persons in direct charge, not merely voluntary. Rules allow Grade I wastewater-treatment or Biological/Natural certification to serve certain Grade I collection systems with fewer than fifteen service connections; that is not proof of shared collection exam content.
Identifies ‘WPI’s standardized wastewater collection operator examinations’; standardized criteria links are Wastewater Collection Operator Grade I and Grade II.
The state’s Grade II link opens ‘Wastewater Collection Operator Class II Certification Exam’; expressly says the outline reflects only the Standardized Class II exam, not customized exams.
Rule .09(1)(f) names Grades I & II Wastewater Collection System Operator; .04(2) requires a qualifying certificate for persons in direct charge of collection systems; .08 provides limited small-collection cross-credential recognition.
