Source check: 2026-10-04. Shared WPI courses are linked only where the standardized exam and class match are confirmed. Local grades may not equal WPI class numbers. Your authority's current documents control.
Exam route under review
Program authority: Utah Department of Environmental Quality, Division of Drinking Water
Local levels: Treatment Grade I (T1), Treatment Grade II (T2), Treatment Grade III (T3), Treatment Grade IV (T4)
Official DDW materials establish Utah-specific grade outlines and examination governance, but the opened sources do not explicitly establish whether the exams are state-developed, customized ABC/WPI, or standardized WPI. Do not route T1–T4 as verified shared WPI classes.
No state-matched course is linked for this stream yet.
The grade table explicitly lists Treatment Grade I (T1) through Treatment Grade IV (T4). Exam categories are Math, Operation and Maintenance, Pumps, Chemical Feed, Rules, and Safety and Security; separate basic and advanced treatment study guides are provided.
The Utah commission includes treatment and distribution representatives and makes decisions about 'what topics ... will be tested on' and program operation. This establishes local oversight, not explicit exam authorship or standardized WPI use.

Local levels: Small Lagoon System explicitly identified; current regular treatment grade names were not enumerated in the opened sources.
DWQ explicitly confirms standardized WPI exams for its wastewater program, including treatment. However, it separately identifies Utah's Small Lagoon System exam and a state-created outline without explicitly identifying that exam's provider or standardized/customized status. The entire treatment stream is therefore marked unverified rather than assuming a uniform exam system. Regular local-grade-to-WPI-class correspondence was not established.

'Utah’s Wastewater Operator Certification Program uses standardized exams produced by Water Professionals International (WPI),' formerly ABC. Separately: the program 'has also created Need-to-Know Criteria for Utah’s Small Lagoon System exam,' linking its 2025 criteria.
The page expressly addresses both 'wastewater treatment and collection exams' and states that examinations cover WPI Need-to-Know Criteria. It does not enumerate local grades or map them to WPI classes.

Local levels: Small System (SS); Distribution Grade I (D1), Distribution Grade II (D2), Distribution Grade III (D3), Distribution Grade IV (D4)
DDW explicitly lists SS and D1–D4 and supplies local examination outlines. The opened sources do not distinguish state-developed exams from customized ABC/WPI exams or confirm standardized WPI examinations. SS has a distinct outline and must not be treated as WPI Class I.
No state-matched course is linked for this stream yet.
The distribution table explicitly lists Small System (SS) and Distribution Grade I (D1) through Grade IV (D4). Basic Distribution applies to SS and D1–D4; Advanced Distribution applies to D3–D4.
Utah's commission determines examination topics and program operation; the page links R309-300 certification rules and operator certification policies but does not identify a standardized WPI exam.

Local levels: Current collection grade names not verified in the opened official sources.
Standardized WPI use is explicitly supported by DWQ's wastewater preparation page together with its collection-specific examination description - not by drinking-water evidence or PSI delivery. Shared levels remain empty because the opened sources did not establish local grade names and their correspondence to WPI Classes I–IV.
No state-matched course is linked for this stream yet.
The program explicitly 'uses standardized exams produced by Water Professionals International (WPI)' and says the relevant work experience includes 'collection and wastewater treatment.'
The state explicitly identifies wastewater 'treatment and collection exams' and their WPI Need-to-Know examination content.
Dedicated prep is not available or being sold yet.
