Utah water operator certification

Reviewed 2026-07-29

Quick answer

How do I get certified as a water operator in Utah?

Utah splits certification across two DEQ divisions. The Division of Drinking Water certifies water treatment and distribution operators on a Small System through Grade 4 ladder, sized by population served, with exams through the Rural Water Association of Utah (RWAU). The Division of Water Quality separately certifies wastewater treatment and collection operators, Grade I through IV, exams through PSI, application $50 plus a roughly $106 PSI testing fee, renewal $75 every 3 years. Both sides offer reciprocity to operators certified elsewhere.

Certifying agency: Utah Department of Environmental Quality (DEQ): Division of Drinking Water (water) and Division of Water Quality (wastewater)

Apply through the relevant division: Division of Drinking Water for water treatment/distribution, Division of Water Quality for wastewater treatment/collection, each with its own exam application and fee.
Pass a 100-question, 70%-minimum exam within a 3-hour window, covering categories specific to the license grade.
Meet the minimum-qualifications table for the grade (R309-300-19 for drinking water), which trades education for required operating and direct-responsible-charge (DRC) experience.
Complete continuing education units (CEUs) before the 3-year certificate expires: drinking water grades scale from 2 CEUs (Small System, Grade 1, Grade 2) to 3 CEUs (Grade 3, Grade 4); wastewater grades scale the same way, 2 CEUs at Grade I-II and 3 CEUs at Grade III-IV.

Water treatment

SS: Small System , Systems serving 25 to 1,500 people (treatment) or 25 to 500 (distribution).
1: Grade 1 , Treatment: population 25-1,500 (population bands differ slightly between treatment and distribution).
2: Grade 2 , Population 1,501-5,000.
3: Grade 3 , Population 5,001-15,000.
4: Grade 4 , Population over 15,001.

Exam: 100 multiple-choice questions across 6 categories, 70% minimum, 3-hour time limit. Exams administered online year-round or on paper seasonally through the Rural Water Association of Utah (RWAU), not PSI.
Education minimum: Utah Admin. Code R309-300-19 Table 5 sets 4 alternate paths per grade, trading a 2-year associate degree, a high school diploma, or no high school diploma against a longer direct-responsible-charge (DRC) training period. At least half of the required unrestricted experience must be gained at the desired certification grade itself.
Experience minimum: Grade 4: associate degree path needs 2 years operational plus 2 years DRC training (4 total); HS-diploma path needs 4 plus 2 (6 total); no-HS-diploma paths need 4 plus 4 (8 total) or 5 plus 5 (10 total). Grade 3: associate or HS-diploma paths need 1 plus 1 (2 total); no-HS-diploma paths need 2 plus 2 (4 total) or 3 plus 3 (6 total). Grade 2 and Grade 1/Small System need no prior operational experience, only 1 to 3 years of DRC training depending on grade and path. Post-secondary education can substitute for up to half the experience requirement at Grades 3 and above, not at Grades 1-2.
Continuing education: 2 CEUs (20 contact hours) for Small System, Grade 1, and Grade 2; 3 CEUs (30 contact hours) for Grade 3 and Grade 4. One CEU equals 10 contact hours of approved instruction. The CEU accumulation period begins January 1 of the year after passing the exam.
Renewal cycle: 3 years
Reciprocity: The Division of Drinking Water accepts a Reciprocity Request application from operators certified in another state; dual-certified operators may also request one certificate's expiration date shift by a year to unify renewal cycles across a Utah and out-of-state or cross-discipline certificate.

Certificates expire every 3 years on December 31, with a grace period through the following June 30 for renewal or reinstatement. Exams are proctored through RWAU rather than the PSI network wastewater uses, a genuine administrative difference between Utah's two divisions.

Water distribution

SS: Small System , Distribution systems serving 25 to 500 people.
1: Grade 1 , Population 501-1,500.
2: Grade 2 , Population 1,501-5,000.
3: Grade 3 , Population 5,001-15,000.
4: Grade 4 , Population over 15,001.

Exam: Same RWAU-administered exam format as water treatment, a distribution-specific exam.
Continuing education: Same CEU schedule as water treatment: 2 CEUs at Small System/Grade 1/Grade 2, 3 CEUs at Grade 3/Grade 4.
Renewal cycle: 3 years
Reciprocity: Same Reciprocity Request process as water treatment.

Distribution population bands run slightly lower than treatment at the Small System and Grade 1 tiers (500 and 1,500 versus treatment's own bands), reflecting that a pure distribution system needs less complexity to reach the same grade.

Wastewater treatment

I: Grade I , Entry-level wastewater treatment certification.
II: Grade II , Requires documented experience beyond Grade I.
III: Grade III , Higher CEU requirement, 3 CEUs per cycle.
IV: Grade IV , Highest treatment grade, 3 CEUs per cycle.
USLS: Utah Small Lagoon System , A dedicated mandatory certification for small lagoon-based treatment systems, alongside the Grade I-IV ladder.

Exam: 100 to 110 multiple-choice questions on Need-to-Know Criteria, computer-based through PSI (testing centers in Salt Lake City, Cedar City, St. George, Ogden, plus live remote proctoring) or paper-based seasonally. 30-day waiting period required between exam attempts; exam applications are valid 6 months.
Application / certification fee: $50 computer-based exam application fee plus a roughly $106 PSI testing-center fee; $200 for a paper-based exam (effective July 1, 2024).
Continuing education: 2 CEUs required for renewal at Grade I and II; 3 CEUs at Grade III and IV, earned during the 3-year period before the certificate expires.
Renewal cycle: 3 years
Reciprocity: The Division of Water Quality offers reciprocity to operators certified in another state, at a $200 reciprocity fee, higher than the standard renewal fee.

Wastewater treatment is administered by the Division of Water Quality, a separate DEQ division from drinking water's Division of Drinking Water, with its own exam provider (PSI, not RWAU), its own fee schedule, and its own reciprocity fee. Certificates expire every 3 years on December 31, with reinstatement possible within 1 year of expiration for a $55-per-month fee (up to 3 months).

Wastewater collection

I: Grade I , Entry-level collection system certification.
II: Grade II , Requires documented collection-system experience beyond Grade I.
III: Grade III , Higher CEU requirement, 3 CEUs per cycle.
IV: Grade IV , Highest collection grade, 3 CEUs per cycle.

Exam: Same PSI-administered exam format as wastewater treatment, a collection-specific exam per grade.
Application / certification fee: Same fee structure as wastewater treatment: $50 plus roughly $106 PSI fee for computer-based, $200 for paper-based.
Continuing education: 2 CEUs at Grade I-II, 3 CEUs at Grade III-IV, same schedule as wastewater treatment.
Renewal cycle: 3 years
Reciprocity: Same $200 reciprocity fee and process as wastewater treatment, through the Division of Water Quality.

Collections is a mandatory classification alongside wastewater treatment; Utah also offers voluntary Laboratory Analyst, Biosolids Land Applier, and Plant Maintenance Technologist certifications through the same Division of Water Quality program, outside the discipline scope covered here.

Utah is a genuine two-agency split: drinking water and wastewater certification are run by two different DEQ divisions, with different exam providers, different fee schedules, and different reciprocity fees, even though both use a similar grade structure underneath.

Two divisions, two exam providers

The Division of Drinking Water certifies water treatment and distribution operators on a Small System through Grade 4 ladder, sized by population served, with exams proctored through the Rural Water Association of Utah (RWAU), either online year-round or on paper seasonally at spring (southern Utah) and fall (northern Utah) conferences. The Division of Water Quality separately certifies wastewater treatment and collection operators on a Grade I through IV ladder, with exams administered through PSI at fixed testing centers or via live remote proctoring. Both ladders run 100-plus multiple-choice questions with a 70% passing threshold and a 3-hour limit, but the administering organization, and the fee you pay to sit the exam, genuinely differ by discipline.

	Drinking water (DDW)	Wastewater (DWQ)
Grades	Small System, 1, 2, 3, 4	I, II, III, IV
Exam provider	RWAU	PSI
Exam application fee	Not published in dollar terms; paid via online portal	$50 (computer) + ~$106 PSI fee, or $200 (paper)
Renewal cycle	3 years, expires Dec 31	3 years, expires Dec 31
Reciprocity fee	Reciprocity Request (no separate fee schedule published)	$200

Education trades against direct-responsible-charge experience

Utah’s minimum-qualifications table (R309-300-19 for drinking water) offers 4 alternate paths at most grades, trading a 2-year associate degree, a high school diploma, or no diploma at all against a longer period of direct-responsible-charge (DRC) training. At Grade 4, for example, an associate degree plus 2 years of operational experience plus 2 years of DRC training clears the bar (4 years total), while an operator without a high school diploma needs up to 5 years operational plus 5 years DRC (10 years total). At least half of the required unrestricted experience must be earned at the grade actually being sought, not just at a lower grade.

Continuing education scales with grade on both sides

Both divisions use the same CEU pattern: lower grades need 2 CEUs (20 contact hours) per 3-year cycle, higher grades (Grade 3/4 water, Grade III/IV wastewater) need 3 CEUs (30 contact hours). One CEU equals 10 contact hours of approved, reviewed instruction, and the clock starts January 1 of the year after passing the certifying exam.

Moving to or from Utah

The Division of Drinking Water accepts a Reciprocity Request from operators certified elsewhere, and dual-certified operators can align a Utah certificate’s expiration date with an out-of-state or cross-discipline certificate to simplify renewal tracking. The Division of Water Quality’s wastewater program charges a flat $200 reciprocity fee, notably higher than its own $75 standard renewal fee. See reciprocity between states for how this compares generally.
