Kansas water operator certification

Reviewed 2026-07-29

Quick answer

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

Kansas certifies water and wastewater operators through KDHE using a points system, not a fixed experience ladder: Small System needs 12.5 points and 6 months of experience, up to Class IV needing 18 points and 2 years. The exam fee is $25, certificates renew every two years for a $20 fee, and continuing education runs 5 hours for Small System operators up to 10 hours for Class I through IV.

Certifying agency: Kansas Department of Health and Environment (KDHE), Public Water Supply section

Points-based qualification: experience, education, and approved training all convert to points, and each class needs a minimum point total plus a minimum experience floor
$25 examination fee, submitted with the exam application at least 3 to 4 weeks before the deadline (a hard 2-week minimum applies)
Water and wastewater are certified on parallel Small System through Class IV tracks; KDHE's public certification materials do not describe a separate distribution-only credential apart from the water operator track
Certificates renew every two years with a $20 renewal fee and mandatory training hours; an operator can track hours and renewal status through KDHE's CertTracker system

Water treatment

SS: Small System , 12.5 points required, minimum 6 months of qualifying experience.
I: Class I , 13 points required, minimum 1 year of qualifying experience.
II: Class II , 14 points required, minimum 1 year of qualifying experience.
III: Class III , 16 points required, minimum 2 years of qualifying experience.
IV: Class IV , 18 points required, minimum 2 years of qualifying experience.

Exam: State-administered exam through KDHE; applications accepted first-come, first-served against testing-site capacity limits
Education minimum: A high school diploma or GED is required to sit for any class. Beyond that, KDHE uses a combined points system (see experience below) rather than a separate fixed education table; points come from a mix of documented experience, education, and completed approved training, detailed in KDHE's "Operator Certification Education, Training, and Experience Requirements" brochure.
Experience minimum: Small System: 6 months minimum plus 12.5 total points. Class I: 1 year minimum plus 13 points. Class II: 1 year minimum plus 14 points. Class III: 2 years minimum plus 16 points. Class IV: 2 years minimum plus 18 points. Applicants must also own or be employed by a water supply system or wastewater facility to apply.
Application / certification fee: $20 renewal fee every two years; a certificate that lapses can be reinstated within two years by completing the missed training hours and paying a reinstatement fee
Exam fee: $25 examination fee, submitted with the application
Continuing education: Small System operators: 5 hours of approved training every two years. Class I through IV operators: 10 hours every two years. Training applicable to both water and wastewater (such as pump maintenance) is split between the two credits unless the operator specifies otherwise.
Renewal cycle: 2 years

KDHE's public certification FAQ and document library name only a single water operator track (Small System through Class IV) without a separate distribution-only certificate. Distribution work at a Kansas system is covered by the same water operator certification described here, not a second credential.

Water distribution

SS: Small System , Same combined water operator credential as treatment: 12.5 points, 6 months experience minimum.
I: Class I , 13 points, 1 year minimum.
II: Class II , 14 points, 1 year minimum.
III: Class III , 16 points, 2 years minimum.
IV: Class IV , 18 points, 2 years minimum.

Exam fee: $25 examination fee, same schedule as the combined water operator track
Continuing education: Small System: 5 hours every two years. Class I through IV: 10 hours every two years, same as treatment.
Renewal cycle: 2 years

Kansas does not issue a distribution-only certificate distinct from the water operator credential above: this row exists so the site's discipline structure stays honest about coverage, but it points to the same Small System through Class IV water operator certification, not a second exam or fee schedule.

Wastewater treatment

SS: Small System , 12.5 points required, minimum 6 months of qualifying experience.
I: Class I , 13 points required, minimum 1 year of qualifying experience.
II: Class II , 14 points required, minimum 1 year of qualifying experience.
III: Class III , 16 points required, minimum 2 years of qualifying experience.
IV: Class IV , 18 points required, minimum 2 years of qualifying experience.

Exam: State-administered exam through KDHE, parallel Small System through Class IV structure to water
Experience minimum: Same point-and-experience structure as water: Small System 6 months plus 12.5 points, Class I 1 year plus 13 points, Class II 1 year plus 14 points, Class III 2 years plus 16 points, Class IV 2 years plus 18 points.
Application / certification fee: $20 renewal fee every two years
Exam fee: $25 examination fee
Continuing education: Small System: 5 hours every two years. Class I through IV: 10 hours every two years.
Renewal cycle: 2 years

Kansas certifies wastewater operators on the same Small System through Class IV points ladder as water, administered by the same KDHE office.

Wastewater collection

Kansas does not license this discipline as a distinct state credential.

Kansas runs both water and wastewater operator certification through one KDHE office, and the qualifying system is genuinely different from most neighboring states: instead of a flat years-of-experience ladder, Kansas uses a points system that blends experience, education, and completed training into a single number, with a minimum experience floor underneath it.

How the points system works

Every class sets both a minimum point total and a minimum experience floor, and an applicant has to clear both.

Class	Points required	Minimum experience
Small System	12.5	6 months
Class I	13	1 year
Class II	14	1 year
Class III	16	2 years
Class IV	18	2 years

Points come from a mix of documented operating experience, education, and completed approved training; KDHE’s “Operator Certification Education, Training, and Experience Requirements” brochure has the exact conversion table. To even apply, a candidate needs a high school diploma or GED and must own or be employed by the water supply system or wastewater facility they are testing to operate.

One office, two parallel tracks

KDHE runs water and wastewater as two parallel Small System through Class IV tracks with the same point structure, the same $25 exam fee, and the same $20 renewal fee. What is notably absent from KDHE’s public certification materials is a distribution-only credential separate from the water operator track, or a collection-only credential separate from the wastewater operator track: Kansas’s smaller systems typically have operators handling both treatment and distribution (or treatment and collection) under one certificate, and the public FAQ and document library do not describe splitting them into their own classes the way larger states with big urban distribution networks do.

Exam and fees

The examination fee is $25, submitted with the application. Because testing sites cap attendance at roughly 200 applicants, KDHE recommends filing at least 3 to 4 weeks before the deadline, with a hard 2-week minimum. Training is not mandatory before testing, though KDHE recommends it and points to University of California-Sacramento manuals plus its own Kansas-specific Small System Drinking Water and Wastewater manuals.

Renewal and continuing education

Certificates renew every two years from the date of issuance for a $20 renewal fee. KDHE mails a renewal notice at least 45 days before expiration. Training hour requirements scale with class:

Small System operators: 5 hours of approved training every two years.
Class I through IV operators: 10 hours every two years.

Training that applies to both water and wastewater work (pump maintenance is KDHE’s own example) is split between the two credits unless the operator asks otherwise. A lapsed certificate can be reinstated within two years by completing the missed hours and paying a reinstatement fee; after that window it is gone and the applicant starts over. Operators track their renewal status and training hours through KDHE’s CertTracker system or the public Operator Search tool.

Where to go from here

Use the operator-math trainer to build the flow and dosing math that Kansas Class III and IV candidates need, and the process calculator for the same formulas day to day.
