Water & Wastewater Operator Certification in Indiana

Your path to certified in Indiana

1. One agency runs both sides, from two desks. IDEM's Office of Water Quality certifies drinking water operators under rule 327 IAC 8-12 and wastewater operators under 327 IAC 5-23. Same office, two separate programs and rules.
2. Exams run through Ivy Tech, most business days. IDEM writes the exams; Ivy Tech Community College proctors them at about two dozen sites statewide by computer. Apply to IDEM, get approved, then schedule with Ivy Tech.
3. Know the two fees. $30 to IDEM per grade you apply for, plus a $45 Ivy Tech site fee per exam. The $45 is waived for November exams at the Indiana Government Center North in Indianapolis.
4. You can test before you qualify. Pass first and you advance toward the grade once your experience is in; fail an exam three times and you owe an approved prep course before the next try.
5. Renew on the July clock. Both certificates run three years and renew by July 1, with the online window open May 1 to June 30 at MyLicense, $30 each.

The exams are Indiana's own, but the arithmetic on them is the universal kind. Drill it free in the practice tool before you book a seat.

Who runs certification here

Both programs live in IDEM's Office of Water Quality, but under separate rules: drinking water under 327 IAC 8-12, wastewater under 327 IAC 5-23 (the wastewater rule was relocated and refreshed, so older citations are stale). There is no separate wastewater board and no delegation to an outside association. One wrinkle worth knowing: the Professional Licensing Agency mails the physical wastewater cards, but IDEM is the certifying authority. The quarterly newsletters and program pages are where requirements are spelled out.

The grades and what they cover

Drinking water splits into distribution and treatment. Distribution runs Grade DSS (small systems), DSM (medium), and DSL (large) by population and pumps. Treatment runs WT1 through WT6 by source and process: WT1 is a small groundwater system with ion exchange or inline filtration, WT4 and WT5 are surface water plants, and WT6 is held for emerging treatment technology. Pass an exam ahead of the experience and you carry Operator-in-Training status until the hours are in.

Wastewater runs ten exams across two facility tracks. The entry rungs are the 50-question A-SO (sanitary) and I-SP (industrial); above them sit Classes A through D for sanitary plants and Classes I through IV for industrial plants, plus an Apprentice pathway. Plant size and process set the class.

The exam: logistics, not cramming

IDEM develops the exams; Ivy Tech administers them by computer at roughly 24 sites, most business days. The flow is the same on both sides: apply to IDEM with the $30 fee, get an approval letter, then schedule and pay the $45 Ivy Tech site fee. Drinking water and wastewater exams alike are multiple choice, 70 to pass, up to three hours. Fail three times and you must complete an approved prep course (for wastewater, at least 8 hours of technical content) before testing again.

Curious what those questions actually cover? The what's on the exam guide walks the blueprint grade by grade.

Keeping it current (renewal)

Both certificates run a three-year cycle with a July 1 deadline, and the online renewal window opens May 1 through June 30 at MyLicense; the fee is $30. Drinking water continuing education scales with grade, from 10 hours (DSS, WT1) up to 30 (WT4 through WT6), and at least 70 percent of the hours must be technical. Wastewater runs 8 hours for the A-SO and I-SP entry certificates, 15 for Classes A, B, I, and II, and 30 for Classes C, D, III, and IV, with the same 70-percent-technical floor. New drinking water operators get a one-year grace period to finish the education requirement.

Training and continuing education

IDEM publishes its approved-provider list and the credit value of each course. Indiana Section AWWA runs operator schools and a boot camp on the water side. The Alliance of Indiana Rural Water is the small-system workhorse, training thousands of professionals a year with certification prep and continuing education. Remember the renewal rule: hours must be the right kind (at least 70 percent technical) and tied to your certificate's field.

Reciprocity

Indiana handles reciprocity by application, case by case, on both sides. Note on your application that you hold an out-of-state certificate, give the number and grade, and attach a copy; IDEM evaluates equivalency. There is no blanket arrangement, and IDEM states plainly that it does not reciprocate with every state, so confirm before you count on it.

Where to get help (small systems)

• Alliance of Indiana Rural Water, inh2o.org: certification prep, continuing education, technical assistance, and an apprenticeship.
• Indiana Section AWWA, inawwa.org: operator schools and the boot camp for water-side training.
• IDEM's program pages carry the application instructions, fact sheets, and fee details for both sides.
• Operator verification runs through IDEM; there is no separate public lookup tool.

Running a system in Indiana

The oversight and funding map for managers and boards.

Rate regulation. The Indiana Utility Regulatory Commission regulates investor-owned water and sewer utilities and government-owned water utilities, but not municipally owned wastewater utilities. Municipal, not-for-profit, and cooperative systems can also vote to opt out of IURC rate regulation entirely; small utilities get a simplified process.

Funding. The Indiana Finance Authority administers both revolving funds from one SRF office, lending to cities, towns, counties, regional districts, and eligible private and not-for-profit systems, with IDEM setting project priorities.

Mutual aid. Indiana participates in the national WARN framework for utilities helping utilities in an emergency. Sign the agreement before the flood, not during it.
