Nebraska Water & Wastewater Operator Practice Tests

Nebraska splits the two programs between two agencies. Drinking water operator licensure is DHHS, Division of Public Health, under Title 179 NAC 10; wastewater is the Department of Water, Energy and Environment, which was renamed from NDEE and now sits at dwee.nebraska.gov. The first thing to get straight is that Nebraska counts downward. Public water systems are classified Class I for the largest through Class IV for the smallest, based on population served and the treatment provided, with transient systems as Class V. Operator licenses run Grade I through Grade V on the same downward scale, and the operator in responsible charge must hold a license equal to or greater than the classification of the system. Do not be misled by Grade VI: it is not the top of the ladder but a separate credential for Authorized Backflow Preventer Testing and Repair Technicians. The second thing to plan around is that the examinations are sequential from Grade III upward, so Grade III must be passed before Grade II and Grade II before Grade I. Grades IV and V are standalone entry points. Grades I to IV need the exam plus a high school diploma or equivalent plus experience, while Grade V needs only the Grade V exam. The experience table trades education against years: at Grade IV a diploma plus six months as a water operator will do, or an approved basic training or correspondence course, whereas Grade I on a diploma alone takes six years in responsible charge of a Class II or III system, or eight years operating under a Grade I holder. Two years of college cuts Grade III to three years of experience, and a B.S. with sanitary science coursework cuts Grade I to three years. Exams are normally the first Monday of every month at Lincoln, Blair, Norfolk, Grand Island, Chadron and North Platte, and preregistration is required. Fees are $115 for the initial license and for renewal, $50 for an individual examination, and $35 plus the $115 renewal to reinstate an expired or inactive license. The renewal cycle is unusual and worth a diary note: every water operator license in Nebraska expires on 31 December of an odd-numbered year, on a shared schedule rather than on your own anniversary. If your initial license was issued in an even-numbered year you need 5 hours of continuing education at your first renewal; if it was issued in an odd-numbered year continuing education is waived that first time; everyone else needs 10 hours.

No. These are independent practice tests designed to mirror the technical material and difficulty of the Nebraska certification exam. The official exam is administered by Nebraska DHHS, Division of Public Health: water operator licensure (Title 179 NAC 10), and DWEE (Nebraska Department of Water, Energy and Environment, formerly NDEE) for wastewater (or its testing vendor) and the exact questions are not public.

Yes. Every practice test on this site is 100% free, and always will be. To keep it that way, the site may feature sponsors or offer optional paid resources like study courses, but the practice tests themselves stay free.
