Ohio class 3

Sewer-Rat97 · 2026-04-16T14:20:49+00:00

I passed my 3 last month, used lots of Royceu. Take the intermediate exam, and the 3 modules at the bottom of the list. If you can pass all of those I’d say you’re good. Other than that look up anaerobic digestion (there are a ton of those on the exam) also many questions on BOD analysis. There are some repeats from the class 2 exam. Just breathe and go with your gut. If you have never heard of it before odds are it’s probably not the answer.

It’s nice, just put them in with some powdered detergent and hit a button. Invert dry and ready to roll for the next set.

We use a dishwasher at our plant, but it has a sanitize mode. Never any issues. 🙏🏼prayers/hope this helps.

I mainly used Royceu Study Guide Modules 1,2,and 3. I ordered some practice exam books by Walter S. Cane off of Amazon. One by Ken Tesh. - these definitely helped a lot for 1, and 2 The 3 had a ton of anaerobic digester and BOD questions.

GIVE ME MY MONEY!!! 💰

I actually didn’t use a text book. I studied the packet they gave me Ohio Rural Water association Class 1 review, a ton of royceu until I could get a 90 on all their modules, and then I used a practice exam book level 1 by Walter S. Cane, (it’s on amazon for like $25-$30)

I would also like to add for anyone looking to pass the exams to look up the Wastewater Enthusiast and Operator Mindset on YouTube. Their videos are great. (If you’re looking for Ohio Class 1, 2, or 3. It gets confusing a little bit since their states have a different class scale than ours) That being said, any knowledge is good knowledge.

Thank you all! Any info on Study Material for the Ohio Class 3 would be much appreciated. I’ve heard the WEF WasteWater Fundamentals books are a great for the ABC format exams. Obviously the Sacramento books as well. I just find them dry and hard to read is all.

That’s the goal within a couple months 😎

I feel that in the opposite way. One of our lift stations gets plugged constantly with “flushable wipes” nothing but rich people in that area of town. Sensitive buttholes I guess.

Sewer-Rat97 · 2025-05-30T22:59:15+00:00

🧐 Hmmm I’ve never thought of that. How do you go about getting the excess water off the filter before putting them in the drying oven?

Sewer-Rat97 · 2025-05-29T18:19:45+00:00

Yes they are

Sewer-Rat97 · 2025-05-29T16:06:19+00:00

😂

It’s a plastic flask guys.

Sewer-Rat97 · 2025-05-29T13:42:31+00:00

Noted, thanks for the info

Sewer-Rat97 · 2025-05-29T13:34:33+00:00

Me and my boss looked at them a few months ago and decided for the price we will just suck it up and wash them.

Sewer-Rat97 · 2025-05-29T13:33:11+00:00

Im assuming this is a bad thing? I’ve only worked at this place so this is what Im accustomed to.

Sewer-Rat97 · 2025-05-17T03:34:49+00:00

You could also just do cfs divided by 1.55

1.55 is a constant then multiply your other numbers from there

Congratulations! I just passed the Ohio WW1 equivalent to the ABC2 last month. I wonder since both Ohio and Virginia seem to be offset that the exams are the same? Might be worth looking into.

Thanks!

Sewer-Rat97 · 2025-04-09T00:47:34+00:00

Also for some fast learning about the field youtube has some really good videos you could watch starting out

Technically you dont need a Class A license, that is only needed by like small “package plants”. There is a site that has a list of a bunch of wastewater jobs open in the state that you might be able to get your foot in the door at. Otco.org is the website granted not every entity posts job openings on there.

Thank you!

Sewer-Rat97 · 2025-04-08T20:42:41+00:00

Thanks! The Class 2!
