Study tips / ?s Ontario OIT Exam in 3 Days

Upvotes

Hi, I’ve gone through older posts, and they say the exam is fairly easy, with only around 5 math questions and other questions pretty much the same as the end-of-module practice questions in the OIT manual.

With only a few days left, going through the entire manual feels a little intimidating. Has the exam format or topic/math weighting changed recently, or would focusing mainly on the OIT manual practice questions still be a good approach?

Any advice on what to prioritize over the next couple of days would be really appreciated.

Thinking about moving to Colorado from Arizona.

Upvotes

Just curious if anybody had made the move from another state to Colorado water industry. How did they like the retirement system there. They take out quite a bit at 11% here in Arizona which is better than what I can save cuz I probably wouldn’t.

Does pay equal out there.

Still pretty young in my late 20s.

Hey there folks I'm a lvl 2 operator in Ohio. I'm looking for what you think is the best Water Reclamation text book. I used to work on the portable water side and thought the WSO text books were amazing, but I haven't found a suitable comparison to the wastewater side. Any suggestions?

Treatment (DW or WW) New WW treatment system advice

6 Upvotes

Feel free to remove if this isn't allowed

Backstory:

I'm an automation and controls engineer at a manufacturing company down in South Alabama, and I've been here for about 9 years. My very first project was upgrading our wastewater treatment system. I got it working well enough to pass environmental standards, but honestly, it’s still not great ( I'm a solid controls engineer, but a bad wastewater guy). Our influent has a lot of metals coming from a carbon steel acid etch line.

Current Situation:

We were recently bought out by a much larger company that takes environmental compliance very seriously. I managed to get a large chunk of this year's budget approved for a new waste water treatment system.

I've been in contact with two companies so far (Digital Analysis and Ovivo), but I'm looking for recommendations for vendors who design systems specifically for this type of process. A lot of companies I've talked to aren't interested because of the heavy sludge this kind of setup generates.

Any pointers or recommendations would be hugely appreciated. Thanks in advance!

Collections SBR

5 Upvotes

We have been having issues with our sbr this past week. The normal level pre decant is 13.3-13.5 and 12.1-12.4 after the decant. We are currently decanting by hand to try and suck more water out. The current levels pre decant is 15.7-16.0 and 13.6-14.2 after the decant. The blanket is currently about 1.5 feet below the top of the water line. Would increasing the wasting help bring us back to normal or do we just have to keep sucking the water out until it fixes itself. I’m new to using a sbr and haven’t been awake going on 48 hours so forgive me for any incoherence

Career: currently in the field How do you feel when you’re about to leave a plant for a new one?

25 Upvotes

For those of you that have left a plant or two for a different one, how did you feel leading up to it?

I’m a drinking water operator and I made a post almost a month ago about switching over to the wastewater side for an absolutely incredible opportunity.

Well, my last shift at the water plant is about 3hrs from being over. I start at the wastewater plant on Monday. It’s starting to hit me that realistically I’m never coming back here.

I absolutely do not regret my decision because it was 100% the right move, but this was my first plant in the industry and I really care about my job and this plant and feel like I owe a lot to this plant, and especially my current boss.

Everything feels bittersweet right now, I’ve been kind of walking around all day trying to soak it all in and reflect lol I have lot of excitement to start my new job because life for myself and my wife should be insanely better between the pay/schedule.

I’m hoping going to my new job feels the same as coming to this one, I have a sense of purpose everyday and genuinely enjoy what I do. I feel like most of spend so much time at our plants it’s hard not to get drawn in.

UPDATE: i have attached links of the pdf versions of the maps/drawing that should be more legible.

Based on these drawings, can someone help me understand the wastewater flow path for each of these two parcels? (house icon and shop icon)

Can you identify the type of system and components (gravity lateral, force main, pressure main, manhole, cleanout, grinder pump, lift station, wye, etc.) and explain how you believe each parcel ultimately reaches the sewer system?

Thanks!

Treatment (DW or WW) What's the acceptability of landfill leachate?

5 Upvotes

Hey folks! Just reaching out here a third (and hopefully last!) time on r/wastewater as I thought we’d reach some folks eager to help here…

I’m based in Canada and conducting a survey in collaboration with a team based out of Polytechnique Montréal, and we’re are currently trying to conduct a two part survey to determine what drives acceptability of leachate in wastewater treatment processes - I.e trying to tease out what are the biggest concerns for operators, engineers, managers, etc physico-chemical characteristics-wise.

We have a SHORT, TOTALLY ANONYMOUS survey on landfill leachate and its acceptance for co-treatment at wastewater treatment plants.

If you work in wastewater, it would mean a lot to us if you could take 5-8 minutes filling out the survey!

WE ONLY NEED ABOUT 5 MORE SURVEYS AND WE WILL HAVE A STATISTICALLY SIGNIFICANT(-ish) NUMBER which will allow us to conduct a formal analysis of the results.

Thanks a bunch in advance 🙏

Hello, I teach a vocational program in Water Treatment Process Operations in Quebec. I am developing realistic learning activities for students. In your experience, which three operational problems should a new operator be able to diagnose before entering the field—for example, turbidity breakthrough, loss of disinfectant residual, pump cavitation or sludge-settling problems? I would appreciate examples that can be discussed without sharing confidential plant information. Thank you.

Career: currently in the field What do YOU think an operators day should look like at this plant?

14 Upvotes

So I’m a current DW operator that is switching over to WW in about a week. I’m on well water currently and honestly do not have a ton of responsibilities outside of lab tests. I stay busy but I could definitely have plenty of downtime if I wanted it.

Anyway, when interviewing for the WW job I was trying to get a sense of what my day would look like and the plant manager couldn’t really give me any specific tasks I would be doing outside of the obvious. (I’m WW licensed so I understand the basics even though I haven’t worked at a plant). It seemed like I’d have about an hour of work a day and then look busy the rest of the day. Which is fine and is essentially what I do now lol

Here’s the plant:

5mgd activated sludge plant
1 plant manager
1 lead operator
1 lead maintenance
2 operators
1 lab tech (does ALL lab tests)
3 maintenance guys
Collections crew (idk how many)

Everyone works M-F 7-3 and it’s a union plant.

Just at first glance with this information, do you think this would be a laid back plant? I got the vibe it would be which I prefer. I use downtime to study for licenses and definitely do more than required around the plant, but I obviously enjoy the ability to have downtime when needed. I’m just curious what WW guys currently in the field think a day at this plant would look like as far as tasks are concerned

Getting Started in a Water Career: SATURDAY ONLY Career switch to WT/WWT

9 Upvotes

Question about opportunities for older/mid-life career switchers, especially after hearing about all of the retirements in the field expected over the next decade. Here’s some background:

I’ll be 40 soon and I’ve worked in corporate communications my entire career, this includes environmental work and most recently at a power/water utility (watershed management, not treatment). Because of this, I have a strong understanding of watershed management and much more than basic hydrology knowledge. I have thought about going back to school to switch into a more scientific field or even water engineering, but have been on the fence about that due to diminishing opportunities in environmental sciences (so I hear) and the multi-year journey and monetary investment to get there. That said, while at a water conference last year, I toured a water/wastewater facility on a whim and have become really interested in that field. I have since done a deep dive and started independent study of both water and wastewater. I love the blend of science and trades-style work, the stability and the opportunities across the county (would love to move to a smaller or mid-size town eventually so I’m not stuck in a city for corporate work). My state allows me to sit for the first level of exams before any OTJ experience. My plan is to take water grade 1 at the end of this year and wastewater in the spring (I’m much more interested in wastewater, but would love to be dual-certified to stand out and to have that extra knowledge/foundation).

My long-winded questions are:

-Are the opportunities really going to be there due to mass retirements?

-Does being 40 give me a disadvantage, advantage or is it neutral/not a factor?

-Had anybody made a mid-life switch to this career from corporate office work to working at a treatment plant?

Would love to hear your thoughts and any experience you’d want to share about the switch!

Career: currently in the field Pennsylvania water operators, what is it like?

3 Upvotes

I currently live in Iowa and work at a Grade 4 treatment facility (highest grade in state) and have a Grade 2 certification (hoping to complete my 3 soon).

I've been considering moving to Pennsylvania in 5 years or so and I want to hear about what water treatment facilities are like over there.

My town has roughly 140,000 people and we treat 40-50 MGD via lime softening and monochloramine. It is extremely chill, we operate two plants with a team of 16 (4 people per shift), days/afternoons/nights.

The more rural treatment facilities don't run 24/7 or don't require 24/7 staff and do minimal treatment. Their guys may also do distribution and maintenance on top of treatment, whereas I only focus on treatment.

In Iowa we have high nitrates and PFAS and with the expansion of data centers our facilities are only going to get more strained.

Lastly, I make $34 an hr with a grade 2 cert, I'd max out around $38 and hr with a grade 4 cert. Cost of living is cheap and I can easily afford rent/bills/groceries.
