This is the Colorado class D Wastewater sorry for not mentioning that in the title!

I’m so excited. I was so bummed when I didn’t pass it the first time but now that I really knew what to study I realized I walked into that way more unprepared than I thought I was (hindsight 20/20 and all that).

But I’m happy to say that today I retook it and passed!!

I really appreciate all the advice you guys gave me here!

I recently purchased a company that specializes in sanitary sewer flushing, septic tank cleaning etc.
I’m in need of a catchy slogan. Previously it was “Your problem is our problem”. Looking for something more unique. What have you guys seen out there?

Hey everyone,

I passed my California D2 exam a while back, and my certification expires next October. I'm not working in the water industry yet, so I don't have an employer that provides training or CEUs. What's the easiest way to get the required 16 contact hours? Are there any online courses, webinars, or other options that are affordable (or even free)? What would be the simplest way to knock them out before my renewal is due. what did you guys used and what you'd recommend

I’m taking my C test for physical/chemical wwt in the state of South Carolina and need help with study guides. Anything helps

Passed my d3 in ca today ama

I see in the rules youre not supposed to post ads or services, but I made a free education tool that I was hoping I could get some feedback on. The site is wwtoolkit.org

Edit: I just realized I mispelled Wastewater ...

Hey guys, new to the subreddit. I'm a process monitor and I've only been in the industry for a couple of years. Luckily I test very well, but some of my coworkers have struggled to pass their exams. I've found that the study materials for Wastewater, while extensive, are often scattered across the web, or you have to pay some insane amount of money for good training tools, so I decided to build my own (with the help of AI).

wwtoolkit.org is a FREE education and training platform that I'm currently building on my own, but I need eyes on it to ensure things are working properly. I've been working on this site for a bit, and I'm feeling confident enough to actually share it with people now. It's not perfect, but I'm working on it every day. I'll never ask for money, all I ask for is feedback.

I designed the virtual plant with actual wastewater math formulas to try and make it as accurate as possible. It's not 1to1, but It's a good representation so far. The virtual plant also comes with process control scenarios to solve by altering various sliders in each of the sectors of the plant. The site also has practice tests and exams. The practice tests let you choose which subject you want to test on, but you can choose multiple if you desire. So if you're confident in Lab, Aeration, and Math, but are struggling with Pumps and Solids, you can choose JUST those subjects. You can also chose to take a 100 question exam across all subjects with 3 difficulty options.

The site is also equipped with several conversion tools and calculators like a flow converter, or channel flow. I know some things may be wonky, or out of place, but I'm working every day to make this better. The virtual plant has been growing in complexity with each passing day. I appreciate any and all feedback and hope that this helps people!

Hi everyone, have a question regarding certification in California. I've taken and passed the wastewater grade 2 exam, I have an OIT position and am coming up on completing my 1800 hours.

Am I able to apply to get the grade 1 certification without having taken the test? If so, would completing the 1800 hours of OIT be enough or do I need to do a full year of work to apply to be certified as a Grade 1 operator?

Thank you to anyone who is able to help answering my questions, I really appreciate it.

Hello!
Recently my job has tasked me to find Mono-incinerated sewage sludge ash (for an upcycling project), and I'm having a difficult time procuring the product. Is there any advice anyone can give me, or links/contacts that will help me? Thank you!!!

Im taking my waste water treatment 2 test tomorrow. Any last minute study advice for me?

What you you say are must need tools for a WWT Operator? Other than those required for lab.

First time becoming a wastewater supervisor I have my top license in the state of South Carolina and have been in wastewater field for 12 years both industrial and municipal. Any tips?

Never forget the joy around us and remember to stop and take it in sometimes :)

I'm getting ready to take the T3 by doing the AWC T3 exam prep course. It does seem pretty thorough, but are there any other resources you used that you found helpful? Anything on the exam that maybe wasn't covered by AWC or that caught you by surprise?

Thanks!

I’m pumped to take class Monday and this week. I’ll be taking the exam in December. I’ve visited two facilities to talk to folks. They gave me tours and it’s fascinating. I’ve applied for a thermal biosolids dryer position. Hopefully I can get something going. Just wanted to share.

I’ve been in collections for 3 years but the city I was working for didn’t require any CWEA certifications. I recently got a job at a wastewater district that requires at least a grade 1. With my experience in the field should I try for the grade 2 exam or just start with the grade 1 and work my way towards the 2. What type of questions should I expect to see on these exams and what material should I be studying?

Currently a plumbing apprentice but want to switch over to waste water operations would I have a better shot at over other candidates, all you need to do it write a exam here in Ontario for it , also how’s the hours , is there lots of ot , and does anyone from Ontario Canada work for ocwa or municipality

I currently hold my level 3 in NJ and am currently studying for my level 4 wastewater licence. I've heard some people say the 3 is the hardest test and just wanted to check on here to see if people agree. Most of the 4s I know got their licences decades ago and I assume things might be different now. Still gonna study like it will be the hardest test of my career either way lol.

I have a virtual interview coming up for a plant operator position with no experience. Who i talked to on the phone before i applied said something along the lines of this is a mostly solids position, focusing mostly on the solids/biosolids. Could someone in this area tell me what all this entails and what to expect?

Do you have ideas for making this [r/Wastewater](r/Wastewater) even better than it already is? Do you have

- 15-30 min per day, ( longer, one-off projects may be available, which may involve coding and/or constructing automations )
- willingness to go by the established sub rules and platform rules
- willingness to contribute to rule reform
- open mind and
- critical problem solving.

Edit: The Reddit-automated mod team application form is not acting right, so if you’re interested, message the mods and we will direct you to a form outside the platform.

Hi everyone! I’d like to know if anyone has information about talks, workshops, or even postgraduate courses focused on dairy farm wastewater treatment lagoons, or wastewater treatment systems for dairy farms in general.

I’m from Argentina, and there isn’t much available here on this topic. I’d really like to deepen my knowledge and learn more about it, so I’m looking for any courses, talks, workshops, or other accessible resources that could help me get a better understanding of the subject.

Any recommendations would be greatly appreciated!

P.S. A few photos from my field sampling work.

Friendly reminder to get the integrity of you welds checked on your tanks. not just visual inspection. Neighboring system to me. 300,000 tank ripped like a soda can at the bottom. Total loss

I added two pictures the old busted one is the one I need repaired and the other picture is the new one I found online but even that company doesn't seem to have repair kits on their website I did put in a request for them to contact me about it.

In the past I have tried to use a piece of bicycle chain and that did not fit at all so I'm trying to find a place that I can order repair parts.

If y'all have any ideas I would greatly appreciate it. Thank you for your time.

I do not think I am using the right flair, but I am not sure how to tag this (sorry)

I am working on strengthening our response to hazardous atmospheres. For context we use MSA ALTAIR 4XR and 5X gas monitors.

Our alarms respond as follows:

• Low alarm: 10ppm, which is the 10-minute ceiling window (NIOSH).
  • My understanding: When the low alarm goes off, we have 10 minutes to be in the area and then we must exit.
• High Alarm & STEL: 15ppm
  • OSHA's instantaneous ceiling limit is 20ppm.
  • My understanding: We must exit the area when the high alarm goes off.
• TWA: 10ppm
  • My understanding: The total amount of H2S our crews can be exposed to in a 8hr day. So if the meter reads 10ppm every hour for 8 hours, that would average 10ppm for the entire day. But that does not mean they can be in a room with >10ppm H2S for an entire 8 hr day.

So, even if the TWA for a work day does not hit 10ppm, it is still not permissible to be in a process room or confined space with H2S exposure over 10ppm for longer than 10 minutes at a time, especially at or over 20ppm. In our health and safety program it also states that a respirator will be worn if we need to be in an area with H2S between 10 - 90ppm. However, the program does not state a time frame for how long we can be in those areas with a respirator that have high H2S readings

Can someone please confirm that my rationale is correct? A guy on our crew swears up and down that the TWA ultimately determines our H2S exposure and since they are not in areas with high H2S all the time (maybe 4 hrs a night), they can be in places with H2S over 15ppm as long as they don't hit the TWA limit.

However, I feel pretty strongly that if we are getting alarms over 10ppm and 15ppm, we need to respond to them according to the occupational exposure limits and our health & safety program. So obviously, we *should* be following the program, but the TWA is confusing people and now myself.

How does your plant handle atmospheric monitoring and enforcing responses to H2S? Do you wear respirators when H2S is high?
