petition for more of this game so the editor can keep his job.

I'm glad the devs gave you the full game, Matt! You deserve it! Especially after giving them so much free publicity that they thought they were being targeted. :)

"Hope it's not too boring." He says as I sat here and barely finished my meal in the 35 minutes it took to watch. But really, seeing the immense engineering and work that goes into what we take for granted is always a fascinating time. The common person doesn't consider everything that goes into making a drainage network, they just think "Why does it take them half a week to just put pipes in the ground?" It's really cool, and I'd love to see more.

I never thought I'd be so interested in drainage engineering, but here we are. Keep nerding out, Matt!

I can't be the only one who enjoys the more serious RCE videos over the less serious videos

Hydrology Engineer again! Like I said last time, it's great to see a game where Matt can just nerd out and be Matt.

“Like… it’s nonsense.” Lol Matt gets real sassy when he talking about his actual work. I love it. “Personally, I’d use common sense” I’m dying.

Oh my, here we go again. Glory to the editor! Matt, thank you again. I enjoyed this video. I learned quite a bit about some of the thoughts that go on in UK. I'd love if someone could summarize some of the rules you have to consider. ... site note. I just realized that my google dictionary was set to UK. I was confused about some of the spell check squigglies I was getting on commenting. Ok back to it. I wanted to just give a stream of thoughts and comments on this awesome video. I enjoyed watching this as much as you all. 1.2m is new to me. The game has a concept of jurisdictional constraints. Currently all levels are set to my local constraint which is 8ft gutter spread (technically its based on 1/2 road lane width + paved shoulders and gutter) When you start the game there is a tablet screen that explains the rules and penalties. The idea is that we wanted to be able to swap out your ruleset/penalties based on your jurisdiction. This isn't 100%, as you can imagine there are so many jurisdictions. We have found that some engineers might only ever do projects in a single jurisdiction but even local vs state can be different. Residential vs highway can be different. Another one I've been told about is that while locally here we are allowed to daisy-chain catchbasins(gullys) together, even parts of the US like Florida, or in Dublin, Ireland you are not allowed to. All must connect to a main trunk like Matt showed in the video. The idea is so that if one drain clogs it doesn't effect the whole network. Brilliant! We don't have this double gully. If you have the low points turned on your structures will snap to the low point. Locally again this is a requirement that you have a catchbasin at the low point and flanking ones based on water depth. Maybe the double gully could be a single structure. I noticed the if you don't place one at the low point but rather on either side, depending on the distance and the longitudinal slope you might be calculating on grade spread vs sag spread. We have several sized grates as well as 10ft curb boxes but they are not available on this site. Actually I have modeled a bunch of DOT approved headwalls as well but they are not in game yet. A lot of these are ordered from local suppliers due to the weight and cost of shipping. If anyone has favorite local suppliers let me know so I can get their catalog. The streams of water going over the curbs are placed wherever a large amount of water is contributing to the peak flow. We added those because sometimes it was hard to communicate why spread would jump up almost instantly. We do take into account the entire sub-catchment when calculating our flow. We're show the longest flowline for each which can be up to three parts. Red is sheet flow, Yellow is shallow flow and black is channel flow. The rule we've set up is you can have up to 100ft of sheet flow. Once you hit the driveway or drop into the curb it should be channel flow and then everything in between is shallow flow. Our professional tools allow a lot of customization here. I'd be curious to hear what others think on this. Modeling spread at driveways isn't the same as modeling gutterspread. We have several ways we can do it from doing a linear segment between the values on each side to a cubic estimation or doing a V channel calculation. The V channel led to interesting reductions in gutterspread at the driveway but then it would increase again just after. This was due to some driveways being flatter than others and the water naturally filled that area leading into less depth. It might be more accurate but it didn't look right. I want to build a physical model to study this. There was an issue also if the driveway was too flat you'd get a massive pond. Using a linear estimate is used on most and the cubic one is used on some of the cul de sac driveways which help accounts for the curve of the curb line. One last thought... The pipes have a min/max cover rule as well as a clearance rule. This level doesn't have utilities but in the others your pipes must be 12" underground minimum. They also must be 15" below supply water and 15" above sanitary sewer lines. The slope shows as negative which is just how we at Carlson show downhill but I have heard of and seen plans that don't show negative. its -0.10% so 1/10th of 1% which is another local rule. We have a max slope of -10%. All the pipes are imperial spec pipes. The metric measurements were added for metric users that didn't understand our confusing system of units and measures. We will be adding actual metric spec pipes so the sizes won't look weird (unless you switch your settings to imperial). I have found that the metric pipe measurements aren't standardized and actually different per country. So my question for all of you non-US engineers is what is your size gapping in pipes. What is the smallest pipe you have for storm sewer drainage (materials?) and do they go up in 50mm increments? at which point does the size gap change to 100mm or 200mm increments? All of our pipes are modeled with actual thickness, flare length, overlap amounts (in the case of RCP). We only have a single RCP class right now but I spoke with an engineer recently about load values and how deep a pipe must be vs its diameter to hold the load of traffic. Ok my coffee has gotten cold now. Thanks again to Matt (and the editor supreme) for taking their time on this video. Thank you to all of you that have left just amazing comments and feedback on this video and the last one. I along with several of my colleagues have been reading each and every one of them. And thanks to you Carlson customers that have reached out to your local dealer or sales person. I love having them run up to my office and tell me that someone reached out about this passion project game we built. One more last thought... We hear you about the price and the desire to have it on a platform like steam. I can't release this game as is on steam, but thanks to all of these comments and the amazing videos we have started the conversation of what the steam puzzle version of the game looks like. After i reheat my coffee I'll be working on that. Give me your thoughts on what you'd like to see. Any thanks to all of you who have purchased this game. I can't wait to share with you some of these amazing updates we've been working on.

I'd love to see the 2 hour plus unedited video honestly.

And then someone changes the roadway profile a few days before submittal and you have to work all night to redo everything. The life of the drainage engineer.

Of course the last video done well. My uncle (who worked in the same field as you) said that one of his ex colleague who became a teacher referenced your video to his pupils. He (my uncle) said "that RCE guy did a good explanation that even a layman would get" then he got on a tangent about contractors cutting corners and the blame falling at the engineer feet.

No joke, this is actually really addicting to watch. I love how you get really nerdy about the drainage, it's something you never really see in other videos. Hopefully you'll make another one of these as well

We like seeing you do well at things, Matt. Bet the dev didn't expect a training sim to get so much attention from gamers, but let's face it we'll make a game out of anything. There's literally competitions for making spreadsheets.

As entertaining and efficient as your content normally is, this is just really freakin' interesting. Kind of like 'how it's made', a professional explaining things you just hadn't considered giving a real appreciation next time you're driving down a road and notice none of the manhole covers are in the middle.

there's a different style that's done in the US, at least residentially. Here, you're allowed to pipe gullies to gullies. it can make the whole piping puzzle much easier. Also, curbside inlets can handle a surprising amount of water. curbside inlets are like, the ones without the grates. They handle a lot of water by basically being a really wide grate. However, they can be more expensive by being concrete topped instead of a small iron grate. However, they integrate into sidewalks VERY well. I woulda planned the water handling from the bottom (hue hue, lowest elevation) up. See how much you can save by doing gully-to-gully piping

I'm glad you returned to this! In the previous video you were worried that folks would find it boring, but I find it to be quite a fascinating subject. You're clearly very excited to share your previous work and knowledge with everyone, and your explanations are energetic and easy to follow. Thank you, Matt and Editor!

Give us the raw video. I'm here for the engineering! I've put on my glasses and pocket protector, I'm ready to nerd out with Matt!

Maybe it's because i studied engineering too (Telecomunications in my case) and i ended up woirking in coding. This brings me back nice memories of working on assignments in different suimulation programs. The editor might have complained. But i think i would have even enjoyed the 2 hours of raw footage.

Never thought I'd be interested in the finer details of drainage. But here we are

I don’t know why, but when a professional talks about their work with such passion I’m on the hook to watch. Thanks Matt!

Funny enough, here in Brooklyn NY they've begun construction in MULTIPLE areas to install storm drains, so this is perfect timing seeing this in my notifications. I do wanna know how they work.

Since the last video, I started to pay attention to the height of the road and how holes affected the water flow in a rainy day. Thanks xD

The way you talk about all this engineering work, is really what sells this video and the last one. Sure, some of use want random information that doesn't really effect us. But, others, they're here because they enjoy your content and how you do it. Keep on keeping on :)

I appreciate the fast talking industry terms, and dialback explanations. Its like a cheat sheet on how to respect someone else's expertise. Kudos for being so invested in this vid that you forgot to show perfectly normal; totally not unusual: completely appropritate suggestive shapes. The fact that you said this is a "more accurate" simluation immediately made me want to see the "real criminal engineer" version where you (*probably without much technical explanation) show us just how bad things could get if you wanted to flood this neighborhood completely to buy the land cheap. You do amazing videos so I hope they are as fun to make as they are to watch. Keep at it.

Where can we get the uncut version (2hrs+ of this!!) I'm so happy you came back to this! Joining Patreon. This is surprisingly similar to IT engineering. In fact we call Ethernet and fiber and all the cables pipes, carrying bandwidth instead of volume. But we have many types of gulleys and manholes: switches, routers and bridges

My wife is a civil engineer and does this every day. It's been fun to watch these and follow along from what little I've picked up listening to her talk about her job over the years. Love it, keep them coming!

Don’t know if it is specific to UK, but here in Canada, gullies are joining the main pipe with an underground tee, never in manholes. Also, the stormwater pipe is on one side of the road because the sanitary sewer is in the middle and much lower, and water main is on the other side. That way, a leaking sanitary sewer won’t contaminate the storm water system, and the water main won’t freeze because it is far away from the storm water pipes full of the cold ambiant air. And it is always better to go with deeper manholes than longer pipes because of the drag, so it doesnt matter if the main line goes against road gradient, but towards the pond.

God help the Editors. 😂 I love listening to nerds nerding out over niche subjects. I only wish that I could have seen the looks on the Devs face when they found out about these videos. The look of confusion would be delicious.

As a current student engineer it's amazing to see a game that can be enjoyed but is also realistic! I Love how you nerd out and talk about all the behind the scenes that happen 😂, would love to see more indepth engineering games like these!

More of this simulator! I love how you're able to bring your actual experience to this simulator and teach us some concepts from that background. It doesn't have to make us qualified drainage engineers; just informing us enough we can look at drainage designs we see and think, "Oh yeah, that's why that's there! The flow width must have gotten pretty big there!"

Really cool to see Matt in his element. Also puts into perspective how much stuff is under ground. Drainage, sewer, power, internet/TV. I wonder what the guidelines are for all of that being in the ground together.

You know it’s a serious video, when there is no knob jokes in it. To the point my wife even said, “Hey that’s your gaming guy, is he okay? He didn’t make a knob joke.”

I'd love a little series on this. I'd love to see a few roads get approved designs. The subject is fascinating to me. I always adore learning about urban planning and things, even though I don't have a professional reason to.

This and Grady's Practical Engineering channel has taught me a lot about the hidden complexities of civil engineering.

I'm not a drainage engineer, but I do work for a utility boring contractor and and responsible for running the locator when we do a bore. I've had quite a bit of experience doing on-grade sewer installs. I wanted to mention that because I couldn't help but laugh when Matt's designs in the last video wasn't working out and his gulleys and manholes kept getting flooded out. Being in an industry where we do a lot of underground work, I really appreciate this kind of content. It's goofy and silly, but it's also interesting and informative. I've actually discovered things that I hadn't considered before when it comes to drainage...and I'm probably one of the most technical, analytical, and mathematical guys on my crew. Please do make videos containing the next two levels. I would thoroughly enjoy it.

I think the reason the previous video and this one are so popular is because it's absolutely wonderful to hear someone talk so passionately about a topic that they are knowledgeable on. Like you say at the end, most people don't have a clue what's underneath the ground, and it's fascinating to learn the details of something that you otherwise just take for granted.

I'm so dead of the editor's message 😆 personaly I wouldn't mind the 2h video because as a nerd myself I'm interested in all those bits, as long as he isn't repeating himself for like 1h out of the 2 which is actualy quite common when to try to make anything accessible to newbies

I am so glad that you were revisiting this. It was very educational, and I am actually impressed with the knowledge that you're willing to share with us. Just the fact that you're educating us in such a way This is so awesome

I love it when Matt can actually explain and show his profession.

As a Mechanical Engineer, myself, this was nothing short of fascinating. I definitely want to see the other levels!

This video explains some of the planning choices I've met with IRL to no longer be questionable. Thank You.

I'm slightly disturbed how excited I am about this video appearing, but also... knowledge is nice, and getting more information on anything is really appreciated, if that means looking at someone playing a game idea kinda learning tool, then so be it, I'm in ^^

i love seeing someone so passionate, you've found the intersection of your passions and i would love to see you teach your knowledge through play.

One: Leaving a like for the editor's suffering Two: If RCE gets a different editor we riot Three: I think the original video did so well because...well....I for one love watching Matt nerd out about his specialties. Building bridges, civil engineering, and city designing is much more interesting when the person has some amount of real life experience on the topic. It's what got me hooked to this channel in the first place! Anyone else playing these games and I have no interest in it, but Matt actually explains things and has stories about it which makes his videos very engaging for me. Bridge review and thinking about the "boosh bill" is entertaining too! Note for the editor: We see the fruits of your suffering and appreciate you!

Wait. Wait Wait Wait just a minute.... is Matt actually smart? 😮 Honestly this was brilliant, great to hear Matt explain something that most people know nothing about in 'down to Earth' terms. Boosh.

This feels familiar to how RCE used to nerd out explaining real life stuff on Cities skyline and poly bridge. This has nothing to so with me but it really satisfies that information hungry part of my brain. I nowadays watch everything on 1.5x or more speed but the pacing and info dump here kept me engaed enough while at the same time ensuring I wasn't bored by over explanations.

This is actually my job! I’m a union utility pipe layer in Wisconsin. I spend most of my year ripping up roads and putting in water main, storm drains and waste pipes! Someone like me is the reason you can poop, have water, and aren’t swimming to each destination! It is a lot of hard work. It’s heavy construction and not for the weak. I come home covered in mud daily and my body takes a beating, 12 hour days are normal. If there’s any details you guys want to know you can just ask me! (Also yes there is a ton of math that goes into it!)

I'm loving this series! There's something so fun about Matt nerding out and being super passionate about drainage. I'm learning a lot about drainage infrastructure too! Also, props to the editor not just for tackling the raw footage, but also for the new choices of music. I liked the background music in this vid a LOT more than that annoying one with the trilling flute haha. EDIT: Yes! Do more levels!

I'd love to see more of these. I hope the devs add in a random map generator or something.

this is the single most technical and serious game rce has ever played

As an Aerospace Engineer, I was not exposed to other disciplines that much, and it is very interesting learning about the type of projects other engineers do. Keep this up Matt!

Hey there, I’m actually a young Engineer just starting my career. I’ve actually found this video helpful in learning how to do this day to day. Thanks for the great content.

This is genuinely really informative, I'm pleasantly surprised! I love seeing you nerd out over your job Matt hehe

this is the second best series on your channel after timberborners

Dear RCE. I really love this channel. As soon to be (hopefully) engineer I’m interested, even if it’s not my field of study, to your nerding. Please, tell me that you have plane to upload the full 2 hour footage raw (or with little editing is possibile). I want to know more… I NEED IT!

I havent looked at roads the same way since; judging drainage has been on my mind every time I step outside

Dubai just needs to hire you. Small rainfall and half the city roads flood. Drive through foot deep water to work.

I absolutely love this series, please continue it 🙏

It’s a breathe of fresh air to think that watching you Matt, you can learn while enjoying watching gameplay. Most KZfaqrs I watch I’m mindlessly looking not learning or anything. I watch this video I’m now a fully qualified hydro engineer 😂

Thank you for this video, I just started studying drainage design as part of my diploma and this is really informative. It's great to see all the considerations you put in your design, which will be very helpful to my course. Thanks so much!

Haven't watches the video yet but always love it when Matt gets to nerd out. LOL He gets so excited.

Do trees effect where you would put a gully? I would have thought the leaves falling off trees in autumn might make gullies below a tree more susceptible to blockages

It’s because of videos like this that now I know more by a lot, what my brother means what he is studying and doing, which is civil engineering of course. I think when you are started want to do something else with your life, you should really consider being a lecturer. Lol imagine sitting in class with Matt as the lecturer. Definitely gonna attend every lecture, with the fact he can nerding this thing for 2 hours definitely a starter. Seriously best random channel recommendation youtube has offer me. 😂😂

This is hands down so interesting to watch. It's rare you have the opportunity to watch someone knowledgable explain the details of their job with the aid of simulation software which makes every explanation so graphical.

I'd love to see You do all of the levels !

28:00 even the editors missed that it is actually indicated...

Like I said the last time: No matter if I'd find it boring to actually play this game, what I love in this channel is when Matt is in his element, talking about things he understands and getting me to get them, too. And well, this game is just that, distilled. I could probably watch a lot of it.

As someone who is just starting to learn the very start of the basics of drainage in the construction industry this was very interesting and informative. Great video

Surely the type of soil has an impact? Maybe it's not modeled in game properly. Would be interested in a winter version with snow melt.

Because watching people play video games that pertain to their job is something that I didn't know that I needed. Now I want to watch a farmer play farm simulator

So educational! I did study a bit of civil engineering while I was studying drafting. I ended up with a job that uses both mechanical and architectural drafting. Walls can be more complicated than you think

I'm an EMS student and I have no knowledge about drainage engineering, but man it is interesting seeing you do it and explain everything. Hopefully you do more videos about this.

The editors need a raise for this one

YES! Another drainage video! Now we must wait for the next because its really interesting!

I really found both these videos fascinating, always glad to see competent people on KZfaq sharing their nerdiness!

This makes my brain happy, solid information, math, and the instant gratification when the build works, I need this software lol

Love this! Make more of this! Edit: Thank you for the like.

Day 5 of notifying people that the Discord suggestions forum is a better place to suggest games to Matt. (Just don't ping him!)

Yes! I love the first one. It's a little bit ASMR. Really scratches an itch of wanting to have something explained by an expert. Release the 2 hour cut!

Can... we get a lot more of this? Like, your channel is entertaining but I enjoy the educational aspect of the fun.

Release the 2 hour RCE cut!

My local council, one gully will do, who cares if half the road is underwater most storms.

That was surprisingly educational. And it's really enjoyable watching people genuinely having a great time and sharing their experience. Thanks to the dev for supporting and that's to Matt for the unfiltered nerd barrage. Also, give you editors a treat for these. They deserve it as much as you did.

The last time I was in Japan, the area I was staying in had gutters that were actually narrow channels recessed about a foot below the road surface. They were mostly open, but whenever there was a driveway or front walk, there would be a grating. So in a sense, every house had its own very wide, very short bridge. I think you'd approve. (It did mean you had to be careful walking home at night--side streets generally don't have sidewalks there--because I'm sure if you accidentally stepped in it you could turn your ankle pretty badly)

Great vid!

0:21 just for making me laugh mr editor I'll like subscribe AND hit the bell.

Having found your channel from when you were doing INFRA, it feels appropriate going from "how not to do civil engineering" to "how to do it right", at least for drainage. This was really neat!

Something satisfying about watching a professional do something really well. Good on you matt

we viewers really like u matt, so its cool to see u nerd about stuuf u like it, cz it makes us like it too. At first, it maybe not look like it does, but the way u talk about stuff and create content, makes us feel like we are apart of this channel, and content like this is what makes things worth it.. we love u matt. Love from brazil

Matt, i'm an old subscriber and this video makes me happy. I still remember how u explained tension on the bridges, u told about how dangerous it can get when steel beam in the wall appear in infra, and how well u explain technicality of fixing road in the road maintenance game that u played ages ago. So this one really makes me happy u can explaining us how drainage works. Matt, i still remember that u once having a collab with another polybridge youtuber and you talk about the past. U said u once wants to be an architect but cannot be it. So u go being a civil engineer. That info is pretty unnecessary for me but that's far i enjoy watching ur videos. Hope u can be healthy always.

im having flashbacks to when I would watch people going out and unclogging random drains, its interesting to learn the more intricate details of them

Hi there. I’m an actual architect in US. And I just wanted to say you’re the first civil engineer to explain how topo works without needing to sit in a 3 hour zoom meeting. Engineer majors need public speaking courses.

give the editor a raise, and give us a part 3?

It's interesting because it's fun to listen to people nerd out about their special interests😊

I freakin love these videos. As an engineer who understands looking at spreadsheets, I’d LOVE a simulation game like this for my specialty!! Understand why RCE geeks out so much over this game

These engineering focused episodes are the videos that interest me most, thanks matt :)

Mat would be a great teacher, really patient explaining all of the technicalities

I don't even know how you found this game in the first place, but I'm glad you did

0:21 For you mister Editor, all the likes. If KZfaq were still using the the star rating system you would get all 5 stars, and a hundred alpacas. XD Cheers guys. I love Matt's videos and the great humor his editors bring to them. Not taking one self so seriously while making a serious, dedicated, well put together and beloved job like you guys do is part of the charm and appeal that makes us come back and enjoy these videos. Keep up the great work guys.

Is this engaging game play on its own? Not really.... Is Matt absolutely getting to show us what he loves? Absolutely! This bridge of a video is 10 out of 10, would watch more.
