3:41 My friend was an engineer that helped with the Flood Control Tunnel project. He said it took a long time to get the project approved. Interestingly, soon after completing the tunnel there was a massive flood level rain storm that came through San Antonio in 1998. He drove through downtown San Antonio just after the storm and saw a few people walking around and others eating at restaurants. Those people had no idea that the Flood Control Tunnel saved the whole downtown area from being under 20 feet of water. The tunnel prevented millions of dollars in flood damages and paid for itself with that one event.

[@intractablemaskvpmGy]

I remember that day- it rained 18 inches and messed a lot of stuff up, but that tunnel was a godsend for downtown

I enjoy the "deep" dives you do on engineering projects, offering some of the more in-depth details of projects we might not otherwise have heard about. But there is something quite charming about this quick look video of you showing off your cities features in person. I like it. I'd be interested to see some more "Tom Scott-like" videos in future where you visit a site near you and give an explanation of its importance and how it works for a few minutes

there used to be two water towers in my town when growing up. they ended up getting disassembled over the years because they needed repairs and werent needed in the water system anymore due to their excessive height and small capacity. it does make me feel somewhat melancholic when i think about how theyre now gone. it used to bring me some pride to see my town name plastered across that big blue tower in the distance

Ditto on the how things work books. As a little kid my favorite books were by Richard Scarry. Anyone remember those? They were animated books with very detailed illustrations of how things work. For example they would show pipes in the walls of houses, even colored hot and cold pipes accordingly and I’m sure showed sewer, etc. I’m hoping Grady’s book is a Richard Scarry book for grownups. Congrats on the book Grady. I can’t wait to get my hands on a copy.

[@hedgehog3180]

5:10 on that subject you might love a major ecological restoration that happened here in the 2000s, Egåengsø was originally a marshy area that was drained to make way for farming but in the 2000s it was instead converted back into a lake to help combat oxygen deprivation in the Århus bay. The slow moving lake functions as a giant natural cleaning facility that takes out fertilizers in the runoff from farms before it ever reaches the ocean and has been successful in restoring the natural environment in the bay, and at the same time it has also created a massive natural environment right on the edge of the city which has unmatched biodiversity. On any given day you'll be able to see dozens of different types of birds hanging out in the shallow lake and it has also been successfully integrated with the farms in the area around the lake. They keep cattle almost exclusively which actually contributes to the biodiversity since they both control the spread of some plants by grazing on them but also just by walking around they mash down the plants and create a marshy earth. And of course the entire lake is surrounded by a biking and hiking trail that's part of the wider bike path network in Århus and the national hiking trails and along it there are rest stops and look out towers for bird watchers making it a really nice place to go for a walk on any day of the year, from where I live it's actually only a few minutes on bike to get to the lake.

[@thegrumpytexan]

As a fellow Texan and engineer (though not civil) who lives not too terribly far from Grady and has both an oil pipeline and overhead electrical running through my property it sure is nice to see some of this. The oil pipeline goes to a tank farm (with interesting geodesic domes on them.) I pre-ordered the book after seeing the electrical grid preview - the illustrations are perfect to get my 7 year old interested, especially after one of his "teachers" at school claimed he didn't know what he was talking about when he told the teacher the tube up on a power pole is a "transformer" - she genuinely thought it was a battery! Some of your subjects I know - and now I know even better thanks to you, Grady. A lot of people don't realize just how much work was put into our world to make it as stable and comfortable as it is!

@@FidgetyGuy Yeah, anyone that's watched Practical Engineering (including me) is already aware the recycled water isn't potable. You're talking about breathing in faecal matter while you're playing golf or mowing the lawn; hardly an accurate statement. Since we're essentially talking about the risk of disease transmission I think you should be more concerned with touching a door handle in a public location, turning on a traditional tap/faucet in a public bathroom or grabbing the overhead handle in a public bus/train/subway than about being near any location using recycled water like this.

[@elijah4606]

I think it would be a public good to present the best arguments for and against certain types of public infrastructure! Why might it be good to build a pipeline, or why might it be bad? Why might a new road be necessary, or why might it not be?

[@Trixtah]

Perhaps you need to look at the title of the book and some of other Grady's videos, because I don't know why you're complaining. The last I saw, dams (especially the big ones), bridges, electrical substations, flood control and soil dynamics aren't exclusive to cities. In fact, I'd say that the vast majority of Grady's channel is about structures that aren't exclusive to cities.

[@Trixtah]

@@elijah4606 But that's not what this channel's about? Grady certainly explains why one option might be used over another in a practical sense, but his channel is about HOW things work, not about what are essentially political decisions re why Mega Polluting Pipeline "needs" to exist. Although he's certainly discussed the results of certain political decisions, in terms of how they affect the infrastructure. Including in this very video - San Antonio changing their flood control outlet and downstream waterway from a big concrete channel to a more natural waterway and parklands. But he didn't say WHY the city decided to go that route (I mean, it's glaringly obvious to me, but those decisions aren't really germane to the discussion).

[@iwanttwoscoops]

you sound a little defensive there bud...and you're wrong. Problems in cities inherently involve massive numbers of people in a very dense environment, while rural life has FAR more margin of error. As such, urban engineering becomes more complex and interesting, while rural systems can often be fixed with "divert it through those other woods lol"

Very cool, every city has unique infrastructure projects that no one else knows about but finding out about them is hard, also other country specific things like electrical infrastructure etc. I wish you or someone would do a series on other cities and their unique projects. My own city has the worlds largest (At least it used to a couple years ago) thermal solar array for use in the city wide district heating network. Gas flows through the solar thermal panels because it's easier to pump which is then connected to a heat exchanger connected to the closed loop district heating network. They use the chemical Uranin (Fluorescein) which is a florescent green chemical in the water so it's easy to spot a leak. So if green florescent water starts coming out of your tap you know you have a leak somewhere possibly in the heat exchanger in your house that is used to heat the incoming cold water supply line.

[@edythethompson7671]

I appreciate this video on the flood control measures in San Antonio. My grandfather was city engineer in the late 1950s-early 1960s and was heavily involved in flood control for the City. It was before I was born, but I heard stories about his work there. Thank you for the memories.

[@alexplorer]

I like the term "recycled water." Although what we do at home is technically a "gray water" system, I always say "recycled water" so people intuitively understand that the water has been used once and is getting a 2nd use before it is disposed of. For example, the washing machine is used to water the lawn/trees. The lint is filtered out, and we use Ecos rather than anything like powdered detergents that contain sodium. The bath water is also sent out sometimes to water trees on the opposite side of the house from the rest, but most of the bath water is simply used for flushing toilets. You definitely don't need to use clean drinking water to flush your waste!

[@risili5446]

Tell us more about your gray water system at home. My impression is that it's not _very_ common, e.g. even in ever more expensive homes of California. How do you turn a home into utilizing gray water?

[@alexplorer]

@@risili5446 Let me put it more generally: To move water you need to use energy. That's from one of 3 ways: Gravity, electric pumps, and/or manually. My washer is upstairs, so I have it drain into a "buffer" barrel that then uses a garden hose to transfer the water out the window directly to a rain barrel, which then uses drip hoses (with Y-splitters) to distribute it to the yard, trees, garden, etc. For bath water I sometimes use a sump pump to run it out the window to a pipe going to another rain barrel, then from there to the tree/yard on that side of the house. Mostly the bath water is transferred manually into the toilet tank after each flush. We use (ironically) cat litter bottles bc they have a large "mouth" so you can move them easily. There's more than one tank-full of water in each bottle. The kids fill them after they bathe. You can use a bucket. This is incredibly low-tech, and the only modification is I take the lid off the toilet tank and close the supply valve. Probably only saves a small amount of $ bc water is cheap, but it saves a lot of water. Just the toilet is >1000 gallons per year (1.5 gal per flush x 365 days x # of flushes/day). The specifics of how you do things depends on the layout of your house, yard, etc. For example, if your washer is by an exterior wall on a house with siding, then it's easy to run a line out. If you have a pier and beam house, you similarly might be able to access plumbing with no digging, and then run lines out to a distribution network.

Not a compression artifact, that would smear the colours at the edges. With high probabilities, it is a defective CMOS sensor, which can't manage some excess UV coming from the sky.

[@webmastercorey]

Just ordered one for my son's 4th birthday! He's very much into how things work. Happy to support your dream too. Congrats! 🎉

[@QuantumHistorian]

This was nice, but I much prefer your videos where you explain the principle behind things, rather than just pretty pictures of examples.

[@rmyers99]

Grady, your passion for this topic has long inspired me to take an interest in the world around me and I look forward to the book. Love watching you nerd out about water management.

[@thesweetone]

Thanks Grady, really fascinating. I come from an area where fresh water is ... everywhere, it actually becomes an issue for several months of the year ... like now where ground water covers 3 quarters of an acre of my 2 acre property (normally there is no surface water). Even during a severe drought about 7 years ago where we didn't get rain for 4 months with 35degree sun (over 100F) i had water 4 feet below grade in my well while others went bone dry.

I have lived in and around San Antonio all my life and I didn't know that we had an underground tunnel for flood waters. Reminds me of a short documentary I saw about an underground flood project in Japan. I think I saw part of it used in a movie recently. Keep up the good work!

[@adamgonzalez7450]

I’ve lived in San Antonio for two decades and didn’t know this! Great video!!

[@j-hon8202]

Preordered immediately. I’m a civil engineer graduate and walking round London since uni has given me a new perspective of how we do things, and the sheer genius behind it all

[@JonathanAlexanderM]

Engineers deserve way more credit than what’s already given to them. Taking the natural world and making it safer and better for so many people around the globe.💫

[@michaeldrainer2299]

Grady, thanks for all your hard work. Your videos are excellent and the book will be a great compliment to these efforts. I just placed my order and will be giving it to my 10yr old son for Christmas. We have discussions almost daily about infrastructure while driving down the road. I’m certain we will enjoy it together.

[@oksowhat]

as an engineering student i would certainly like to read the book, and will advise others to do so, persuing engineering has certainly changed my perspective of our modern world,

[@guavamnia]

Thanks for this video! I moved to San Antonio a little over four years ago and appreciate you doing a video that features my new hometown. I would love to see more videos like this!

[@Martititi]

[Correction: the issue was later fixed] I'm pretty sad the signed copy can't be ordered outside the US. Good job on writing this book nonetheless! I'll be sure to read it as soon as it's issued!

[@PracticalEngineeringChannel]

Fixed!

[@Martititi]

​@@PracticalEngineeringChannel You're the best! Big thanks for all your work from a civil engineering student in France! Have a good one.

[@brentjames9388]

As a plumber / pipe fitter in southwestern Ontario who has worked on many large projects can really appreciate the forward thinking of your engineering department.

[@metamorphiczeolite]

Grady, I really appreciate you and your campaign to make the world appreciate infrastructure. I’m an engineering geologist who works on infrastructure so I know how fascinating infrastructure is! I preordered your book. Thanks for sharing the results of your hard work!

[@ThunderChasers]

Been watching your channel for a while. I'm barely a minute in, and hearing my home city and seeing it in your video is so cool. Can't wait to watch the rest.

[@EricPagendarm]

I look forward to these videos every time they come out. Genuinely I think every single one has been worth watching. As someone who loves knowing how things work, your content has given such an improved appreciation for the constructed world.

[@knightshousegames]

I was expecting the outtake at the end to be the camera zooming out and revealing you were wearing wading boots and wading out of the middle of the river The excitement for this project feels very obvious as you speak about it, seeing someone reveal a big project like this is always exciting, and I hope it goes well

[@1babysag]

I was just in your city this week on business. I had no idea that you lived there. I have enjoyed your series very much. My bother is an engineer and his specialty is water reclamation. He is not nearly as good at explaining things as you are. I am glad to see that you have a book coming out. It will make a perfect gift. Keep up the good work.

[@antics562]

just pre-ordered the book! Happy to support the channel and looking forward to spotting all the engineering structures in my city that I might have glossed over in the past

[@LKSbethebest]

Found you a few days ago, bought your book immediately. Thank you for the high quality content in these trying times :)

[@cooperkinsley3254]

Grady your stuff has really helped me get interested in my future major and all of your stuff is amazing! Knowing you live in San Antonio too is awesome!

[@rogerburner3577]

I lived in San Antonio for almost 20 yrs till I went into the military and didn't know about some of those things. Awesome video!!!!!!!!

[@jackkern1215]

Grady, thanks for what you do so well, explaining complex topics in an understandable way. As engineers we tend to focus on our areas of expertise and being able to vicariously explored other disciplines is a real treat. I’ve pre-ordered your book and am very much looking forward to it. One infrastructure project you might find interesting is the Orlando Wetlands Park which is a large man-made wetland that provides secondary treatment for much of Orlando’s waste water removing nutrients before it’s released. No large structures but a very effective treatment facility that has also become a haven for wildlife and even a tourist attraction.

[@reidcushman3562]

You are as always a fantastic ambassador for the amazing (yet practical) engineering all around us that we so often take totally for granted. But also this time a fine ambassador for San Antonio. I wish I had known about this the last time I visited. If I come back again..... And I'm definitely buying the book.

[@alimaleki217]

I love these types of books/videos; after all, that's why I watch your channel! Ordered from No Starch Press; can't wait to get it! What to do till September?

[@MbreezySV]

Watched one video and had to preorder your book. As a mechanical engineer this stuff intrigues me so much as there much we never even discuss in school with regards to these types of infrastructures.

[@gates10611]

Big fan of the channel since you launched it. Stay true to your dreams, love your passion and rejoice in your success. Pre ordering books is huge yall let's help our favorite engineer out

[@CymruCreator]

Yay! an advert! congrats on your book Grady and thanks for telling us about it. Some youtube channels are pretty good at making ads relevant and interesting and you always do a good job. I always enjoy your ad section because it's authentically delivered and doesn't feel like a script read. Nice tour of your town too. It's inspired me a little, as I love travel but rarely get to do it, but I'm realising there's so much to see that you might not otherwise consider.

[@JHBVDS]

Usually I don't share "Marketing Material", but knowing what Grady does and how he can tickle curious minds, I will definitely share this!! Good Job, Congratulations Grady!

[@mike74624]

Congrats! a job well done. This book is going to be a much needed eye opener for very important aspects of our modern life. And because these structures and facilities work very smooth and efficient they are faded in the background without the well deserved recognition and appreciation.

[@shakenbakejake25]

I live in San Antonio and have driven by that so many times going by 281. When I found out you lived in San Antonio I definitely had to check out the rest of your vids, love your work!

[@Mr3ff]

Very proud of you! Your channel is a top tier gem on KZbin, the book should no doubt be a big hit!

[@GARDNSOUND]

Preordered! Stoked to support you and your awesome videos.

[@jacobshaw808]

I’ll be super excited to buy your book! You do such a great job explaining complex topics for the layman without unnecessarily oversimplifying. You’d make a great textbook author or college prof IMO

[@Bilbobobpie]

Just pre-ordered my copy! Can't wait! So exciting and great to see you expanding in this way!

[@flyboyx8288]

You literally make the best videos and do an excellent job of producing your content. please keep up the fantastic work. I would say they are about as professional as it gets without being done by a television team.

[@EngineeringwithDrKelseyJoy]

Amazing video! I remember finding it fascinating when I lived in Florida that I had two water sources at my house - 1 standard tap water for the house and the other reclaimed water for the sprinkler system at the house. I always find WWTPs and how different communities handle wastewater intriguing!

[@Ralesk]

Great news about the book :) And congrats on making this big and this far here on KZbin, you make a part of engineering approachable and understandable for people that really isn't otherwise.

[@J.D.E]

Your excitement makes me smile. Keep up the great work! Love the videos!

[@Adam_Malkovich]

Preorders book because I am always excited to see new Practical Engineering videos posted and am always engaged by the content. My brother is in school for engineering and wants to be an aerospace engineer, so I’ve taken an interest in his field because I at least want some understanding. Plus I think the book will be great when I have a family. Thanks for the amazing content and keep it up!

[@armyflyboy2006]

I have ran those trails many times. Thank you for making this vid Grady! Your first on-site vid is a hit!

[@tbboardhed2]

This is so cool, I moved to San Antonio about a year ago so still learning new thing about the city. Thank you for making the video. Gives me something to go look at. 👍👍👍👍

[@ThatBBShopSound]

Book pre-ordered! I love your channel! Keep educating the world, my friend!

[@stephanieparker1250]

I’m mesmerized by your excitement over engineering, I love it! I can’t wait to get your book!

[@caleballen4721]

So happy to hear about your book! I'm placing an order now. It reminds me of my favorite childhood book, The Way Things Work! Really shaped me as a person, so getting your encyclopedic style engineering book is a no brainer for me
