New Orleans Drainage Infrastructure Tour

[@shAnn0n1]

This was so revealing to me. With hurricane Ida coming to shore ,this was amazing to see. To learn about New Orleans and the drainage systems and the pumping systems was eye opening. The way you guys explained everything was great and so easy to understand. Thank you.

[@timothybmonahan]

This is a fantastic, detailed explanation of a fascinating system. We take the engineered system for granted, so few actually understand how this works. Thanks for enlightening me.

[@MS-37]

Those rain gardens seem like a good idea. They should put small scale ones all over the city.

[@tdubblz]

This stuff is so fascinating to me. I’ve been curious since a kid on the Broad bus passing by pumping stations

[@g110]

New orleans is a special place thanks for explaining everything so simply!

[@Hal-yc9jd]

Amazing video. Thank you so much for sharing and educating

[@theGoogol]

Nice video. Greets from the Netherlands. God speed with Ida.

[@annbush1826]

thank you from a Katrina survivor. The wonderful Dutch engineers who came to help at that time must have been staggered when they realized how corrupt city officials had never permitted nor authorized funding to build locks to close entry from the infall canals.into the shallow lake. After Katrina, no one went to jail. However, the state set up the Southeast Flood Control Agency. Members include all parish presidents, and a civil engineer , a hydrologist and a geologist. Ida just made landfall, one million people are without electricity, and without tv or cell phones the population is being directed by politicians to boil the drinking water. Le tout c'a change, le tout c'est le meme chose. Ann Bush, author "Katrina:10 Years On"

[@spacecat7247]

It's a group of cool concepts but a major uphill battle. 1 or 2 hiccups and calamity strikes with vengeance.

[@luigivettori]

This is great info! Nice job explaining.

[@scottbertus]

Drone footage of the pumps pushing water down palmetto would be dope

[@theshimonmor]

Highly informative and educational. Well done and thank you!

[@shanasmith1]

Excellent video. Thank you for helping me understand something that I didn’t fully understand.

[@nc4579]

This is extremely well done thank you so much!

[@shrimpxd9772]

Congratulations for this very informative and well-made video

[@rahmreekoo86]

Great video! Thank you for posting.

[@BinglybertSlaptyback]

This is EXCELLENT. Thank you.

[@nombreapellido9038]

What a great explanation. Thank you sir!

[@stratstrat644]

This video is fabulous. I really learned a bunch of things from this. Thanks!!

[@pursuit9827]

What a clear explanation!

[@kurtmanasco67]

I can remember my grandmother and her family talking about the pumping stations in New Orleans there father worked the pumping stations that was back in the early 1900s and he worked there back in the 1800s my grandmother said when she was younger that they broke the Leevies in Saint Bernard parish to save the city from flooding that same pumping station is the one that he worked at for 40 years so Yea with out the pumping stations there will be NO New Orleans sad to say that with the sea level Rising we are losing our Beautiful city but till then I'm staying here at home in New Orleans around City Park

[@markrobinson9384]

Sea level rising...sure it is, Plymouth Rock is still at sea level 400 years later.

[@yeremyjray3424]

Very informative. Thank you

[@9blucats]

Thank you for this.

[@chadsimmons6347]

The idea of building on mud is very strange to me we hit solid rock a few feet below the dirt

[@tonygaines15]

Awesome explanation video 👍🏾 Although....it seems to me that the "bowl" isn't a place that humans should live🤔

[@ianreynolds9081]

This was fantastic.

[@Bke14151]

This makes so much sense… He’s cool.

[@lodicfy7776]

Ratio

[@annbush1826]

Tulane's Casius Pealer here gives the clearest explanation of HOW water flows in New Orleans. This is why Katrina. This is how storm drains backed up so iron manhole covers blew up 8 feet into the air. The only point I would like to have seen added was that when Katrina forced the waters of the gulf of Mexico westward through the pass of the Rigolets, it caused that shallow lake to rise an estimated 15 feet. While Professor Pealer doesn't go into the massive combination of corruption and a vulnerable population, this is vital to understanding one of America's most fascinating cities. (A New Orleanian and a Katrina survivor)

[@loganbarry9661]

this is why im a virgin. watching these videos on my free time

[@alyse9673]

Not a virgin and still watching these videos on free time Lol It’s a great video

[@Angelo-fo8de]

He’s holding his own 😂

[@reelingwithrobby]

When you say that the water is trying to level out and in turn that how water gets into the canals, are fish able to pass through? Because I have caught literally some of the largest fish I’ve ever seen over 7 feet long in these canals, specifically near metarie. I always thought they just pushed water out to the lake. So fish have the ability to swim freely through the pipes? Because I have caught alligator gar that were over 50 years old in these canals and just have always thought that they were trapped in there

[@Patricia-kb5qv]

Very interesting, thanks!

[@Bke14151]

Great video

[@arnoldtx1]

Draining the swamp

[@thersbugb7362]

So the housing on New orleans in a swamp, Fllood zone?

[@MJGdaishi]

I'm struggling to reconcile the logic of the green retention basin there at the library. You have a water table that is above the current artificially maintained table created by the pumping stations. is the water not flowing through the ground toward the pumping stations where it gets pulled up and out anyway?

[@shstrn2001]

From what I understood in the video is that the water gardens will slow the process of the rain water entering the drainage system that leads to the pumping stations. So the water gardens will hold a decent amount from entering the drainage system to allow the remainder of the runoff to be pumped out of the city without the water that is being held in the water gardens adding to that amount being pumped.

[@billsimpson604]

The dryer the soil, the faster it sinks, as the organic material in it dries out and rots away. Except for along the River, that was all swamp and marsh. They built levees and drained the swamps for land to live on. New Orleans never became Houston or Atlanta because it is surrounded by water & swamps. High land is 30 miles away. That is too far for an easy commute across a bridge.

[@pierrenavaille4748]

Well, you're right. It does get pumped out eventually anyway. But, three things happen before it is. Engineers call it "detention." While it's raining, the amount of runoff is peaking at the catch basins and pump stations. When runoff is trapped in a rain garden or similar facility, it does not enter the drainage system at the peak, but is detained, and released slowly during the off-peak period when the system is better able to handle it. Meanwhile, the interstitial voids between the soil particles remain filled with water. This slows subsidence of non-organic soils and prevents air contact with organic materials in the soil. A lot of New Orleans' soil is organic, and contact with air causes the organics to rot, which reduces the soil volume and accelerates subsidence. Finally, the plants in the rain gardens and elsewhere draw up various pollutants and trap them in the cellular structure of the leaves and stems, preventing those pollutants from reaching Lake Pontchartrain and the Gulf of Mexico. Those pollutants include metal, petroleum products, and artificial fertilizers. Releasing them into the Lake puts them into the food chain. As they rise higher and higher in the food chain, they become dangerously concentrated, so we don't want that. Who is at the top of the food chain?: us.

[@paulidiomas]

@@pierrenavaille4748 I love it when an honest question gets a civilized answer. Thank you sir!

[@yomama8873]

Very interesting 😱👍👍

[@tdubblz]

So what I learned just now is find out the route of covert drains in a flood and you’ve found the stable ground you can walk on.

[@sams7655]

Hire oil drilling companies that do fracking. Pumping a slurry mix of mud into the ground and allowing it to build up pressure. The fracking process will solidify the deep underground foundation.

[@Bobby007D]

These people don't need levees , they need submarines.

[@provrob]

lots of bird life

[@leegilley221]

Let's see if it works now that Ida is here. Aug. 29, 2021

[@bradleylyle9607]

they need to try and make new swamps and cyprus trees

[@bbmw9029]

We need to question why such a large city is built on land below sea level. Maybe after Katrina, the flooded areas should not have been rebuilt as is, but the damaged buildings should have been torn down, and the Army Corps of Engineers should have pumped in river silt to build the land up well over sea level. At that point the land could be rebuilt on, and won't fill with water every time there's a major hurricane.

[@erikje7352]

great idea,s ,,,,, who told you those ? i mean it is kind of a radical shift in your way of thinking

[@adventureguy4119]

Why build a city like that?!?

[@billsimpson604]

The Port of New Orleans at the mouth of the Mississippi River which drains much or North America and carries an enormous amount of cargo.

[@Odin029]

If you look at a map of the US, you'll see that many rivers flow into Mississippi River. The river system has really defined much of US growth and history. Chicago became a huge important city, because it's location connected the rail heads, to the Great Lakes, to the Mississippi River. Look at all the major cities that sit on rivers that drain into the Mississippi, from Pittsburgh to Kansas City, to Little Rock and Omaha. Even today huge amounts of cargo are sent from place to place on the river system in the US, and what city sits at the mouth of the Mississippi river connecting that cargo to the rest of the world... New Orleans.

[@jrtstrategicapital560]

Why would anyone spend anymore funds to keep the inevitable of rising sea levels from occurring.? The truth is..New Orleans is doomed to be an underwater city . You can build a whole new city in a better location for the amount being wasted on this very short term and short sighted , very temporary fix.

[@woowooNeedsFaith]

... benefits of living on swamp.

[@chrischupp9760]

If the lake is full it doesn’t work

[@pierrenavaille4748]

The Lake is part of Gulf of Mexico. It is never "full."

[@KevanRice]

wasted energy hydro turhine on discharge turning generattor

[@gesmith7402]

There drain storage is still shitty

[@guymann4016]

Should we start the process of migrating out of the city and just let it go? I mean, is it really worth it? I get we’re talking about people’s lives and homes etc but the billions of dollars we funnel to this stuff is so wasteful.

[@lesterjohnson2621]

To do what??? Because it's really just new Orleans thats under water wat about the ppl south like in the plaquemines or jus uptown.....and its not the only city that's in trouble.....venice, miami...new york.....don't get me started on the Netherlands as a whole lol but you would have to accept that climate change is real so.......
