How Do They Do That? H20 Edition

 Admit it.  You've often looked at them and wonder how they work.  You see them so much that you don't even notice them as your senses automatically ignore them.  I am talking of course, about water towers.  A really smart dude, Dr. Neal Degrasse Tyson, explains more than you ever wanted to know about water towers in this short video. Enjoy.

Very elementary but interesting information. Where was this guy when I took science in school?

I second this: A really smart dude, Dr. Neal Degrasse Tyson.
Wonder if he knows anything about Astrophysics?

Always enjoy his scientific talks. Politics and religion not so much, but I listen and accept his views.

Let me take this opportunity to remind everyone that the City of Brandon built a water tower that blocks critical weather radar infrastructure from providing early warning capabilities.

Let me take this opportunity to remind everyone that Rankin folks are not the brightest bulbs on the Christmas tree or they would have had a professional involved that understands the concept of blocking signals. And that’s all I got to say about that.

I understand that people don't know the math, but does anyone really not know this principle?

For an interesting example of pumping and reservoirs, see

I remember when the water tower around the intersection of Watkins Drive and Forrest Ave ( a block or two from Lake Hico) just collapsed one night back in the 1960's.

It was like pouring ten gallons of water on an 8 inch ant hill.

Nothing left of many homes. I believe there may have even been a couple of fatalities.

The City of Jackson rebuilt the tower in the same spot.
(It still stands across from Holy Family Church/School).

I am now retired, but I worked as a Critical Systems Engineer, for a major pharmaceutical company many years back. We had a 750,000 gal tower at the plant. Once a year (during shutdown), as the low seniority guy, I would climb the tower, and go through the man cover in the top of the tank (way up in the air).

I carried a small inflatable raft in a pack, blew it up with CO2 and lowered myself into the absolutely full tank with a paddle and a bright light. I would paddle around and around, inspecting the inside of the tank with my light, while they slowly lowered the water level by draining the tank. When the large part of the tank emptied, I would go down the standpipe in my raft and finally exit the tower through the man cover at the bottom of the standpipe. The job took a full (long) day, and met FDA requirements for water tower maintenance. During the four years I did this annual inspection, we never found any problems. Needless to say claustrophobia did not work with this task.

Not so with the 8,000 gallon horizonal "USP Water for Injection" 316-stainless steel tank on the roof of the plant. It was usually cracked in multiple places (Distilled water is rather corrosive) and had to be TIG welded, then passivated (Chemically cleaned) before going back into use each year.

Old memories....

Thank you 6:44 PM !

That is a great story ! You are from a generation of real men.

Seriously. I suspect most high school graduates with a small interest in physics could have explained that. 🤷‍♂️

Let me remind you, Remind you: "An interlocal agreement has allowed the federal government to use a site free of charge for the doppler radar since 2002.

“We communicated that four years ago when we found another site or two and took them to it to try to relocate it or just raise it you could go up another 20 feet and it wouldn’t be a problem at all,” said Mayor Lee. “Yet they haven’t been able to find the funding at all. So the last city election in 2017 — The mayor and board were elected. We did not re-ratified that agreement. “

Furthermore: "Bill Parker with NOAA said the new Brandon water tower is blocking a few southwest radials, but they do have neighboring radars that can be used to meet the NWS mission to protect life and property. They will use radars such as Fort Polk, Monroe and Lake Charles to help fill in the gaps where data is lost."

So, the Feds had free use, years of notice, and are still able to function. Cry me a river.

In the early 70's they built a new water tower in Iuka, MS. The first time they filled it the tank overflowed. After investigating they determined that the pump had not switched off because the water was so pure it do not conduct electricity from one probe to another as required to signal the pump to turn off. Not sure how they corrected for this. I assume if the probes were moved close enough together the switch would activate.

In the 1940's and 50's small tanks (say 200,000 gal) would often have conical tops. Like an upside down funnel.

In Corinth in the early 1950's they had an ice storm so cold for so long that the ice in the tank lifted the top off a water tower.

I'm more concerned with the use of the term FIRE HYDRANT on the 'captcha prove you're not a robot' exercise on this page. FIRE never comes out of those things. They are WATER hydrants!

I hope 6:44 finally got some seniority. That was a shit job.

@ 3:32:

Since the Definition of "hydrant" is "a discharge pipe with a valve and spout at which water may be drawn from a water main (as for fighting fires)," the term "water hydrant" is redundant, but if it's a hydrant for use in firefighting, then "fire hydrant" is appropriate.

Trollfest '09

Trollfest '07 was such a success that Jackson Jambalaya will once again host Trollfest '09. Catch this great event which will leave NE Jackson & Fondren in flames. Othor Cain and his band, The Black Power Structure headline the night while Sonjay Poontang returns for an encore performance. Former Frank Melton bodyguard Marcus Wright makes his premier appearance at Trollfest singing "I'm a Sweet Transvestite" from "The Rocky Horror Picture Show." Kamikaze will sing his new hit, “How I sold out to da Man.” Robbie Bell again performs: “Mamas, don't let your babies grow up to be Bells” and “Any friend of Ed Peters is a friend of mine”. After the show, Ms. Bell will autograph copies of her mug shot photos. In a salute to “Dancing with the Stars”, Ms. Bell and Hinds County District Attorney Robert Smith will dance the Wango Tango.

Wrestling returns, except this time it will be a Battle Royal with Othor Cain, Ben Allen, Kim Wade, Haley Fisackerly, Alan Lange, and “Big Cat” Donna Ladd all in the ring at the same time. The Battle Royal will be in a steel cage, no time limit, no referee, and the losers must leave town. Marshand Crisler will be the honorary referee (as it gives him a title without actually having to do anything).


Meet KIM Waaaaaade at the Entergy Tent. For five pesos, Kim will sell you a chance to win a deed to a crack house on Ridgeway Street stuffed in the Howard Industries pinata. Don't worry if the pinata is beaten to shreds, as Mr. Wade has Jose, Emmanuel, and Carlos, all illegal immigrants, available as replacements for the it. Upon leaving the Entergy tent, fig leaves will be available in case Entergy literally takes everything you have as part of its Trollfest ticket price adjustment charge.

Donna Ladd of The Jackson Free Press will give several classes on learning how to write. Smearing, writing without factchecking, and reporting only one side of a story will be covered. A donation to pay their taxes will be accepted and she will be signing copies of their former federal tax liens. Ms. Ladd will give a dramatic reading of her two award-winning essays (They received The Jackson Free Press "Best Of" awards.) "Why everything is always about me" and "Why I cover murders better than anyone else in Jackson".

In the spirit of helping those who are less fortunate, Trollfest '09 adopts a cause for which a portion of the proceeds and donations will be donated: Keeping Frank Melton in his home. The “Keep Frank Melton From Being Homeless” booth will sell chances for five dollars to pin the tail on the jackass. John Reeves has graciously volunteered to be the jackass for this honorable excursion into saving Frank's ass. What's an ass between two friends after all? If Mr. Reeves is unable to um, perform, Speaker Billy McCoy has also volunteered as when the word “jackass” was mentioned he immediately ran as fast as he could to sign up.


In order to help clean up the legal profession, Adam Kilgore of the Mississippi Bar will be giving away free, round-trip plane tickets to the North Pole where they keep their bar complaint forms (which are NOT available online). If you don't want to go to the North Pole, you can enjoy Brant Brantley's (of the Mississippi Commission on Judicial Performance) free guided tours of the quicksand field over by High Street where all complaints against judges disappear. If for some reason you are unable to control yourself, never fear; Judge Houston Patton will operate his jail where no lawyers are needed or allowed as you just sit there for minutes... hours.... months...years until he decides he is tired of you sitting in his jail. Do not think Judge Patton is a bad judge however as he plans to serve free Mad Dog 20/20 to all inmates.

Trollfest '09 is a pet-friendly event as well. Feel free to bring your dog with you and do not worry if your pet gets hungry, as employees of the Jackson Zoo will be on hand to provide some of their animals as food when it gets to be feeding time for your little loved one.

Relax at the Fox News Tent. Since there are only three blonde reporters in Jackson (being blonde is a requirement for working at Fox News), Megan and Kathryn from WAPT and Wendy from WLBT will be on loan to Fox. To gain admittance to the VIP section, bring either your Republican Party ID card or a Rebel Flag. Bringing both and a torn-up Obama yard sign will entitle you to free drinks served by Megan, Wendy, and Kathryn. Get your tickets now. Since this is an event for trolls, no ID is required. Just bring the hate. Bring the family, Trollfest '09 is for EVERYONE!!!

This is definitely a Beaver production.
