This soundtrack is unreasonably good for the septic tank episode.

[bobbofly]

I worked at a septic tank company in Roosevelt, UT back in the early 80s, & instead of rebar, we formed a heavy steel mesh that resembled sheep-tight fencing over the steel tank molds, having previously painted them with used motor oil as a release agent. I had the darkest tan those summers. We cast the tanks upsidedown with the center rectangular space-holder as a non removable, permanent part of the mold. The rest is pretty much the same.

This is the kind of information you didn't know you needed

[Kdschaak]

_The grass is always greener over the septic tank._

You need to do a follow-up video: "How It's Made: Septic Waste"

[Christopher-N]

This episode should have included just a bit more about how a septic tank works (with graphics), than what was provided in the beginning. Otherwise, this was a good video for its length.

they can also be used as hot-tubs / they stay warm even in the winter

I had no idea these were so manually labor intensive. I always assumed they were made by machine for the most part. Lots of man hours just to make one tank.

I use to work for a company that made big concrete boxes for under ground communication bunkers for ATT there are thousands of those boxes underground from one end of this country to the other. The cement mix these guys use would never pass structural integrity tests, waaay to wet! We poured our cement with very little slump and dry. We used stick vibrators to move the cement into the forms and covered them and steam cured them overnight. They were so hard in the morning that if you hit them with a hammer they would sing.

You overemphasized the role of the septic in the treatment train. The drainfield is by far where most the actual treatment is achieved. The tank is mostly to settle out solids.

We used to make burial vaults almost the same way….only we added a plastic additive to the concrete to help keep the shell completely waterproof…….the lids we poured an asphalt mixture so once installed the weight of the lid would seal it to the shell…….we would work all summer long building them, and just deliver them during the winter months…..using a small crane on our trucks to properly deliver…….

[Skeens]

Huh, I think I'll make one myself.

[clintonlyle]

I’m amazed at how the worker balanced that long piece of rebar on those vertical pieces. 👀

[TheInevitableMan]

"... using a radio remote-controlled knuckle-boom crane."

Say that 10 times fast lol

[jxxnmatt]

I thought it would also explain the process of how it works or what's used to maintain the waste.

[iparkedmycar]

Can't wait to see "How it's actually made" talk about "the vibrating stick" hahaha

[EveryoneIsFightingSomeBattle]

There was a septic system company that made sure they followed the 5 P's:
Proper
Planning
Prevents
Poor
Performance

[MikeStrip]

I like the line “the other worker consolidates the mixture with a vibrating stick.”

[KwatsanDarbinian]

And you smooth it out with a bunch of schleem. The schleem is then repurposed for later batches

[jodyjohnsen]

I knew these were cool but this is even better than I realized. Excellent!
