In some cases, it just stops being feasible to chase the slope of a sewer farther and farther below the ground surface. A good alternative is to install a pumping station that can lift raw sewage from its depths back closer to the surface. Lift stations can be small installations designed to handle a few apartment complexes or massive capital projects that pump significant portions of a city's total wastewater flow.

Please don't stop the garage micro-implementations. I know it takes time to build them for little screen time, but it's a major feature of your channel!

Another reason to rely on gravity is you want to minimize the pressurization of sewage to prevent it leaking out. When I started in SCADA work I was told "In the event of a shitsplosion, close your eyes and mouth." Great video, thank you!

About 15 years ago now, I was working with a construction group that was refurbishing and remodeling a bunch of houses in an older neighborhood in town. After that project had petered out, I became the go to plumber for many of the residents. We got a call for a stopped up drain and realized that the problem was in the home's main drain line. We worked on that drain for HOURS and finally got it flowing... for about a day or so. When he came back to do the drain clearing dance all over again, the next door neighbor said his house was backing up. And then the guy from across the alley said the same thing. Turned out that in the alley, under about 5 feet of built up gravel and dirt was a large manhole that lead to a grinder pump in a tiny little lifting station. The city's water company had no idea that pump was even there. Turned out that the pump had been installed somewhere around 1904 and had been doing its job unnoticed and without any maintenance until 2007 when it finally seized up tighter than Fort Knox. Anyway, they came with a pump truck to clear out the area then installed a brand new pump for that little station that handles about 12 single family houses. I bet the new pump won't last 100 years though.

I wish that Grady's videos would be routinely watched by school kids. We expect kids to get some education about civics, government, etc., but wouldn't it be a fine thing for them to also get some awareness of civil engineering. "Where does poop go?" is a completely reasonable and important topic for civil society to understand.

As a professional engineer who has been designing, constructing and operating lift stations, sewers and wastewater treatment plants for over three decades, I appreciate the content of this video. Thanks, Grady!

Yahoo! I spent over 20 years maintaining lift stations in the small Pacific Northwest city where I lived. I was very enthusiastic about showing off the machinery we used to keep the flow moving towards the treatment plant.
A funny story- I showed a city council member one of our lift stations and he was shocked with the amount of machinery and expensive equipment that was stuffed into this small brick building. He commented that he he assumed that those brick buildings were just fancy equipment sheds and break rooms for us city employees. OMG! This guy had been part of the decision making process for our budget for years!! I was glad I was able to explain where that money went to every year.
If you don’t think infrastructure is important, try living in your city or town without it.✊

As an odor control equipment engineer the last part is particularly fun. From the sewage gas that would blow the manhole covers in LA to the horizontal sewage lines in the north Carolina that run on a giant vacuum pump I've seen plenty of systems that need fun ways to treat that smelly air. It's not a sexy job but we get it done.

Great video! Dealing regularly with molten gob of "pump killer" dental floss which people often flush down the toilet... On par or worse than "flushable" wipes. Confined space entry to clean screens is truly a thankless job. Thanks to all the wastewater infrastructure maintenance ops for keeping the product return department flowing!!!

The production quality upgrades haven't gone unnoticed.

Big shout-out to all the Engineers & Technicians who keep the systems running! As one Wastewater Engineer quipped, " It may look like s**t to you, but it's bread & butter to us!"

Would love to see a video about the massive raw sewage spill into the ocean that happened recently in Los Angeles. It was several million gallons of raw sewage. What happened, what went wrong, what is being done to make sure it doesn’t happen again etc. kind of like the videos you did on the Memphis bridge or the Texas power grid failure

As a sanitation senior pumping plant operator I appreciate you making this and other sewer related videos. I show them to the new guys, and it saves a ton of questions.

When we built our 'new' home (19 years ago), the builder cautioned us that because the lot was a the bottom of a hill, the home would require a 'grinder pump' aka 'macerator pump' to move sewage from our basement through a force main up to the top of the hill about a block away. I was initially hesitant, but in retrospect it has worked very well. The predicted MTTF for the pump is ten years; it went 14 years before it actually failed, but when that happened, it was an immediate crisis. Fortunately, the company that services that equipment in our area was able to replace it within about two hours of when we first called for help. They are noisy, and during a power outage, we know that we can only flush the toiled about 45 times before the reservoir is full. Fortunately, that is a rare occurrence and has only been a real problem one time since we have lived here.

Thank you, Grady, for bringing to light some unsung heroes and the equipment they build/maintain. And thank goodness for people willing to do the work of those two workers who were literally knee-deep in sewage, with their ventilators and waders on!

Excellent video, Grady! It sure did bring back some memories.
In another life (young and dumb learning furiously fast) I installed a few new lift stations. That was nice, actually.
But...when we (the contractor) was required to remove and reset a lift station, seems everybody else had suddenly somewhere else to be. Being the PM, Foreman, and everything else from operator to carpenter to electrician, I could have directed someone to do it, but I have always been the kind of guy who will not ask someone else to do something distasteful or difficult if I was not willing to show that I would do it. So I did. Yuck!!!! Remote Alaska work. I mean, really remote!! In the sticks, so to speak. It was us or no one.
So we pumped out what we could, or I did, and then cleaned the basin by glove and respirator, dismantled the lift station and all the floats, cleaned everything and did maintenance on the moving parts. New sensors and floats, new impeller, check valves, and yes; a new screen on the inlet side sloped from the inlet side at the bottom toward the output side on the top of the barrel. We made a new lid with two manholes and replaced the upper segment which was a partial cone, with another barrel segment and raised the top of the lift station without moving the bottom. Now the lift station could be maintained by locals (or so one would think!) by scraping the grate from the input manhole, and the valves, floats, (except two on the inlet side) pump and power from the other manhole. As far as I know, that crap is still flowing.

You would think the government would prevent companies for falsely advertising wipes as "flushable."

I think the most fascinating part of this whole video for me was the fact that kitchen sink disposal grinders have enough head to pump that high. I never realized they were such effective pumps.

Never thought I'd be this immersed in a video about sewege. But, here I am, utterly amazed.

I have been interning for a civil engineering water resources company in Southern California for the past 4 months and all I’ve worked on thus far is sewer systems. I still haven’t drawn any lift stations, but i have been reviewing the plans and your video has significantly cleared some misunderstandings i had. Many of the project managers are too preoccupied to explain the nitty gritty to an intern and so i diverted to online learning (youtube). And boy i am glad i found your channel. Thank you man. Seriously, please be like a professor or something, you are so good at explaining this stuff.
