How Does A 3 Chamber Septic Tank Work 
Развлечения
I came here because today i had to empty out my septic tank after 8 years of living in this house. Thanks for the lesson, its exactly how my septic tank and soak pit is built, I now know to also treat it better. I am in Kenya btw, we have borrowed most of our systems from England.
Great comment - thank you
To be clear, in the United States, a multiple compartment or "chambered" Septic Tank is NOT divided into equal parts... nor should it be. Typically, the 1st Compartment or Primary Chamber, is the biggest, because it's where the majority of the solids will separate from the liquid. The 2nd Compartment is usually where an Aeration Treatment Unit (ATU) or Aerobic Bacterial Generator (ABG) would be installed... basically an Air Pump, which oxygenates the Effluent. The 3rd Compartment or 3rd Chamber, which is usually the smallest, is where an Effluent Filter would be installed in the Outlet Baffle. The idea of a filter in the Outlet Baffle is to capture or trap any suspended particulates before they exit the tank, and flow to the Leaching Field or "soakaway" as you call it. The bottom line is the longer the wastewater stays in the tank, the better settling or separation between solids and liquids. In other words, it improves pretreatment of the Effluent, which can help the Leachfield or Drainfield last longer. In my opinion, multiple compartment tanks are a good idea, and having an Effluent Filter in the Outlet Baffle of the 3rd Compartment or 3rd Chamber, is usually not a problem, because it could take 3 or 4 years before it will need cleaning, and by then it's time to pump out the tank anyway. However, pumping a multiple compartment tank does cost more money, because it's more work and ultimately, a greater volume of wastewater that's pumped out, or extracted from each of the Septic Tanks compartments a.k.a. chambers.
Thanks Craig i have a little bit to decipher what you posted im completely in the dark with septic system's but learning as much ad possible, my question is when its pumped yearly or whenever what and why do we pump them out
Is it left over crap gunl that didn't degrade or shouldn't have been sent down there ? THANKS YOUR POST WAS A HUGE HELP IN MY CRASH COURSE IN THIS INTERESTING SYSTEM, im a chemical operator and understand the workings of lots of different systems like filtering and so on. 😉👍🏻👏🏻🇺🇸💩👈🏻
@@dawngregory6549 To be clear, I'm in the Northeast United States... New England. Specifically, I live and work in the State of New Hampshire, and I've been a Licensed Septic Professional for about 20 years. Obviously, in the Northeastern part of the US, we have lots of cold weather and more than a little snow. As a result, Concrete Septic Tanks are very common and still the most popular here in the New England area. I think it's probably because we know that Concrete Septic Tanks can easily last 50, 60, or even 70 years. That being said, proper care and maintenance of a Septic System requires pumping out your Septic Tank every 3 to 5 years, depending on the number of full time occupants living in the home. The reason for this, is because not all of the solid waste will be broken down or digested by the bacterial action in the tank. In other words, a Septic Tank is a bacterial environment, and the microbial activity in the tank essentially eats up and breaks down the poop and the paper, which creates sludge that accumulates in the bottom of the Septic Tank. As a result, the sludge needs to be removed by pumping the tank every few years, which allows the tank to return to it's full liquid volume... whatever that may be. Typically, it's at least a 1000 gallons, and frequently could be as much as 1500 gallons. The size of the tank is dictated by the number of bedrooms, because bedrooms dictate occupancy. In my state of New Hampshire, a 2 bedroom home requires a thousand gallon tank. Nevertheless, I'm a big fan of 2 Compartment Tanks or 2 Separate Tanks, because I believe the longer the wastewater or EFFLUENT, can be contained in the tank, the better separation of the solids. In addition, longer retention time allows the bacteria to break down the waste better, which can also improve the overall function of the system. Here in New Hampshire, 2 Compartment Septic Tanks and even 3 Compartment Septic Tanks have become very popular in the past decade or so, and I think it's the way to go, and it doesn't really have a big impact on the cost of a New Septic System either.
Well explained
Cheers Craig, I am currently constructing our home septic tank. Still in its primitive stages. Excavation works and you've just confirmed to me the ideal size of the tank and its longevity if maintained regularly. I have plans to develop our home into a double storey and the measurements of our septic tank is 3 metres length and 3 metres wide and 3 metres depth with 3 compartments. From Fiji. Vinaka!
@alipatetuberi7726 Good Morning and thank you... I'm glad some of the information I've shared has been helpful. To be fair, I'm obviously in the United States, and we do things differently than in the United Kingdom. We even do things differently from state to state and county to county because the geology changes. In other words, soil conditions and groundwater conditions are different from one location to another. As a result, in my state of New Hampshire, the environmental rules and regulations are specific to the typical or most common conditions we encounter in the Granite State. With this in mind, I don't know what you're facing for challenges wherever you are, but in my opinion, a 2 Compartment or 3 Compartment Septic Tank is never a bad idea. Again, the longer you can retain wastewater in the Septic Tank, the better your system should work. It improves Pretreatment of the Effluent, which means the solids or suspended particulates should separate and sink to the bottom of the tank. It also enhances bacterial action by allowing more time for the microbes to do their job. Remember, a Septic Tank is a bacterial environment, and without microbial activity, the system won't work. So, be kind to your Septic System, and make sure you always check labels when you shop, and only buy Septic Safe cleaning products... Alright?
who knew there would be a septic tank TV, let alone I'd be here watching my 5th video! As far as septic tanks go this is fantastic. I've been thinking about a self build in the middle of nowhere. A few hours on here and I feel primed! This got me thinking I could use the same strategy to filter raid / grey water too.
Thank you
Thank very much. I understood why three chambers are needed. That was good a plumbing lesson. Post some more on biogas from tye septic.
Am from South Sudan,I really enjoys and understand when your teaching.
Question
How do I design a septic tank for residential area of 10 occupants
Very very useful video ,sir. Thank you so much . watching from Sri Lanka .
Thanks for the clear explanation
Kindly advise if you dig the extra pit for the soakway
Thank you !! That is the best i have seen so far !! Gary K
Nice one 🙂, watching from Nairobi-Kenya
Very informative. Thank you.
love it. Nice one. Thanks for sharing your knowledge. I used for my building 25 years ago and looking for the design how I have done it. It recalls me again. Thanks again. Would you please let me know detail of the pipe used in chamber wall
Thank you
That suit makes talking about poop 💩 containment a bit more classy 😂😂
🤣
i really enjoyed this, thank you.
Thank you very much for sharing!
Very useful video, watching from South Africa
Thank you
Totally wrong design.
Is it possible to design the 3rd compartment in a way so that the water exits with a quality good enough to not contaminate a nearby aquifer?
Do you ever have to pump physically pump out chamber 1, or do the microbes eat all the solids?
Thanks... I will like to know what you put in the first chamber
Thankyou so much for the information
Very nice information. Thanks mate👍
Very Helpful. Thanks
:-)
Good job. following you from Nairobi -Kenya
Thank you for your comment :-)
Nice one
I borrowed your knowledge and did my own septic at my farm. im so happy its working so well.
You have explained it super and I have built one
Let me know about the 3rd chamber. Should it be kept in towards the road,,for easy access for cleaning or can it be built otherwise we also(more inside)?
Thank you septic tank guy
Great! Please one question i would like to know: what would be the fate of clean water at the third chamber? What would be constituents of clean water at third chamber? What about microorgansisms ? Thanks
Outlet pipe side is raised little bit due to soil erosion.
There is, a height difference between inlet and outlet pipe....
Water overflow is not taking place from outlet pipe.
Can I interchange inlet and outlet pipe
Iam using 3 layer plastic septic tank
Multiple septic tank idea is excellent. It would be more beneficial if Waste stuff get into septic tank thru the T built fittings can help to filter the waste water more cleaner then without fittings.
Favorite quotes: "Chamber one floats to the bottom" and "it's just like wine" Now I want one.
I was thinking same thing. I laughed out loud. Figured I wasn't the only person.
Thanks for the update and the way you explain things thanks once again for the efforts. Make me understand the concept👍🇩🇰🙏
Thank you
great stuff - well presented - keep em coming !
Thank you
Brilliant information, thank you.
Thank you
Hi Jason, can you do the video on soak aways please :-)
Great shit your doing lad
I have a 3 chamber tank its tilted had to make another inlet hole below the origanl one do i have to make another hole at the exit end lower than the one whats there now
Thank you very informative
Thank you x
Sir I have a doubt, in a 3 chamber septic tank the walls are at complete height... So how will the foul gases go out, coz uh even didn't mentioned abt vent pipe
Thanks man.
Most tanks now addays are plastic or fiber glass..you dont see concrete tanks much..but they still use them. Texas, Usa
about the to soakaway pipe. Where does it ends or how? Thank you very much for your time doing this video :)
Thankyou for your question. The soakaway pipe goes into something called the soakaway. The oakaway can vary in shape size and design. Here is another video I made that may help you: ruclips.net/video/YO15cgwaYdQ/видео.html
This is useful....currently building an apt building
Thank you for your comment :-)
Very interesting. I am thinking of constructing one wit 2 chambers but am convince with the 3. Can you talk more on the soakaway?
Soakaway is just where the liquid fluids as in water leave the 3 chamber system and exits to the rock, gravel or what is used or if used and into the soil. The soil absorbs the clean water, clean as in free of poo, tissue and debris, not clean as in drinking water. That's the whole purpose of the system. The 3 chambers trap all the debris so what is left is debris free clean water that is "soakedaway" by the soil. The soil soaks it up as like a paper towel does a spill on your kitchen table. If you left that paper towel there long enough, it would eventually dry out and can be used again to wipe up another spill. In the case of a septic system, the soil around the septic tank is likely to stay wet and damp and usually why you'll see much greener grass around your septic system.
Is the flooring needs to be cemented on all 3 chambers or not?
Thanks for the video... I’m a Brit living in the Philippines and have this type of tank. Not sure whether there is an outlet... which concerns me. The water company came to clean the tank in Jan, but now we are having sewage coming up through drains inside the house!! I’m think that the baffles may have blocked in the first chamber? Does that sound feasible?
Hi Alan, it sure does. Can you gain access to them?
Thanks
You have to ask the plumber who built and check it. Either the inlet or outlet pipe might have been blocked. It happened one time in one client who had the same problem as yours. What happened they dug up and found out the outlet pipe has been blocked.
@@bernierapirap6522 Thank you for your comment :-)
Hi Alan, did you try to install back flow preventer?
Very nice... From Bangladesh 👍
Hello Jason, Hello guys
Thanks for the video. Still I have a question. How do you manage the odours that come out the septic tank through the pipeline till the toilets. I live in a house built by my dad, where I encounter that problem. And when it starts it’s really unbearable. Thanks for helping.
When last did you disludge the tank? and ensure you don't fluch chemical substance down the drain, as it kills the microbial responsible for the decomposition of the waste.
Can you explain please why you use a tee shape pvc inside septic tank? Thanks in advance!
Thanks for your comment. The tee piece stops the fat, grease and the sludge from entering the soakaway.
Gracias.
top man top advice
Perfect
👋 HI, #1 chamber, the water will take about 6 months to get the first outlet ??
Thankz
thanks!
Please also describe in details about Soak pit work with water exit from it
Ok. Thanks
Totally wrong design. He is not engineer.
Very nice! Septic tanks are very interesting. There are so many different varieties. Just completed mine.
After this video, feel free to take a look.
Thanks for sharing.
Thank you for your comment :-)
Really good video.
1. If built like this... For a 3 bedroom 5 person occupied house, what should the size of the Chambers be?
2. How often will it fill up?
3. How do you avoid grease clogging up the inside of it?
75 gals per head. 75x5=375 gals Volume= 1.125+0.75x375gals=282.37 say 283 gals convert it to cubic meter 1cum=264gals 283 divide to 264=1.07 cum total discharge to get length Length=total volume divided by width x 1.20m depth. So you have 3 chambers. The first chamber would be 1.0 length x1.0m width x 1.20+(0.30m for air space to accommodate aerobic bacteria. The 1.20m depth is for anaerobic bacteria. These bacteria are essential for the breakdown and processing for waste material.) 2nd chamber is 0.5mL x 1.0mW x 1.20D+ 0.30m air space 3rd chamber would be the same size as the 2nd chamber. You total depth would be 1.50m. Thickness of walls are not included in this dimensions. To avoid grease going into the tank, use multiple chambered grease trap below your kitchen sink.
@@andreinicolaiamadeo3453 wow that's some answer!
Thanks for your comment.

A COMPLETE DESCRIPTION HOW TO BUILD THANKS FOR SHARING
Thanks for that
How many hallow blocks. Causes in 5ft, 3/3 square seftic tank and cements.
Please how can i get the book?
Hi Jason, I have designed a septic tank in AutoCad based on the information I got from your exelent video, The design I have put together has four chambers in total and built from reinforced concrete,. The reason is I want the water that finally comes out will be as clean as possible in regards to the soakaway. I'm a Brit living in the Philippines and living in the province where most of the drinking water comes from a well. How far would you recommend the soakaway is from the well so there is no cross-contamination and is there an email i can send you my design for a once over
30-50m
So well explained. I will do a 3 chamber septic tank just because of this video alone. Thankyou
It's better to separate the grey water from the toilet water, right?
How long will it take chamber 1 to fill and or do you have to wait for chamber 2 to fill up to empty out? Thanks in advance.
Thank you for your comment. About 24 hours
@@SepticTankTV I suppose John implied " filled up with debri"
what about the three chambered siphon tank by Philbrick circa 1883
Love from India
You have any schematics for a biononormaliser/biodigester for biogas harvesting.
I will try and dig some out
In which chember we should put the Gas pipe
Thanks ❤
You're welcome 😊
My air pump pipe goes into my second tank and I can hear it bubbling,but I can’t see any bubbles coming to the top..what’s the deal? It’s all working fine. No stinky water
There seems to be a huge piece of missing information. Why don't the solids in chamber one keep building up until they are above the connection to chamber 2? For that matter, why doesn't the entire thing fill with solid waste and become overwhelmed?
Bacteria and enzymes inside the septic tank break down the waste. That's the reason a properly sized tank is needed, so the tank can hold the solid waste first long enough for the bacteria to break them down before they get filled up.
The septic tank should be pumped out every 3 to 5 years - sooner when more occupants live in the home. In the U.S.A. pumping can cost about $500 where I lived, but doing so will prevent most future problems.
awesome

Welcome
what if the septic tank full and you want to pumping all things than 3rd chamber is clean properly but 1st and 2nd chamber will be not clean.... Any solution for that...
Septic tank worms
Can you please give dimensions for the 3 chamber septic tank?
Sure. It is 18 foot long. 18 foot high
@@SepticTankTV r u serious ?
clear.
If the soap water or detergent water enters septic tank does it kill the natural bacteria in present in septic tank.
Vineeth ( india)
Thank you for your comment :-)
it wont
It really depends on what type of detergents or soap that you use. For example "antibacterial" soap can and will kill bacteria in a Septic System. BLEACH is terrible for Septic Systems, so the bottom line is you need to check labels on all cleaning products when you shop. Make sure you only buy Septic Safe cleaning products, and the good news in America, is that the information is on the package... if you look for it.
🙏
From where gas will pass out ?
my septic outlet discharges yellow water. what shud i do to convert it into colorless
Thank you for your comment :-)
The reason could be that, the successive outlets from one chamber to the next are all in the same level hence no sediments settling in the previous chamber.
This allows fats, poo and scam to freely move to the next chamber, and that's a poor design.
This tank is how did use to long
Thanks
Propper pina-🍺men lol
How do we put bacteria in the septic tank??
Following. interested.
it's a natural bacteria that comes from our own feces. Called "Aerobic bacteria", said bacteria will grow overtime and naturally help breakdown solid materials in liquid waste. It's a fully natural process. Aerobic bacteria needs oxygen to grow and be active hence the septic tank's design to allow sufficient ventilation.

Although Septic tanks are good and they work effectively, l think we should reconsider our whole premise of whether to use Septic tanks at all because it is expensive to purchase but more over it is a waste of value resources in terms of compost.
Poo and urine make excellent compost and a way should rather be found to utilize this valuable commodity which essentially is recycling which is the woke buzzword nowadays apart from the term "Global Warming" which they discovered is not true so they changed the term to socalled "Climate Change" which is a better bullshit term because it can mean anything. When it's a hot summer they can say it's because of Climate Change and when it is a cold winter it's because of Climate Change. You can't ever be wrong. These wokes are very smart people.

Wrong information
You don't have proper knowledge on septic tank
It would be smart to construct an integrated wastewater treatment plant for 50 houses instead of doing all this huge separate individual nonsense. Of course, the wastewater treatment plant can be designed with the future development plan in mind. Say, after 10 or 20 years, a sewage treatment plant can be modified to a sewage treatment plant for 200 or 1000 houses, and so on. Waste of time and money and hugely negative impact on Mother Nature.
Not practical sorry, your channel is gives wrong information
The way you are telling is boring
