Reminds me of that classic story of the man hired to make London’s new Victorian Era sewer pipes. He wisely made them several times the diameter they needed, anticipating growth. He alone saved untold millions in future money. Edit: oh, was it Joeseph Bazalgette?
Yes, indeed it was. I believe his father was a French military engineer. The story of his fight to get this sewage system built is a truly amazing one. He is worthy of the highest honour. A most extraordinary gift to the UK.
@@chrismoyler we’re covering him in history now (I’m 16!) and the fight to create hygienic conditions for the general public was truly impossible seeming at times - something that never occurred to me before. Bearing in mind only a handful of people believed in germs when it was first built, the Bazalgette Sewer is really a miracle.
We could incorporate the principle of future-proofing into infrastructure designs as a basic standard... but we don't, because there seems to be a mentality of "make work" for the future, where we consider it more important to have jobs for people to do and to keep ourselves more consistent in pace of the economy or of growth... than to future proof things so they don't have to be worked on again for a long time. The daily cycle of jobs and money-flow keeps it so that we don't want to solve things on a long-term basis. We want a reason to keep the money flowing and the employment motivated, much like Apple scheduling the rollout of certain features over a number of years, so they have a reason to release a new version every year... or like Republicans wanting to campaign on the "border crisis", but not wanting to actually vote for a bill that solves it, because they want to have that issue to campaign on for as long as possible... we often see major projects broken up into "phases" or done in a "bare minimum for now, expanded in a few years when we need to" approach, to keep projects providing work and reason for funding for years to come. It's the same mentality that has created our disposable consumerist society, with everything designed to make you have to buy a new one again and again. We could just spend more money now (but less money overall in the long term, which capitalists will see as a long-term bad) and get it all done in one phase by hiring a lot of people to work on it at once, etc... but then what after? All those extra people hired to get it done faster are left without work afterwards, and there isn't always gonna be a major infrastructure project going on if we don't stagger ourselves and pace things out, so they might not have any projects to move onto. And now the money is spent, so how do we keep a consistent and/or ever-increasing amount of money flowing over a long-term period if it all gets spent in one lump-sum at once and then comparatively little-to-nothing for years in-between major projects? Under the current system, we seem to gravitate more towards doing things slower with smaller crews that can provide employment over a longer period and keep the flow of money more consistent and increasing over the long-term... time spent waiting for important projects to finish, be damned. A lot could be different if we didn't set up our entire economy/society around needing to be employed, or always allowing the money men to make the decisions.

@@jamesardron Oh for goodness sake's, grow a brain. Combined sewerage outflows (CSOs) are in no way the product of privatised water management. We had 100+ years of nationalised water industry management that pumped so much raw sewage straight into the sea that the EEC prosecuted the UK; the nationalised industry didn't bother repairing or replacing the old Victorian cast iron pipes, even after 1976 when your bath water was restricted to 4 inches & standpipes in the street became a thing, hose pipe bans were a regular feature of an English summer; CSOs were common & normal, no-one ever gave a damn. Many EU countries don't even bother to measure the amount of sewage that is released in CSOs. It is only because the industry is privatised that it has become a topic. Note the phrase "since 2020". If they were to be truly representative they would measure from, say, 1970. But they can't, since no-one bothered measuring CSOs in the 70's. The privatised industry fixed the raw sewage into the sea problem that they inherited from the nationalised industry. The privatised industry have replaced enough of the old leaking pipes that hose pipe bans are now rare and localised. This video shows that it is the privatised industry that is fixing the CSO problem that was again inherited from the nationalised industry. Governments have far too many other ways to bribe voters with other people's money, basic infrastructure gets to be neglected.
Never apologize for covering not-so-glamorous topics like this. Every now and then people need reminding, that there are awesome people in the world, dealing with the stuff that most people wouldn't.
Due to EPA mandate, Combined Sewer Overflow (CSO) projects are being implemented all over the USA for all sizes of cities. In Indiana, communities with CSOs were required to develop and implement what is referred to as a Long Term Control Plan, or LTCP. Control strategies that are aimed to significantly reduce or eliminate raw sewage discharge to the rivers and streams primarily include either reduction strategies (e.g. separating sanitary sewers from storm sewers, installing green infrastructure, etc) or storage/treatment strategies (e.g. inline or offline storage followed by wastewater treatment). The ecological, recreational and cultural benefits over the next 100 years are going to be quite impressive.
It's really not that surprising or difficult to handle - just need to keep it in mind when escavating and call specialists to disarm the explosives when needed.
This has been going on for decades, over a century. It is so normal that many countries, even in Europe, don't even bother to measure combined sewage overflows (CSOs).. The nationalised water industry pumped so much raw sewage straight out to sea that the UK was prosecuted by the EEC (as was). The only reason that people care so much is simply because the UK water industry is privatised. The nationalised water industry never bothered to replace the Victorian cast iron pipes, even as your bath water was restricted to 4 inches in 1976 & hose pipe bans were a regular feature of an English summer. The nationalised water industry didn't care about CSOs. It is the privatised industry that has fixed the raw sewage out to sea problem; it is the privatised industry that fixed leaking Victorian pipes, hose pipe bans are now rare & localised; it will be the privatised industry that will fix the CSO problem. Governments will never spend enough money to fix CSOs, there are far too many other ways to spend someone else's money to buy votes.

Portland OR did a smaller scale version of this and the results have been spectacular with the river now safe for swimming and recreation. This project will greatly benefit London for decades.
Mass immigration brought in 15 million people in 20 years so yeah, Britain does have a sewage problem. Those people didn't bring sewers with them. Or houses, or hospitals, or schools.
That was interesting to watch. That topic is so important to the life of a city and it's occupants. At least there is work going on to take care of it.
I worked on the Thames Tideway Tunnel helping to put the hand drawn diagrams of sections of the Thames wall into a computer system. It was for 1 week of work experience. The sections where next to all the vertical holes to be made as we needed to make sure the wall would not collapse and flood the project!
This was carefully investigated when the original sewers were designed. Bazalgette worked out the rate of flow that would enable the sewers to self clean. He also ensured that many quality checks were in place during the construction, and he insisted that inferior materials were removed from site. I believe that the quality of cement was the very first standard.
@@chrismoyler I was joking but that is a fascinating reply. I do somewhat pity the researchers that were tasked with calculating the viscosity experimentally.
@@jmchez- Compared to the newer toilets that use less water like with the half flush types the pipes now actually need a steeper grade due to less initial flow, this is also why there are more frequent backups and blockages in older systems as not all the feculent moves away with the shorter flush flows as they were originally designed for a higher volume of water to assist with the flow
@@matmul4850 "The Thames is considered to be the cleanest river in the world that flows through a major city. The Thames is home to 125 species of fish and more than 400 invertebrates." The brown colour is caused by sediment constantly stirred up because the Thames is a tidal river:- "Because the Thames is connected to the North Sea, each day it is affected by two low tides and two high tides. Thanks to this non-stop movement of the water, the sediment is continuously suspended in the water column giving it its trademark brown colour. This brown colour is the sign of well-mixed nutrients in the water which makes the tidal Thames a rich feeding ground for aquatic species including two species of seals and also porpoises."
It’s disgusting to think that raw sewage is being dumped in any river in 2024. The water firms need renationalising and then allowed to sort the problem out without having to pay billions to shareholders.

Great video as always, it makes me so angry our government has allowed our waterways to get into such a state in the first place! We need many more projects like this to save our waterways. Plus we need a massive upgrade in our water pipes the amount of water we loose to leaks yearly is astonishing.
The fact that sewage and water from downpour is mixed inside the Bazalgette sewer system makes it prone to overflow. The better solution for London would be to seriously consider, design and install separate systems for sewage and rainwater. That would allow for rainwater to just flow towards or into the Thames and would avoid the costs of an enormous sewage treatment plant, which is needed to filter all the mixed sewage this pipe will generate, before it is clear enough to be set on its way to the aquifer. Not to speak of the enormous costs of maintenance and continuous processing of sewage water which will take place in this treatment facility. Plus, what’s going to happen when there a years of lower levels of precipitation and this pipe and the consecutive treatment plant fall dry? Maintenance costs will still be absolutely necessary, drought will seriously impede the treatment processing and further increase the cost of treatment facility. It’s nothing but a bet on the wrong horse, as it is doubtful if this pipe will indeed create a sustainable solution for London’s problem of sewage overflow. There simply isn’t a pipe with a large enough diameter which can process the amount of water an atmospheric river can generate on the roofs and roads of London, which will mean the system will still be prone to overflow even when this pipe and its treatment plant are fully operational. Cheerio
Quite correct. First step is segregation of contaminated water from clean water. Storm water is not always clean, but it is cleaner than domestic sewage and should be kept separate. Segregating a combined system will be very disruptive and expensive, but is ultimately the right thing to do. In this case, what goes into the new sewer is overflow from the existing system. So should be diluted sewage assuming that overflow occurs only when storm water loads are very high.
The production quality of your videos is always stellar. I never thought I'd be glued to my screen for an explanation of the upgrade of the sewer system of London! I always love the animations, they help visualizing the projects and their details. But I also appreciate the views, camera angles, the editing, the presentation, everything! You always have a great project to present. Even this one lol
So much information to absorb and so many things felt like they were barely mentioned.

Excellent video and amazing insights into what's in London (we were on holiday there in Feb 2024). Amazing to see Esri being used this way too; I was an early product user, a long time ago. It's a software package that's come a long way.
A semi hidden mega project. Just imagine how many hidden ones there are. Germany during WW2 alone. Moscow's "2nd hidden" metro Fort Knox, Svalbard seed vault...
Very interesting. But one question it raised -- what happens to the "feculant" at the end of this tunnel, now 60 m underground? Is it somehow released into the channel? If so, before or after processing? How do you process sewage at such a depth? Would have loved to hear more about this.
I am in the energy construction industry and have worked on massive oil and gas projects like the greater Gorgon project where we had to preserve the wildlife on an island by sterilising massive cranes before shrink wrapping them before shipping to the island. Humans can really do almost anything if we try , that’s why I am so sad that we have been so slow at stopping Climate change. It’s always been the case that the will and the return on investment has always been the driver in most projects. Great channel.
Now if only they can do this for all the streams within the counties around the UK - ESPECIALLY the chalk streams in Buckinghamshire. Those chalk streams are very rare around the world and sewage dumping is having huge impacts on the wildlife found there. Not just that, but children and dogs cannot possibly go near them when they are contaminated by sewage which I used to do as a child and I'm in my late 20s! It's an awful problem across the UK at the moment and the entire infrastructure needs a massive overhaul.

The entire city stank of piss and shit last time I visited. So good luck with the project.
You lot in Londinium need to stop eating all that greasy meat & pie crust and start eating more roughage ie. Fruits & veg 😂
Great video as always, it makes me so angry our government has allowed our waterways to get into such a state in the first place! We need many more projects like this to save our waterways. Plus we need a massive upgrade in our water pipes the amount of water we loose to leaks yearly is astonishing.
I had no idea that much _ _ _ _ flowed into the Thames. Thanks for the warning not to swim in it.
Out of interest, how many years will it hypothetically take for the Thames to be noticeably cleaner?
Geez, massive, massive fan of your channel. But why in title talk about cost in dollards and not in pounds when it’s a UK project.
Likely, there are more American viewers than British
In sweden we solved the overflow problem with having separate systems for sewage and urban runoff.
We have that in U.K. too
The entire london is a sewer
I'm just guessing this system predates the complete separation of sanitary sewers from stormwaterrunoff? They don't mix at all in my area.
My friend I like to see One more Time ...thank you .
The fact that sewage and water from downpour is mixed inside the Bazalgette sewer system makes it prone to overflow. The better solution for London would be to seriously consider, design and install separate systems for sewage and rainwater. That would allow for rainwater to just flow towards or into the Thames and would avoid the costs of an enormous sewage treatment plant, which is needed to filter all the mixed sewage this pipe will generate, before it is clear enough to be set on its way to the aquifer. Not to speak of the enormous costs of maintenance and continuous processing of sewage water which will take place in this treatment facility. Plus, what’s going to happen when there a years of lower levels of precipitation and this pipe and the consecutive treatment plant fall dry? Maintenance costs will still be absolutely necessary, drought will seriously impede the treatment processing and further increase the cost of treatment facility. It’s nothing but a bet on the wrong horse, as it is doubtful if this pipe will indeed create a sustainable solution for London’s problem of sewage overflow. There simply isn’t a pipe with a large enough diameter which can process the amount of water an atmospheric river can generate on the roofs and roads of London, which will mean the system will still be prone to overflow even when this pipe and its treatment plant are fully operational. Cheerio
Quite correct. First step is segregation of contaminated water from clean water.
Storm water is not always clean, but it is cleaner than domestic sewage and should be kept separate.
Segregating a combined system will be very disruptive and expensive, but is ultimately the right thing to do.
In this case, what goes into the new sewer is overflow from the existing system. So should be diluted sewage assuming that overflow occurs only when storm water loads are very high.
So what happens to the sewage at the end of the New overflow?
It waits until it can be processed in sewage plant. 🤔
I must be missing something but why do they want to divert the River Fleet into the new sewer instead of letting it flow into the Thames?
Because what was originally the River Fleet is now a subterranean sewer.

Chicago did this in the 1980's called the Deep Tunnel Project.
Old colleagues from the the Greenwhich & Chambers Wharf shafts👍
And yet after one dump the thing is blocked
They built a system like this in Milwaukee back in the 70's. The Milwaukee Deep Tunnel System.
Well done for slipping in a cracking The Thick of It line.
The production quality of your videos is always stellar. I never thought I'd be glued to my screen for an explanation of the upgrade of the sewer system of London! I always love the animations, they help visualizing the projects and their details. But I also appreciate the views, camera angles, the editing, the presentation, everything! You always have a great project to present. Even this one lol
So much information to absorb and so many things felt like they were barely mentioned. This is NOT a negative, but a mention that I could easily sit through a good 30 mins of details on this masterworks. A request for longer episodes when the content is juicy? (maybe a poor use of words given the nature of this story ;)
Now we know why the Waterloo & City line is called "The Drain" :D
Excellent video and amazing insights into what's in London (we were on holiday there in Feb 2024). Amazing to see Esri being used this way too; I was an early product user, a long time ago. It's a software package that's come a long way.
A semi hidden mega project.
Just imagine how many hidden ones there are.
Germany during WW2 alone.
Moscow's "2nd hidden" metro
Fort Knox, Svalbard seed vault...
All money stolen from Indian's 🤣🤣🤣
UK sewage - Shaken not stirred!
Very interesting. But one question it raised -- what happens to the "feculant" at the end of this tunnel, now 60 m underground? Is it somehow released into the channel? If so, before or after processing? How do you process sewage at such a depth? Would have loved to hear more about this.
The Bowel Movement ONE!!
I am in the energy construction industry and have worked on massive oil and gas projects like the greater Gorgon project where we had to preserve the wildlife on an island by sterilising massive cranes before shrink wrapping them before shipping to the island. Humans can really do almost anything if we try , that’s why I am so sad that we have been so slow at stopping Climate change. It’s always been the case that the will and the return on investment has always been the driver in most projects. Great channel.
Now if only they can do this for all the streams within the counties around the UK - ESPECIALLY the chalk streams in Buckinghamshire. Those chalk streams are very rare around the world and sewage dumping is having huge impacts on the wildlife found there. Not just that, but children and dogs cannot possibly go near them when they are contaminated by sewage which I used to do as a child and I'm in my late 20s! It's an awful problem across the UK at the moment and the entire infrastructure needs a massive overhaul.
General public do not appreciate how much raw sewage flows into the Thames
Mail rail is a goddamn national treasure!
Finally, affordable living space
Smells better than northern London too

You clearly don't know what you are talking about
That engineer trying to justifiy his salary🤣🤣🤣. I literally built something similar (downgraded) when I was 15 for a GCSE project. Sewers are not a national problem, it's a local problem to the cities.
Does ESRI still charge significantly different prices for a license depending on where you are located? Last I checked an ArcGIS license in the US was roughly $3k, vs roughly $10k (after conversion) if you were in Australia. Ridiculous company.
The Chinese would have got this done and dusted in 6 months
Chinese infrastructure doesn’t last as long though?
Bazalgette was a genius.
Worst. Superhero. Ever.
An escooter and ebike tunnel system .....like the Tube.......could unify many North West cities and towns.
$5bn not small money...kenyan SGR took roughly $4bn...it shows how expensive it is to build under a city as old and as developed as London
