The Secret $5BN Tunnel Under London 

Great Video! A Video about the "Emscher-Umbau" in Germany wuld be great, it was completet last year and with 5.5 Billion Euros the biggest environmental project in Europe. A whole river system was cleaned from raw sewage by building massive underground tunnels and new WWTPs!

Keep up the good work Your videos are amazing

Pneumatic mail railway? Do a vid about that!

I seriously LOVE that u have a mates in co structure sticker on your hard hat.. it's a serious cause that need more support.. nice work guys 👌

i want ride a skateboard west to east to see how fast i could get

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.

Joseph Bazalgette pumped sewage away from people's homes while his great-great-grandson, the TV producer Peter Bazalgette, ...

Absolutely great work from him

@@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.

They also didn’t waste time on the TikTok 😅 We need those programs, otherwise, nothing will be done bc of distractions. Also, projects are bigger, there is more law restrictions, and variables to account for, like already built bridges, subway, etc

Unlike the governmentsvresponse to the original M25 planning.mits too big they screamed, so now what happens, we have to put up with building the extra lanes that should have been done originally.

Very easy to wiggle into feculent Conservative politics though, especially if His Feculency returns.

@@ahavelandas opposed to the CURRENT senile and low exhaulted “feculence” 😂

yeah, or "untoward" used by that fellow. I don't hear or read that everyday.

He used an adjective where there needed to be a noun, that's nothing to celebrate.

@@igrim4777 True-“feculent” _is_ an adjective. If you hadn’t pointed it out, I might not have known. (That said, given that a word ending in “-ent” with a somewhat-related meaning, “effluent,” _is_ a noun, it seems, to me, an understandable error.)

It's more an example of poor planning and poor policy choices

I’d say general water management. Considering we’re starting to see the outcome of all the private ownership

@@dylanpyle6500In terms of future planning, general governance London is far and away the best place in the UK.

@@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.

@@gareth4592 that does not mean much from a nation and world that refuses to see the issues at hand

Thank you so much!!

@@TheB1M yes 🙌🏻 I agree ☝🏻 .

So good to see the B1M grow into the channel it has. Such a good channel

@@TheB1Mi sit down to eat and you’re discussing excrement… mate. Please.

Have that Logan Paul

Thames river is already clean for a urban river, this will make it cleaner than ever.

Thames is actually surprisingly clean already, the brown is from sediment.

In Paris they work very hard to clean up the Seine. They want it clean enough to hold the swim contests in the olympics there in a few years.

@@noahwail2444 The Olympics is this year,

@@noahwail2444you mean in a few months lol

After 2 world wars it's not an uncommon problem in many parts of Europe.

It just a standard hazard in Europe.

just like spiders in Australia

things got pretty spicy here in the EU, thats why we're pretty chill now.

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.

Later in 2024 is the plan

@@TheB1M Thanks for reply! 👍

I work on this project. It doesn't finish until at least 2026

Had, it long since close down but you can visit it and ride on the trains.

And you can ride on it! The Postal Museum.

@@Chevy-jordan One of the many things I have never gotten around to doing in London. No one can never say there isn't anything to do in London!

We have that in U.K. too

The Thames is already substantially more clean than most city rivers Paris was horrendous before the started caring about it because of the olympics

​@Alucard-gt1zf No its not. The Thames is no cleaner than any other river running through other European countries.

@@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."

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.

Many toilet manufacturers test the flushing power of their product using wadded toilet paper and sausages. I am not kidding.

@@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

Nah they will get a multi million pound bonus

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.

You would need to replace the entire sewage system back to the individual street and property - for a major city like London virtually impossible except over hundreds of years. This is the problem with CSO. So this is a clever solution for the problem - collect the overflow and make sure it ends up at the sewage treatment plant. Which is presumably getting a massive upgrade to deal with the additonal volume - I believe the normal flows already end up at Becton.

pumped up to ground level and treated at Becton sewage treatment works, then discharged into the river once clean enough

@@raymears111 Thanks. Not completely unlike what my Zagreb does (on a _very_ different scale, of course.)

I think that it is about controlling the speed of the water. 🤔
