Back in 1962 I worked on the Northen Outfall Sewer at West Ham just East of Abbey Mills pumping station, where the five outfalls cross several railway tracks and Manor Road West Ham. The sewers were damaged in WWII and repaired with cast iron tunnel segments, though great for a quick repair, the webs and bolts on the inside caused blockages with the solids and other waste catching on them. The pipes were flushed with water from Abbey Mills and then each pipe in turn was closed off and pad locked. Then the tunnel segments dismantled and new bridge girders and hanging brackets installed. New cast iron segments installed with webs and bolts on the outside, the recessed joint grooves filled with steel filings. Then the pipe was commissioned, and the operation carried out four more times. This was carried out through a terrible winter with thick fogs that on one occasion it took my father and I nine hours to travel home to Barnet North London. London was covered in ice, men were taken of the dole and set to ice chipping walkways etc. To lift the concrete beams into place over the railway tracks, a rail mounted steam crane was hired from British Rail, it was amazing to watch. The driver received signals from the banksman blowing a whistle for stop, the direction signal given by hand, the crane driver would carry out the lift for example, then the banksman would blow his whistle for stop and all the crew would shout stop. This continues for each raise, lower or swing in turn.

I worked on this project, many years ago. Used to manage a bunch of small ships, which were used to move million tons of soil excavated during tunneling operations, out of London. With the help of this excavated material a brand new saltmarsh was created at Wallasea Island. What used to be agricultural land, these days is a wetland for all kinds of wildlife.

The ground underneath London is like Swiss cheese. As well as the old sewers there is the Underground Railway, the Mail Train, the London Ring (A large bore tunnel that is an deep level drinking water reservoir.), a service tunnel distributing high voltage electricity around London, and numerous bunkers built during WWII and in the post WWII era known as the Cold War.

One good way to reduce solids loading in the sanitary sewerage system would be to introduce source separation; for example, solids such as fecal matter will be filtered through a thick layer of combustible garbage which will be periodically removed withma screw auger ( which will also remove excess moisture). The solids could either be converted into various liquid and gaseous fuels, or even, if possible, burned directly. The heat could then be utilized for triple-effect distillation.

Will it separate run off water from sewage water? That's the main issue at the moment, as the combination of both causes the overflows into rivers/ocean. Run off water is fine to release, sewage is certainly NOT.

@suburbia2050 6 ай бұрын

It's mainly the increasing frequency of heavy rain falls and flash floods that is causing the issue (Londons population has only just recently gone beyond its peak population of 1938 although clean water usage has increased per person to be fair), that is causing the dramatic increase in frequency of overflow into the Thames, this "super sewer" is basically built to capture the existing overflow and send it to the sewage works East, instead of into the Thames, the existing sewer system is still going to be there and working as before. There will still be overflows from this Super Sewer into the Thames during unusual heavy storms but it will be a far fewer occurance than today.

Have any idea how difficult that would be? To separate rainwater from sewage would in many case be near impossible and would require huge amounts of roadworks and disruption to almost every household, many homes in central London have just one drain that handles both waste water sewage and rainwater. When the system was first built rainwater was meant to help flush the sewers through.

There's a small mistake with "Banchy Soletanche". It is "Bachy Soletanche UK", without a "n" in Bachy. It is the UK subsidiary of Soletanche Bachy", a huge French construction company / group currently involved, like VINCI, in the building of the Grand Paris Express, among many other projects. It is currently the world's largest geotechnical construction company. The UK subsidiary was founded by Bachy in the mid 80's, before the merger of Bachy with Soletanche, that's why the name is reserved in the UK, while it is Soletanche Bachy in France and worldwide. Bachy UK was established by the acquisition of Pigott Foundations Ltd and Foundation Engineering Ltd. And it's VINCI Grands Projets (not projects), as it is the French name Grands Projets meaning Great Projects. The video is great and very interesting but it could have mentioned that the super sewer tunnel seems to run under the Thames for a substantial part of its length, following the meandering path of the river.

@Dionysos640 2 ай бұрын

Soletanche Bachy itself is part of the Vinci group of companies. An amusing fact is that the French pronounce Vinci "Van-si" whereas in the UK it is pronounced the italian way, "Vinchy" which is solely because of people being familiar with this pronunciation through Leonardo da Vinci.

@KyrilPG 2 ай бұрын

@Dionysos640 It's also the reason for Frenchies to pronounce Vinci with a nasal i. Since Da Vinci settled in France with king François the 1st, his name has been Frenchified as "Léonard de Vinci" and pronounced like a French name.

My point still stands as whilst the upfront costs will be met by many funders, (not UK taxpayers) the long term pay off will be footed by an added levy on the bills of thames water customers.

@@kaneworsnop1007 I do not know the relative rates for different areas of the UK re: water rates. And I can't speculate on what the future holds regarding how this project will be paid for, but the current financial model is that the cost will be covered by an amount being added to the water rates of Thames Water customer. As far as I am aware nothing has changed about that since the planning process and funding was agreed. I would expect most bill payers will never be aware of either the project or the added cost. And I can't imagine a scenario where the is enough of a voice from the public to change the funding and payment model. After lots of speculation about extra annual costs of up to £80 a year, OFWAT confirmed the extra cost to pay for this project will not be more the £25.

Separating the rain water would be a relatively easy fix to prevent dumping raw sewerage in most areas, during heavy rain fall instead of going through the treatment plant it could go out through overflows, not ideal, but a lot less harmful than raw sewerage. No one wants to spend the money to put all the new sewerage pipes in though.

The same companies, Bachy Soletanche UK, Costain and VINCI Grands Projets, are building (if it isn't delivered already) the Shieldhall Tunnel in Glasgow, as a major upgrade to the city's wastewater network. 4 days a year (certainly more in the coming years), combined with the very large population of London, are enough to massively pollute the Thames and its estuary. That 4 days too much, it should be zero. Every single drop of wastewater should be treated to avoid environmental harm. Especially when it also carries wet wipes, tampons, drug residue, cleaning products residue, mineral oils, etc. Crap in itself is enough yo pollute, but with everything else a large city produces, it's a biological and chemical hazard.
