    London Bridge Sewer

    It was the back end of summer and we decided to take a look in London Bridge Sewer

    Siologen had always recommended this place, so one evening with adders I did just that

    The two significant explored bits of this system are known as st00ps limit, and Last Bastion

    It was a steamy, turdy affair and difficult to traverse at times, however it didn't disappoint :thumb


    Having looked at the main drainage map I managed to locate a lid upstream in the Moorgate area

    It was far from discreet night or day, but the best of a bad bunch

    So, without hesitation we descended into the bowels of London once again

    We dropped into barely a 5ft egg

    [​IMG]


    I decided it was a good idea to head upstream where it shrinks to 4ft;
    Here a junction where 3 local sewers converge

    [​IMG]


    Siologen did once warn me that anything beyond London Wall was stoopy

    LBS has many connections and this just being one of them on the Western branch

    We decided to head downstream in search of the LBS main line, via this slippery 5ft egg

    [​IMG]


    Eventually we plopped out of the side pipe (below left) and into the LBS mainline at this junction

    [​IMG]


    Not the best of pics, but look up and this chamber incorporates a huge domed ceiling

    As for it's purpose I'm not sure, however it's pretty impressive all the same

    [​IMG]


    Plan A, was to head upstream

    We followed the fresh towards Finsbury Circus through a sizeable 10ft egg

    There is some major cross rail works going on here at the minute

    The upstream line (right) is filled with all sorts of monitoring gubbins

    [​IMG]


    The incoming sewer on the left, is the Goswell Street Sewer, it heads through Barbican and up towards Pentonville

    Back in the mainline heading upstream of cross rail towards Shoreditch it eventually shrinks to below 5ft

    It was at this point "anything beyond London Wall is a stoop" reminded me we needed to point ourselves South


    At a later date I shot up a crane in the area to see what was going on above ground

    [​IMG]


    Back to where we emerged below Moorgate, we headed downstream

    Luxury as it's back to a 10ft egg

    It proved difficult grabbing pics as the lens kept misting up worse than any other system I'd been in

    [​IMG]


    I wouldn't advise going in here when it rains

    There is little in the way of escape, the few lids that exist are all in the middle of busy roads

    [​IMG]


    Continuing downstream towards the Bank of England a number of side pipes join and the sewer is lined with fibre

    [​IMG]

    [​IMG]


    London Bridge Sewer is quite unique as it's been vastly altered over the years;

    With other sewers having been diverted and newer additions along the route added

    The construction methods and choice of masonry constantly changing throughout

    [​IMG]

    [​IMG]


    ^ In the above example the larger egg comes to an end

    Here a large domed shaft to a breather amongst the hustle & bustle of King William Street above

    Ahead, the sewer continues via a 6ft brick arch

    You can see the multicoloured brickwork as it's been bodged together over the centuries

    It started to get deeper just beyond the 2 local sewers that have also been added

    These drop in from a higher level around 8ft either side of the shaft

    I climbed up to see what all the fuss was about

    [​IMG]

    Sorry the pics are a bit rubbish,
    my lens was steamed up and the focus mechanism was failing as well as being sprayed with a fine mist of p00p


    As you can see, the 6ft brick arch snakes around Bank tube station

    [​IMG]


    Turning around, and heading downstream construction changes to a 5ft RCP

    it's here, the sewer runs underneath the vaults of the Bank of England

    A short distance down, the flow disappears down into the Low Level No.2 Interceptor, in the only crap pic I have

    [​IMG]


    Beyond the oak chase boards, from the interceptor weir, the RCP continues

    In order to traverse downstream, one has to pass through this fetid pit of arse porridge & H2s :thumb

    [​IMG]


    Once past the porridge and the Bank of England, it's a dry stoopy RCP as it heads towards Monument

    The RCP was no doubt there to replace the crumbling brick work below the vaults

    [​IMG]

    [​IMG]


    It's business as usual with the return of a a 12ft brick barrel as local sewers begin to dump their loads thereafter

    [​IMG]


    Within 10m it's another shape change, this time an 8ft RBP

    Further down, and deep below King William Street is this split,
    where West/East branches of the London Bridge Sewer converge

    [​IMG]


    We left the stretch down to the Thames for the time being and headed up the Eastern branch which also incorporates the Shoreditch sewer

    This stretch of "London Bridge Sewer" also has connections with the Nightingale & Irongate sewers

    These serve the area around Aldgate and is eventually intercepted by the Low Level No.1 & No.2 sewers both in close proximity to Monument tube station and London Bridge itself

    Here a large drop shaft,
    which I assume was used during construction and since serves as a manhole access close to Fenchurch Street

    [​IMG]


    The pipe diameter soon increases to a sizeable brick oval approx 12ft

    [​IMG]


    A short distance, a junction where the sewer splits at Bishopsgate

    It's essentially the Shoreditch Sewer which heads up the A10 towards Shoreditch High Street and onto Haggerston

    You may wonder why the flow of fresh is lacking here..

    This is because it's intercepted by the Low Level No.2 a bit further up the 5ft stooper on the left split

    [​IMG]


    We continued up the right hand side of the 'split' a short distance before we reached a tumbling bay

    [​IMG]

    Up top, barely a slippery 5ft brick egg which appeared to go on for ever and a day

    There was minimal flow and the occasional intermittent discharge from some side pipe further upstream

    Clearly we weren't traversing up the A10 in this, ridiculous!

    [​IMG]


    Enough stooping through shit, it's no fun honest :p

    We quickly headed back to the luxury of said 12ft brick oval on the downstream stretch towards father Thames

    [​IMG]


    Flow is fairly minimal after the upstream interception, with only the odd side pipe contributing

    And also owing to the fact it hadn't rained for a couple of weeks

    [​IMG]


    As we head down to London Bridge, a couple of side branches connect

    [​IMG]


    It wasn't long before we reached the downstream limit just before London Bridge

    Here, a large chamber which is home to 2 local sewers and a flap,
    to what is assumed a further tidal outfall chamber beyond before it outfalls to the Thames

    [​IMG]


    A ladder leads to a gallery above for inspection purposes and a manhole to the surface

    [​IMG]


    What ever remains of the flow after the last interceptor (which is minimal) in dry conditions,
    disappears under the gantry and off into the Low Level No.1 beyond

    Funny how some sections are almost dry.

    I'm also always surprised at how vulnerable the fibre backbones are.

    The photos are excellent and the time you've taken to write the descriptions really helps explain what we're seeing. Superb report.

    Hi, I'm new to this forum and I wanted to say what a great report and the photos are so cool, I wish I had the guts to do something like this.
