The hydraulic supply was firstly installed around the (older) docks,
where it was used to operate bridges, cranes, capstans, lock gates
and so on. It was also used in railway goods depots in the area to
operate lifts, cranes, capstans and so on. Obviously these docks are
fairly close to the City. As well as the accumulators there were the
It was then extended much further, covering much of what we would
now call central London, it was used to operate lifts in hotels as
well as other machinery.
has a short history.
The tunnels run through the older docks, which were being converted
to memorials to the Mad Woman of Finchley at the time, so they were
ideal for conversion. Some culverted rivers, combined sewers and
storm water pipes were also used for fibre cabling.

How about this. A hydraulic tower at Birkenhead Docks.
It provided power for the huge ship lock gates, and other lifting gear. It
was also used as a buffer for pumping evening out pressure and flow. Water
from the river at the lowest high tide would be pumped into the docks to
make them deeper for deep draught vessels.
The massive Liverpool docks was filled with these towers. As in London the
pipes ran under the streets to warehouse and whatever. They lifted and
turned things before electric motors came along. When the pipes burst under
the street a great fountain of water would come up.

was for the steam boilers.

I did! The London Hydraulic Power Company...but my understanding was
that part of it was still in (hydraulic) use until a few decades ago.
And the first Brunel foot tunnel (just west of Tower Bridge, with the
small domed entrances) is now used for fibre etc.

Basically build a 1000ft wall round london, and fill it up.
Not a bad idea, but expensive.
