“While it is no longer used for hydraulic tubes, the tunnel still carries water mains. The hydraulic tubes, once a major source of power in the centre of London, have since been replaced by telecommunication cables. A small round entrance building survives at Tower Hill near the Tower of London's ticket office, a short distance to the west of the main entrance to the Tower. This is not the original entrance, but was built in 1926 by the London Hydraulic Power Company, with a ring of lettering giving the original date of construction and naming the LHPC. The entrance on the south bank of the Thames was demolished in the 1990s, and a new one has been built in its place. It is located just behind the Unicorn Theatre on Tooley Street, but there is no plaque to mark the site.” (Tower Subway, Wikipedia)
