The BMB JV (Bam Nuttall/Morgan Sindall/Balfour Beatty) has taken delivery of a huge stainless steel vortex system at the site of the Thames Tideway pumping station in Hammersmith, London.
The steel vortex system and a single piece of pipe large enough to house an entire Tube train carriage, will help to handle around two million tonnes of sewage overflows that currently run into the Thames from the station annually.
Tideway will divert the flows into a new 25km super sewer under construction below the river. At Hammersmith, the flows will need to drop down a 15m shaft. Falling that distance, the flows would wear away the bottom of the shaft but the 28t vortex generator will ‘spin’ the flows down the pipe, removing the energy and preserving the base.
