In 2014, 62 million tonnes of raw sewage polluted the tidal River Thames in London. In fact, we’re still relying on the engineering brilliance of Sir Jospeh Bazalgette and his sewers from 150 years ago. To upgrade this Victorian sewerage network and stop it overspilling into the river, over £4.2bn is being invested in a new state of the art sewer tunnel that spans 25km beneath the city of London.

‘Imagineering and engineering’ perfectly embodies the duality of this epic new build – On the one hand, the sewer is a huge engineering feat with fantastic practical and ecological benefits. And on the other, it opens up a world of limitless possibilities that emotionally reconnect Londoners with their river. Our brand marque reflects both the engineering story beneath the surface, and equally the potential of what can happen above it.

The tunnel is not due to be completed until 2023, so we’ve got a bit of a wait to see what impact it has on London. However, the completion of the new Blackfriars Pier – so that Londoners can continue to use river transport throughout the main works – is the first visible clue that change is set to happen.
