Sixense awarded ‘London Super Sewer’ contract

Sixense’s Acoustic division has been appointed as Noise, Vibration and Air Quality specialist to provide comprehensive consultancy and monitoring services for the six main worksites of Thames Tideway Tunnel’s East section. Sixense are extremely proud to be a part of this prestigious project.


This contract is one more step towards the achievement of our growth strategy launched 6 years ago, with the creation of our acoustic division in London, with the support of Sixense Environment in France.


The Tideway East contract involves construction of two sections of tunnel and five large shafts which intercept the existing overflows of untreated sewage that currently enters the River Thames.


In total, the £4.2 billion project has 25 km of tunnel through central London and requires 24 worksites.
