PROJECT DESCRIPTION

A project to rehabilitate the 170-year-old Bazelgette sewer without the need for rail or road closures. The project boasts impressive savings of £23m and 26,443 tCo2 against the client’s original business plan. With a design life of 120 years, it eliminated catastrophic failure of the asset and associated disruptions and risk to the public.

Judge's comment:

The clever engineering solution developed for this project strengthened the sewer from the inside, meaning minimal disruption to the public with no impact on the busy London roads above or underground railway below. 

As the sewer was operational throughout the project, cutting edge monitoring and alarm systems were used to ensure safety.  This data allowed the design team to accurately assess interfacing structures and manage space limitations.
 
The solution has delivered an asset that is now capable of maintaining wastewater operation for a further 120 years with very little public knowledge of its existence. The possibility of catastrophic failure of the asset has been abated for many years to come.
