Why do we need the Thames Tideway Tunnel?

Why we need the Thames Tideway Tunnel The tunnel will intercept at least 94% of the millions of tonnes of sewage overflowing into the tidal Thames every year from the capital’s overloaded Victorian sewer system. It will also capture all of the ‘first flush’ from the sewers after heavy rain.

Is the London super sewer complete?

Tunnelling on the western section of the project was completed in September 2020.

Does sewage go into the Thames?

London’s overloaded sewage system routinely discharges raw sewage into the Thames, on average once a week. The city’s combined sewer overflow (CSO) system was designed to be a safety valve for occasional use, to prevent sewage backing up into people’s homes when the sewage system is overloaded.

How much is sewer in the Thames?

Do people live in the tunnels under London?

Homeless people forced to live in dark, squalid tunnels underneath city’s streets. The vast majority of thousands of pedestrians walking across the carriageway every day will have no idea of the the harsh and squalid conditions endured by those living underneath. They are the city’s hidden homeless.

What is Thames Tideway Tunnel and how long is it?

At 25-kilometers long and 65-meters below ground, Thames Tideway Tunnel is the largest water infrastructure project ever undertaken in the U.K.

What is the best route for the Thames Tunnel?

Abbey Mills Route – this route would connect the Thames Tunnel to the head of the Stratford to East Ham part at Abbey Mills Pumping Station. This would follow the same route but deviate north-east to Abbey Mills. The main tunnel length would be about 9 km (5.6 mi) less than the River Thames Route and save about £900 million.

How will London’s new sewer system affect the River Thames?

It will modernize London’s 150-year-old sewer system, originally built for a population less than half its current size, reducing untreated discharges into the River Thames by tens of millions of tons per year.

How did we help the Tideway Tunnel team?

We helped the Tideway Tunnel team to protect the river environment during the construction and for the design life of the tunnel. We also trained their fleet of vessel masters at our UK Ship Simulation Centre to ensure that they met Tideway’s health and safety standards.
