the major Thames Tunnel project

 

London’s Victorian sewerage system urgently requires more capacity to meet the needs of modern-day London. The existing sewerage network is 150 years old and is now too small to transfer all London’s sewage to the treatment works for processing. As little as 2mm of rainfall can trigger a discharge into the River Thames. 39 million tonnes of untreated sewage flushes into the Thames in a typical year. That’s enough to fill the Royal Albert Hall 450 times!

 

The Thames Tunnel is proposed as a solution to this growing problem. The project is currently in a planning and consultation phase before receiving the final go ahead to progress. The proposed tunnel is to be 7.2 metres in diameter, approximately the width of three London buses. The tunnel will be about 67 metres deep, the equivalent to a 20 storey building underground. The preferred route is approximately 25 kilometres (15.5 miles) long under Central London – making it one of the largest and deepest tunnels under the city. The plan is for 6-7 years of construction work proposed to begin in 2016.

 

“The data quality and consistency of risk management information is absolutely key…We do 50-60 risk reviews every month. If we’d have used spreadsheets for risk management then we would have had 7,500 by the end of the project.”
