Tideway has published its report confirming the super sewer is on time to be delivered by 2024, preventing millions of tonnes of sewage polluting the River Thames
Chairman Sir Neville Simms, said: “Building the super sewer for London is a huge responsibility and one that we are proud to have. I am very pleased with the progress our team has made this year – from the health, safety and wellbeing of our people, to the construction of the tunnel itself.
“We have made this progress whilst always considering our impact on London’s environment and its communities. We look forward to making significant headway underground in the year ahead.”
Three kilometres of the tunnel, which will prevent millions of tonnes of sewage polluting the Thames, have now been constructed and four giant tunnelling machines are digging deep below the capital.
Earlier this year Tideway announced that it had increased its super sewer cost estimate by eight per cent. This included substantial investment in the company’s river transport plans as well as taking account of unforeseen engineering challenges. Tideway confirmed that there will be no change to the estimated £20-25 annual cost range for Thames Water bill-payers.
Within its annual report Tideway has revealed details of its innovative river transport plan which aims to reduce the project’s carbon footprint as well as reducing road safety risks and taking the pressure off London’s road network.
It is taking around 200 lorry journeys off the road each day by using the river to transport material. More than one million tonnes of material have now been transported by river, saving more than 115,000 HGV movements.
Trials undertaken by Tideway have shown using the river can produce significantly fewer emissions, with a 1,000-tonne barge producing an average of 90% less carbon dioxide than a standard HGV equivalent.
Andy Mitchell, Tideway CEO, added: “With work on the tunnel in full swing, and a continued focus on keeping people safe, our operations this summer will see a major increase in our river traffic.
“By transporting at least 90% of our tunnelling material by river instead of on the road, we are reducing our carbon footprint, as well as reducing road safety risks in London – two key issues for the capital. We are confident our work will lead the way in how businesses in future consider sustainable options for transporting goods and materials.
“While our ultimate goal is to clean up the River Thames, we’re also committed to boosting the river economy, increasing jobs and improving safety standards.”
Tideway’s annual report also reveals the company is delivering on its wider legacy commitments for London and the construction industry.
To date, more than 100 apprentices have taken up positions on the Thames Tideway Tunnel project. A cohort of 12 tunnelling apprentices have started working across the project, in the first tunnelling apprenticeship of its kind in the industry.
Through a partnership with the Construction Youth Trust, Tideway has also worked with around 7,000 young people in London schools to highlight the range of careers available in construction.
