London , and exists in order that the Fleet CSO and the Low Level 1 sewers are diverted into the new super sewer .
New pipes , two interception chambers and a 55m-deep , 22m-wide shaft have all been fully constructed below the surface .
Now , architecture and landscaping works are progressing apace , with the installation of a green roof on site , new terrace and paving , more than 70 trees , core architectural elements , a range of permanent artworks , and more .
Granite and Yorkstone paving is also being installed at the site – which , once opened , will provide around an acre of all-new public space in the heart of London .
Work to remove a cofferdam at the western end of the site is set to begin soon , with the new public realm likely to be exposed to the River Thames later in the year .
Blackfriars will be one of the final sites on the Tideway project to be finished .
Adrian Telford , Tideway ’ s project manager for the site at Victoria Embankment in central London , said : “ We ’ re really proud to be finishing off the underground works for the super sewer and our sites along the route will now be able to capture flows and release the sewage into the tunnel , protecting the River Thames from this pollution . to open up the new areas of public space where you can get never-before-seen views of London and really embrace the riverside here in the city .”
Clare Donnelly , Tideway ’ s lead architect , said : “ The new areas of public spaces that have been created on the Tideway project are really starting to take shape and demonstrate the high-quality of spaces we ’ ll be leaving behind for London .
“ It ’ s around three acres of new land in total , all carefully designed to be both accessible and beautiful .”
The cost of the project is £ 4.5 billion , with the cost impact on water bills remains within the original estimated range of £ 20- 25 per year , set in 2015 .
Putney Embankment was the first new public space created by Tideway and was opened in September 2023 . While the initial completion date was set for 2024 , the COVID-19 pandemic has caused a slight delay , with commissioning now expected in early 2025 .
Nevertheless , the project is nearing its final stages , and Londoners can soon look forward to a cleaner and healthier River Thames , a testament to the city ’ s commitment to environmental sustainability and responsible infrastructure development .
“ Getting the first flows into the tunnel not only marks the start of a cleaner river , but also gets us even closer to being able
