Latest update of works on London's super sewer

Tideway has reached a few exciting milestones in the last few weeks. Take a look at what progress we made in February in our latest timelapse video.

Some key milestones in the last month included the arrival of two more tunnel boring machines, Millicent and Ursula, to our Kirtling Street site near the Battersea Power Station, and at Greenwich, diaphragm walling for our shaft is underway which is an essential part of digging a tunnel shaft.

The Thames Tideway Tunnel is a 25km super sewer tunnel being constructed to tackle the problem of sewage pollution in the River Thames. Once completed it will tackle the problem of millions of tonnes of untreated sewage that flow into the Thames each year.

Work on the super sewer ramps up in 2018 with tunnelling starting later this year.
