London’s super sewer has been successfully connected to the existing network following a two-week programme of vital work from Tideway and Thames Water.

The use of the river for transport at Chambers Wharf, Tideway’s main drive site on the east section of London’s new super sewer, has avoided around 40,000 lorry journeys since tunnelling began.

A multidisciplinary team of experts have come together to undertake complex reinforced concrete works at Tideway’s Heathwall Pumping Station site.

Tideway, the company building London’s new super sewer, remains on track to deliver the project by 2025, following the most substantial review of the programme since 2018, according to its Interim Report and Financial Statements for the six months ended 30 September 2021 published this morning.

The 1000th ring has been installed on the Greenwich Connection Tunnel – part of the new super sewer for London - by Tideway’s Tunnel Boring Machine (TBM) Annie.

Ofwat has waived Tideway’s procurement obligations in respect of the development and piloting of an autonomous tunnel investigation system for use on the Thames Tideway Tunnel – the eighth Waiver Notice the regulator has issued to Tideway.

The final cost of London’s supersewer could be as much as £900 million above the original regulatory baseline of £3.4 billion, rising to £4.3 billion by completion in 2024 in the worst case scenario, according to the 2019-20 Annual Report published by Tideway, the company building the supersewer for Thames Water.

Credit ratings agency Moody's says that today's announcement by the Secretary of State for the Environment, Food and Rural Affairs that the Thames Tideway Tunnel project is being specified under the Water Industry(Specified Infrastructure Projects) (English Undertakers) Regulations 2013 is a key step towards implementation of the project.

All main works construction procurement packages for the Thames Tideway Tunnel have now been released with the invitation to tender sent out for the third and final section yesterday.

Thames Water has published details about the potential procurement, designation and licensing of the infrastructure provider which will be needed for the construction of the Thames Tideway Tunnel Project – with an estimated value of £4.2 billion.
