Covid-19 adds nine months and £233m to Tideway

26 August 2020

In an operational update to investors, Bazalgette Finance has revealed that construction work on Tideway will likely be completed in the first half of 2025 – nine months later than planned.

The revised handover date is attributed to the impact of the Covid-19 pandemic on Tideway’s operations.
The delay is also said to add a further £233m to the forecasted project cost which now stands at an estimated £4.133bn.

In its statement, Bazalgette Finance said: “Tideway is in discussions with Ofwat on a package of measures that would mitigate the financial impact of Covid-19 on the company. We are making progress in these discussions and we expect to reach a full agreement in the coming months.”

Other than ongoing essential works, construction on Tideway paused for a short period during the coronavirus lockdown. It recommenced at the majority of the company’s worksites in May, but at a slower pace due to the effect of social distancing compliance.

Dubbed London’s ‘super-sewer’, Tideway is currently the biggest water infrastructure project in Europe and is designed to prevent millions of tonnes of raw sewage entering the River Thames every year.
