About the organisation

Tideway is the organisation delivering the Thames Tideway Tunnel, on behalf of its owners at Bazalgette Tunnel Ltd. Tideway employs more than 400 highly experienced professionals to deliver the 25 kilometre sewer tunnel needed to prevent an average 20 million tonnes each year of untreated sewage discharging into the tidal River Thames in London.

Tideway is independent of Thames Water, and its revenues are determined via a separate licence for Bazalgette Tunnel Ltd, from Ofwat. Bill payments for the tunnel will be collected via Thames Water. Thames Water will continue to provide water and wastewater services to its customers as it does now.

Project legacy

The tunnel will not only improve the environment, ecology, public health, appearance and reputation of London, but it will also give a much-needed and immediate boost to the economy by offering thousands of skilled jobs and hundreds of apprenticeships.
