Thames Tideway Tunnels Project


Thames Tideway Tunnels Project

The Thames Tideway scheme – coupling improvements to London’s three main wastewater treatment plants (WWTPs) with the construction of a storage-and-transfer tunnel nearly 35km long – forms one of the city’s most ambitious wastewater projects since its first sanitation system in the mid-19th century.


With an eight-year estimated construction schedule, the tunnel is intended to improve the capacity of London’s sewerage system and help prevent sewage discharge into the River Thames


Key players involved with London's WWTPs are:


Thames Water which owns and operates the plants, being a member of the TTSS, along with Defra, the EA, GLA and Ofwat. Jacobs Babtie were responsible for the review of the TTSS recommendations on behalf of Ofwat.
