wwtonline.co.uk | FEBRUARY 2019 WET NEWS 17 Project Tracker: Thames Tideway Tunnel Project: Thames Tideway Tunnel Client: Bazalgette Tunnel Ltd (on behalf of Thames Water) was set up to finance, build, maintain and operate the tunnel Completion date: 2024 Value: £4.2bn Purpose: Transfer sewage waste away from the River Thames, reducing the number of spills from combined sewer overflows (CSOs) and improving environmental water quality in the river. Details: The new 25km tunnel will lead from Acton in the west of London to Abbey Mills in the east, where it will link up with the Lee Tunnel and convey the sewage to Beckton Sewage Treatment Works. The tunnel will use gravity to transfer waste eastwards and will lie at depths of between 30 and 60 metres. Tunnel Boring machines will enter and exit the ground from three main drive sites: (Carnworth Road (Hammersmith & Fulham), Kirtling Street (Battersea) and Chambers Wharf (Southwark) and the tunnel construction is accord- ingly split into three sections: West, Central and East. Key contractors: BAM Nuttall, Mor- gan Sindall, Balfour Beatty (west section); Ferrovial Agroman, Laing O'Rourke (central section); Cos- tain, Vinci Construction Grand Projets, Bachy Soletanche (east section). Project milestones: Main works and financing contracts awarded in 2015; main works preliminary con- struction began in 2016; the first two TBMs were lowered into the ground in July 2018 and tunnelling began in November What they say: "The Thames Tide- way Tunnel is the largest project in the UK water industry for 150 years, and it will probably be the largest for the next 150 years as well," Phil Stride, Tideway strate- gic projects director, said in November 2016. "It's been a pleas- ure and a privilege to be involved in what is from a water industry perspective an incredibly high profile project. It's also very out- ward-focusing. Across London we've dealt with 14 London bor- oughs, and there is a stakeholder map of the project showing all the stakeholders the project's got, which needs a decent-sized wall to put up. That calls for a different set of skills than you normally need on a water industry project and there is a huge external dimension in terms of hundreds of public meetings, external brief- ings and the like, and a lot of e n g a g e m e n t w i t h l o c a l communities." • The 25km tunnel is designed to capture the tens of millions of tonnes of pollution that currently enter the River Thames every year WATER INDUSTRY ASSET MANAGEMENT CONFERENCE 2 MAY 2019 | BIRMINGHAM @WWTLive and use #WaterAsset to tweet about the event FOLLOW US REGISTER NOW Access the insights you need to tackle PR19 and AMP7 head-on, visit: wwt.events/asset THE UK'S PREMIER CONFERENCE FOR SENIOR ASSET PROFESSIONALS SERVING THE WATER INDUSTRY Eliane Algaard Director of water Northumbrian Water Jason Tucker Director of strategic delivery & commercial assurance Anglian Water Nevil Muncaster Director asset management Yorkshire Water EXPERT SPEAKERS INCLUDE WWT-WIAM19-A4ad.indd 1 14/01/2019 13:00
