Detailed plans for the construction of London’s proposed ‘Supersewer’, developed by Thames Water, will be delivered to the Planning Inspectorate on 28 February 2013.
The company has today confirmed that is the date it will submit its 50,000 page Development Consent application for the project, urgently required to help tackle discharges of untreated sewage to the tidal River Thames.
Within 28 days the Inspectorate will decide whether the application is a valid one, including for example whether the consultation undertaken was adequate.
If accepted, all the application documents will appear in their own section of the Planning Inspectorate’s National Infrastructure website. Thames Water will also make them available for scrutiny at six public locations, to be announced next month, along the tunnel’s proposed route, three either side of the river.
Phil Stride, Head of Thames Tideway Tunnel at Thames Water, said:
“Following a thorough process of public consultation, which started back in September 2010, we have now finalised a highly detailed document, explaining how the project’s delivery will be managed.
“It’s the result of many months of work by the team to ensure the application addresses all the relevant legal and technical issues.”
If the Inspectorate accepts the application is a valid one, it will appoint an Examining Authority of up to five inspectors to consider any matters arising. As part of this process, interested parties will be able to make representations.
A Preliminary Meeting, open to those who have registered an interest, is expected to take place in early September 2013. Chaired by the Inspectorate, this will determine how the examination will be carried out. This will include consideration of more detailed hearings on site specific matters, as well as project-wide issues.
Once the Planning Inspectorate has concluded its examination of the application, a recommendation on whether or not to grant approval (by issuing a Development Consent Order) will be submitted to Government ministers to make the final decision. This is expected in Autumn 2014.
If consent is granted, preparatory construction work on the project is scheduled to start in 2015, with main tunnelling due to begin in 2016. The target completion date is 2023.
The Thames Tideway Tunnel proposals require a number of construction sites, from Acton in the west to Abbey Mills Pumping Station in Stratford in the east. There the 15-mile tunnel, the deepest and longest ever constructed in the capital, would join up with the Lee Tunnel, already under construction.
Along with separate work also under way to expand the capacity of the five sewage treatment works on the tidal River Thames, the tunnels’ purpose is to tackle the 39 million tonnes of untreated sewage that currently overflows into tidal stretches of the river in a typical year, when the capital’s Victorian sewerage network fills to capacity, sometimes after just 2mm of rainfall.
The tunnels will convey the excess sewage for processing to stringent standards at Beckton Sewage Treatment Works, with green energy being generated from the resulting sludge, before the treated water is returned to the River Thames.
All three schemes are needed to ensure the UK meets the requirements of the EU Urban Waste Water Treatment Directive.
Notes to editors
The Planning Inspectorate is the independent government agency responsible for operating the planning process for Nationally Significant Infrastructure Projects (NSIPs). The Infrastructure Planning Order (Waste Water Transfer and Storage Order) 2012 enables major projects, such as the Thames Tideway Tunnel to be designated as an NSIP Thames Water’s first phase of public consultation for the project ran from 10 September 2010 to 14 January 2011. The second phase ran from 4 November 2011 to 10 February 2012.
