Civil engineering and infrastructure specialist Barhale has been selected by Thames Water to install more than 4km of new trunk main in south east London as part of plans to build additional capacity in the area.

The £8.6M project will install a DN800 DI pipeline between Crooms Hill, Greenwich and Ordnance Crescent, adjacent to the Blackwall Tunnel approach and the O2 stadium, on the Greenwich Peninsular.

The programme of works will be a key element of Phase Two of the construction of new water infrastructure between Deptford Water Treatment Works (WTW) and the Greenwich Peninsular and will help Thames Water meet water demand for ongoing and future development.

Barhale was also responsible for the completion of Phase One – the Deptford to Greenwich Main – which ran from Broadway Fields near the Stephen Lawrence Centre along Greenwich High Road to Crooms Hill.

The new main will connect to an existing DN800 water main at Crooms Hill before crossing Greenwich Park. It will be the largest construction project to be undertaken in the park since the 2012 London Olympics.

Barhale contracts manager James McKenzie, described the works as a key part of Thames Water’s strategy to ensure there is a sufficient capacity to meet future requirements.

“This part of south east London is seeing a lot of development activity at the moment and that is only likely to continue as cross-river access improves thanks to the new Riverlinx project,” he said. “The new main between Crooms Hill and the Peninsular will be another important step towards meeting increased demand and building greater resilience in the network.

“We are particularly pleased to have secured the Phase Two work after having been able to play an important role in the Phase One works and look forward to working with the Thames Water team to bring the project to completion in March 2024.”
