Murphy appoints Aecom to design Bristol sewer

Murphy

December 07, 2018 – J Murphy & Sons has retained Aecom as lead designer for its £45m north Bristol relief sewer project.

The north Bristol relief sewer is a new 6.5km tunnel for Wessex Water that is designed to reduce flood risk and increase stormwater storage capacity to accommodate developments in Bristol and south Gloucestershire.

The tunnel will link the Frome Valley relief sewer to the Bristol trunk sewer, directing sewage around north Bristol to Wessex Water’s sewage treatment works in Avonmouth. Passing under the M5 motorway and the Henbury Loop freight railway, most of the tunnel will be built deep underground with some sections reaching as much as 30 metres below ground level.

Aecom head of tunnelling Steve Woodrow said: “Tunnelling under the M5 and operational rail services, and connecting with the existing sewage system, this complex tunnel is a vital part of Wessex Water’s strategy to future-proof the sewerage network for communities in Bristol. Aecom brings its expertise on a number of major water infrastructure tunnelling schemes to the project, including Tideway and Deephams sewage treatment works.”

Murphy was appointed principal contractor for the £45m project earlier this year. As lead designer, Aecom will deliver the detailed designs for the project, with construction due to start in late 2019.

Aecom is providing civil, hydraulic, mechanical, electrical and structural design services, as well as environmental consultancy for the scheme.
