A joint venture between Bam Nuttall and Doosan Enpure has been appointed by Thames Water to relocate a sewage-treatment works in Guildford, the UK.

The scope of work under the five-year design, build and commission contract involves demolition of the existing 60-year-old facility to construct new housing on the site.

A 1.5km, 1,500mm-diameter tunnel will also be constructed to transport the sewage from Guildford’s existing sewer network to the new site.

The project will include construction of facilities to perform the four stages of treatment before the treated water is returned to the River Wey through a newly built outfall.

Guildford Borough Council will fund the new, modern sewage-treatment works, which will be built at a former landfill on the Slyfield Industrial Estate.

The new works will be Thames Water’s first new, modern sewage-treatment works since 2005 and will be designed to allow for future expansion to meet the demand from Guildford’s growing population.

Thames Water capital delivery director Francis Paonessa said: “As well as creating space for new homes in the town, the scheme will allow us to build a modern sewage works which will be able to support Guildford’s growth in years to come.

“This will be the first new sewage works to be built by Thames Water since Reading STW opened more than 15 years ago and shows our commitment to constantly improving the service we offer our customers.”

Construction work of the project is scheduled to commence in the autumn of 2022 and new sewage treatment infrastructure is planned to be completed in early 2026.
