Reviewed by Joe Ashwell

First reported on New Civil Engineer
30 Second Briefing
Galliford Try has secured a £47.5M contract from Thames Water to deliver the Camberley Sewage Treatment Works Flow Compliance project, upgrading a works previously criticised as a “cess-pit”. The scheme will focus on improving hydraulic capacity, process performance and resilience to meet tighter environmental permits and storm-flow compliance obligations. Civil and MEICA scope is expected to include new or uprated inlet works, flow control structures and treatment units, with construction staged to maintain full treatment during the upgrade.
Technical Brief
- £47.5M capex package awarded solely for Camberley STW Flow Compliance upgrade works.
- Contract let directly by Thames Water to Galliford Try, indicating single-prime delivery responsibility.
- Works are framed as a “major scheme”, implying multi-year delivery and complex phasing.
Our Take
In our database, Galliford Try features across highways, water and energy work, and its infrastructure MD has recently flagged a multi‑year upswing in UK infrastructure spend, so this Camberley Sewage Treatment Works contract likely forms part of a deliberate push to deepen its water-sector order book.
Galliford Try’s recent use of a green hydrogen fuel cell generator on a National Highways compound suggests Thames Water can expect pressure for lower‑carbon site operations at Camberley STW, aligning construction practices with tightening environmental expectations on utilities.
Alongside its position on National Grid’s major civils framework and Sovereign Network Group’s £750m housing framework, this Thames Water award reinforces Galliford Try’s strategy of securing recurring framework and programme-style work rather than relying on one‑off infrastructure jobs.
