Wolsingham Sewage Treatment Works: innovation saves client more than £1M

Learn how our innovative and sustainable approach to this project yielded never-before-seen results, created a buzz and won awards.

While a standard solution for the STW might have typically included the demolition and in situ casting of new concrete structures, the project team decided early on to approach this program with an entirely different mindset. In a move that was completely different than anything the water industry had ever seen, our team, as project designer, and Tilbury Douglas Construction, as principal contractor, decided along with the client, Northumbrian Water, to fabricate everything needed for the project – offsite. An approach commonly referred to as a modern method of construction.

What would have typically involved a four-week build with concrete was completed, instead, in less than seven days.
Essentially, what we accomplished on this project was the equivalent of a new build, using the same exact footprint, but at a fraction of the cost.
