Project Description:

This contract was a considerable sized waste water scheme, spread over various locations between Crook Town Centre and Low Wadsworth Waste Water Treatment Works in County Durham.

The works were split between four phases and included the construction of 5 new CSO chambers with outfalls, the installation of approximately 5.2 km of pipelines and the abandonment of existing outfalls and pipelines.

In addition to traditional open cut drainage, trenchless technology in the form of pipe jacking and pipe bursting were also utilised on certain areas of this project to avoid unnecessary disruption to the surrounding areas.
