Completed flood scheme


McPhillips have completed the latest phase of the Denbigh & Corwen Flood Risk Management Framework. Having already completed two phases, phase three was the most technically challenging involving upgrades to the existing drainage infrastructure in the heart of Denbigh Town Centre. Our input through early contractor involvement was critical and we were able to assist the designers in making the project workable through the extensive use of no-dig techniques.

The scheme involved pipe jacking 120m of 1200mm diameter pipe and auger boring 140m of 600mm diameter pipe at depths of up to 5m with the construction of 10 new manholes. Connections into existing culverts were contractor design & build. A high number of uncharted services were encountered and these involved the excavation of a large number of trial pits and re-design of pipe runs on a number of occasions. Traffic management was McPhillips designed and managed and no-dig construction methods meant that road closures were not required.
Community liaison was extensive and public communication was achieved not only through traditional methods but the Project Liaison Officer was responsible for creating the local weather station, manning the Project stall at the St Davids Day celebrations, updating the project website (, Twitter account and visiting the local Yale College.
