Catford Raw Water Main & Shafts

As part of their development for over 500 new properties in Catford, South London, Barratt homes employed Barhale to construct a new 7.5m diameter permanent access shaft, over an existing Y-branch of a Thames Water Trunk Main Sewer. The developer planned to construct directly above the existing sewer and therefore required the shaft to provide man-entry access to the sewer to facilitate maintenance requirements in the future.

The works were carried out in a very restricted area, located in between two Network Rail tracks and delivered in conjunction with the construction of Barratt Homes’ Marketing Suite by a third party contractor. As such, all elements of the works involved constant stakeholder liaison and various approvals from asset owners such as Thames Water Developer Services and Network Rail.
