Millharbour Sewer Diversion

Services First Limited assisted in the legal and technical aspect of this project working closely with main contractor, C J O’Shea, who needed to divert an existing 1600mm diameter sewer, to enable the commercial development of apartments they were constructing for developer, Galliard Homes, to proceed as planned.

The work involved a 240m pipe-jack with three lateral connections, two end connections and associated manholes. It was originally intended to construct a new 1800mm diameter sewer to take the flow from the existing 1600mm diameter sewer but due to difficulties with the ground conditions it was agreed with the client and asset owner, Thames Water, that the new sewer could be reduced to 1500mm diameter.

J Browne were selected for this complex project as a result of previous work carried out for main contractor, C J O’Shea, their wastewater expertise as Thames Water’s largest wastewater repairs and maintenance contractor and due to their existing civils framework agreement with fibre optic network owner, Geo Metro.
