Mackley has been contracted by Portsmouth Water to carry out a project that will maintain water supply to parts of Hampshire, including the town of Gosport.
Hampshire County Council is currently carrying out works to provide a guided busway transport route connecting Fareham in the north to Gosport in the south.
In order to complete their scheme, two existing Portsmouth Water assets require diversion. One – a 30” pre stressed concrete (PSC) water main, located within the disused railway corridor – is a critical supply trunk main for Gosport.
The second is a 180mm Polyethylene (PE) water distribution main which crosses the disused railway line near the Rowner Road bridge and provides localised supply.
The project requires careful co-ordination with the main busway works which are taking place at the same time.
PSC water main
This element of the scheme includes the replacement of approximately 220 metres of existing 30” PSC water main – to respective connection points on the existing 24” main to the west of Henry Cort Way and the existing 18” main to the east of Henry Cort Way.
New ductile iron (DI) pipework will be used to replace the existing 30” PSC main in this location.
PE water distribution main
These works will involve the replacement of approximately 70 metres of 180mm PE distribution main, including connections to the existing water main at specified points.
