Lead Pipe

Beauchamp Road, Edinburgh – 1/2″ Lead Pipe Replacement

KOBUS Services Ltd were invited by Clancy Docwra to undertake a demonstration of the KOBUS Pipe Puller to Scottish Water and the local Clancy Docwra contract management and field operations team in Edinburgh. In early 2012 Clancy Docwra successfully won a major role in the 5 year UK £1.2bn networks R&M contract for Scottish Water with the KOBUS Pipe Puller forming an integral component of the innovative and cost-effective approach proposed. The purposes of this demonstration were therefore firstly to show the Clancy Docwra Contract Manager the speed, effectiveness and safety of the Pipe Puller and secondly introduce the KOBUS Pipe Puller to the Clancy Docwra field operations teams.

The pipe replacement undertaken by KOBUS Services Ltd was carried out on a live site in a suburban road in southern Edinburgh. Under normal circumstances this long-side cross road replacement would have been undertaken via moling although this is a potentially risky approach if there are significant numbers of services in both the highway and the pavement. The pipe itself was a 1/2” diameter lead pipe and 6m in length. In addition, the City of Edinburgh Council had imposed strict requirements on both the nature of road openings and the quality of highway reinstatement.

The 6m cross-road lead pipe was successfully removed and replaced by MDPE pipe in 181 seconds. The time on site for this pull was approximately 43 minutes from cutting the supply to re-connection. The excavation for this demonstration was also slightly deeper than normal although this proved no obstacle for the Pipe Puller.

Throughout the operation, Beauchamp Road remained open with no disruption to traffic. The minimal impact of Puller operation on the highway also ensured the City of Edinburgh Council requirements for reinstatement could be fully met.

The work was undertaken under standard Scottish Water/Clancy Docwra health & safety procedures. There were no reported incidents in respect of either service strikes (HSG47) or operator activity.
