During works to build a new road in Chorley, Lancashire, an old draw off pipe was discovered. As the pipe was not shown on maps of the area, its precise location and route had to be determined.

Mott Macdonald called us in to trace the line of the pipe and to cap it off. The pipe was drilled and tapped. Compressed air was introduced into the pipe and a visual check was carried out to identify the location of the pipe mouth and to check for any joints or fractures.
Once the line of the pipe had been established, the pipe was disconnected and sealed off.
