Job Report Lismore - Rehabilitation and upgrade of a leaking DN 225 uPVC Class 9 water main - March 2016

The Lismore City Council was confronted with the rehabilitation of a leaking DN 225 uPVC Class 9 water main located at Elizabeth Street. The first section of the pipe runs downhill into a gully with a length of 170 m and a height difference of approximately 35 m where a scour valve is located. The second section runs from the scour valve uphill with a total length of 290 m and a height difference of almost 50 m. The pipe coverage was up to 3.8 m and power supply lines were in proximity to the construction site. Therefore, the Lismore City Council was looking for a trenchless solution that could repair the leaking pipe, increase the pressure rating to 16 bar and maintain the hydraulic capacity.
