Micro Pipe Bursting

The City of Greensboro, North Carolina has decided that replacing water mains via static pipe bursting provides the least disruption and social impact to the community. Communities served by 50 mm (2 in) cast iron mains, that distribution system models identified as being undersized, were targeted for upsizing. This previously unattainable feat was made possible by a two pass bursting system that used a unique combination of static bursting rods created by KRG Utility and TT Technologies. To date, more than 915 m (3000 feet) of 50 mm (2 in) cast iron water main has been upsized with 150 mm (6 inch) fusible PVC. This new technology has provided the City of Greensboro with a trenchless replacement option for maintenance heavy 50 mm (2 in) water mains. The newly installed 150 mm (6 inch) lines provide increased capacity and also allow for the addition of hydrants for fire protection.
