| Abstract |
The purpose of this project was to determine whether the trenchless method of sewer construction had inherent cost, safety and other advantages over conventional methods of sewer construction. Under similar site conditions, the trenchless method was more cost effective than conventional means based on the actual unit bid price (50%), on complete sewer installation including manholes, wyes and laterals (16%) and on labor savings (23%). Eight inch polyvinyl chloride pipe with rubber gasketed joints was used in the conventional area, whereas eight inch polyvinyl chloride solvent welded pipe was used for the trenchless method. The trenchless method does not appear to be suited for urban areas where significant subsurface utilities exist, nor where rock or boulders exist in high density. However, the system is uniquely adapted to high water table areas, and its flexibility of application under varying soil conditions is wide ranging. The potential for infiltration is significantly less and, with proper field control, the trenchless method results in less deflection and horizontal and vertical misalignment. With open trenching reduced to a minimum, the method is safer than the conventional technique, particularly where deeper cuts are required. From an environmental standpoint, the trenchless method provides less disruption to traffic, and represents an improvement in sediment runoff control and noise reduction. |
