APPLICATION OF GEOPHYSICAL SURVEYS FOR SEWER DESIGN
In areas where the depth to bedrock can be extremely shallow, a subsurface investigation becomes an important and sometimes costly component of a sanitary sewer design. Traditional methods such as digging test pits or completing borings are intrusive and provide limited information with regards to the nature of the subsurface over large areas. In recent design projects, the feasibility of a variety of alignments was evaluated and a geophysical survey method was employed to investigate the bedrock in the various areas. This proved to be a cost-effective and accurate method for investigating the depth to bedrock that minimized surface disturbances and provided continuous subsurface information.
