The benefits of trenchless technologies and their practical applications in industry can not be overlooked. Industrial utility operators need to assess the advantages and disadvantages of trenchless versus traditional open cut methods when planning for rehabilitation or replacement.
Trenchless Technology has the following advantages.
- Cost: Substantial cost savings are possible. However, even when trenchless methods are more expensive, such technology may be the best alternative because of other considerations discussed below.
- Enviromental Effects: Less soil is disturbed so impacts on adjacent organisms and water bodies can be reduced significantly.
- Disruption: Traffic delays are reduced or eliminated, as is heavy truck traffic associated with pipe excavation deep below the roadway.
- Speed of Installation: Construction often takes less time, regardless of the road fill depth.
- Safety: Many safety concerns associated with steep-excavation slopes, work inside trench boxes, and worker exposure to traffic may be eliminated or reduced.
- Less Engineering: Less surveying, fewer design calculations, and fewer drawings and specifications may be required.
- Fewer Unknowns: Minimal ground disturbance results in fewer contingencies associated with subsurface conditions with pipe lining options.
