They are used in cities, parks, forests and places where the depth of installation makes the techniques more economical than open trench installation.
Advantages of trenchless technologies include:
- Enhanced worker and public safety.
- Reduced risk of damage to nearby nature, structures and utilities.
- Reduced disruption to surrounding businesses, residents and the environment.
- Cost effectiveness.
- Possible uses for obstacle crossing where regular open-cut methods are not suitable.
