What is trenchless technology used for in wastewater collection?

Trenchless technology is utilized in wastewater collection primarily to install or repair sewer pipes with minimal disruption to the surrounding area. This method allows for the replacement or installation of pipelines without the need for extensive digging, which would typically involve large trenches and significant disturbance to the surface.

The advantages of using trenchless techniques include reduced labor costs, decreased impact on the environment, and less disturbance to traffic and existing infrastructure. This technology is particularly useful in urban areas where the disruption from traditional excavation methods would be more problematic due to the density of buildings and infrastructure.

In contrast, the other options either suggest processes that involve significant excavation or do not relate directly to the core purpose of wastewater collection systems involving pipes. Such practices would not align with the primary function and intention of trenchless technology.
