Crossing

Definition - What does Crossing mean?

Crossing refers to the process of passing gas, oil, water or sewer pipelines under environmentally sensitive areas such as wetlands, estuaries, rivers, lakes and protected areas.

Trenchless technology has enabled this by making drilling possible below the bed of the sensitive areas using directional drilling techniques. Horizontal directional drilling (HDD) has become an important part of the pipeline industry because of its environment-friendly handling of sensitive locations.

Trenchlesspedia explains Crossing

Water bodies are very important and well protected geological features and are commonly found on landscapes across the country. Using traditional cut and install methods would harm the aquatic life, disturb the balance of life-sustaining minerals in the water, harm the stability of the manipulated side slopes and much more.

The crossing of these water bodies using HDD eliminates the need for open trenching and associated complications altogether. The excavations needed are only the entry and exit pits at the launch and reception sites. This altogether bypasses the water body by passing directly underneath and creates no disturbance for aquatic life or to the structural integrity of the land mass.
