Pipe laying under water requires the use of tried and tested techniques and the greatest possible care, because the difficulties involved in underwater maintenance make any servicing time-consuming, difficult and costly. Underwater laying techniques suited to the site topography and hydraulic conditions of the stream to be crossed can be used with ductile iron pipes.
A drinking water supply or irrigation project can include an underwater section:
crossing a stream on the pipe route,
intake in a lake or impounding reservoir in altitude,
laying along a stream bed.
Technique
The solution chosen must comply with the following constraints:
- resistance to internal and external pressures,
- long-term guarantee of leaktightness and infiltration tightness,
- mechanical resistance of pipelines to external stresses (changes to pipeline profile, embankment erosion, floodwaters, etc.),
- ease and speed of laying given the sometimes sudden variations in water level,
- pipe, fitting and joint compatibility with the laying techniques employed.

Awesome, I was literally just wondering how pipelines are installed but you are a wizard with this timing. I feel completely satisfied, very educational 🙌

In India it will be very useful in laying fiber optics cable. Very good👌

You forgot to push the cuttings out pal
