Water Line Laying involves the construction and installation of pipelines used to transport water from sources to distribution points. The process begins with route planning and surveying, followed by trenching and preparing the site. Pipes, typically made of materials like PVC, HDPE, or ductile iron, are fabricated and then laid along the designated route. The sections of pipe are joined through welding or mechanical fittings. After installation, the pipeline undergoes pressure testing to ensure integrity and leak prevention. The final steps include backfilling the trench, restoring the site, and conducting inspections to ensure safe and efficient water transport.
