Aspects are detailed of the excavation and preparation of trench, the installation of pipe and fittings, connection and assembly of joints, water service installation, and the setting of valves, hydrants, fittings and specials. The disinfection of water mains, hydrostatic testing of water mains, pipeline backfilling operations, and restoration of surface improvements are covered, as well as maintenance and final clean up operations.
