Today, water providers have many other options for upgrading water mains besides disruptive dig-and replace techniques.  This video looks at so-called "trenchless" pipe rehab techniques.

The video provides an excellent overview of cleaning systems (flushing, cable-attached devices, fluid-propelled devices, and power boring); lining systems (cement mortar, epoxy, slip, modified slip, and cured in place); and pipe-bursting systems (pneumatic, hydraulic, and static). VHS, 24 minutes.
