How water supply lines reach a house without trenching

As part of Water Project 3, between Stockton Street and Central Avenue, just north of Kettleman Lane, new water mains and water supply lines are replacing backyard lines. It's a scene that will become more common in Lodi as part of the water meter installation project, which kicks off in 2011.
The project includes installing new water mains, some as deep as 8 feet below street level, and new water supply lines to homes.
Here are a couple photos from the water main installation on Central Avenue:

Here's a slideshow and short movie of how the service lines are brought from the sidewalk to the house without trenching the lawn.
