In the past, any problems with the water main leading to a house or the sewer line leading away from a house meant major damage would be inflicted on the lawn. Since it was easy to know that there was a problem but impossible to know exactly where the problem was located, long trenches had to be dug to expose the entirety of the pipe in question.
But those days are over! Today, we use trenchless technology. This means your lawn will remain undisturbed when your sewer line or water main requires repair.
