System for determination of line and level for trenchless construction

A method of ascertaining a line and a level of a jacked or rammed casing comprising the following steps:

• activating a light emitting device disposed within a housing assembly, the housing attached to the casing, wherein the housing assembly comprises a water discharge disposed adjacent to an opening which penetrates into an interior of the casing;
• and
• pumping a stream of water through a line connected to the housing assembly wherein the housing assembly is configured to direct the stream of water to the water discharge, wherein the stream of water is illuminated by the light emitting device resulting in an illuminated stream of water flowing into the interior of the auger casing.

An apparatus configured to ascertain a line and grade of a lead casing installed within a trenchless construction system, wherein an auger is disposed within the lead casing, the apparatus comprising:

• a housing assembly for attachment to the lead casing installed as a component of the trenchless construction system, the housing assembly comprising a water discharge, and a light emitting device disposed adjacent with the water discharge, wherein the water discharge is disposed adjacent to an opening which penetrates into an interior of the lead casing;
• and
• a hose having a first end attached to the water discharge, the hose having a second end attached to a water source, wherein a stream of water flowing from the water discharge into the interior of the lead casing is illuminated by the light emitting device.
