Document Description
The proposed Project includes the rehabilitation of the existing Llano Road Trunk pipeline, a critical wastewater collection facility, which carries approximately two thirds of the City’s wastewater flow to the Laguna WTP. The existing pipeline is nearly 50 years old and must be rehabilitated to prevent failure of the system and/or more impactful actions that would be associated with replacement. The scope of the Project includes rehabilitation of approximately 8,170 linear feet (LF) of the 66-inch reinforced
concrete pipe (RCP) trunk sewer. It also includes a conditions assessment of the existing manholes along the alignment and rehabilitation of the manholes as recommended at the conclusion of the condition assessment field investigation.
