rock river water reclamation district four rivers sanitation authority 27-409-Specs-Complete-WATERMARKED.pdf

This is a specification document for the Rock River Water Reclamation District and Four Rivers Sanitation Authority sanitary sewer system lining project in Illinois. The project encompasses the installation of cured-in-place pipe (CIPP) lining for approximately 19,250 linear feet of existing sanitary sewers ranging from 8 to 24 inches in diameter. The scope of work includes reinstatement of existing service connections on lined sewer mains, restoration of all appurtenances as detailed in contract documents, and provision of all necessary labor, materials, equipment, and supervision. The project is designed to rehabilitate and extend the operational life of the existing sanitary sewer infrastructure without requiring full pipe replacement.

The specifications document provides detailed technical requirements for the CIPP lining methodology, material standards, quality assurance procedures, and performance criteria that contractors must meet. The specifications include requirements for pipe cleaning, preparation, installation of the cured-in-place liner, testing protocols, and restoration of service laterals to ensure proper system functionality. Contractors must demonstrate compliance with industry standards and possess appropriate equipment and expertise to execute the trenchless rehabilitation work. The document establishes the technical framework and evaluation criteria upon which bids will be assessed and contract performance will be monitored throughout project execution.
