2026-2027 Sanitary Sewer System Lining

Rock Island County is soliciting bids for sanitary sewer system lining via cured-in-place pipe (CIPP) installation for approximately 19,250 linear feet of existing sanitary sewers ranging from 8 inches to 24 inches in diameter, with proposals due September 22, 2026.

Contractors must perform pipe cleaning, preparation, liner installation, testing protocols, and service-lateral restoration. The detailed technical requirements, material standards, quality assurance procedures, and performance criteria are specified in the contract documents, which establish the framework for bid evaluation and contract performance monitoring. Contractors must demonstrate compliance with industry standards and possess appropriate trenchless rehabilitation equipment and expertise.

Place of performance is Rock Island County, Illinois.
