21st Avenue Sewer Bypass Project

The City of Caldwell, Idaho is inviting bids for the 21st Avenue Sewer Bypass Project, with submissions due by 1:00 pm on July 25, 2025. The project involves constructing a new 24-inch gravity sewer main to create a permanent bypass for an existing sewer lift station that will be decommissioned. Key tasks include excavation, pipe and manhole installation, trenchless casing work across 21st Avenue, backfilling, testing, and restoring the surface. The scope also encompasses connecting the new sewer to existing infrastructure, abandoning the old lift station, coordinating utility work, and performing CCTV inspections of the new sewer and manholes. A portion of the bypass was completed in 2021, and this contract aims to finish remaining elements not previously completed. The project is valued between two and five million dollars and is categorized under NAICS code 238910. The solicitation was posted on June 11, 2025, and is managed by the City of Caldwell, Idaho. Interested bidders can contact TJ Frans via email or phone for further details. Additional project information and bidding details are accessible through the city's procurement portal.
