Knife River Historic Indian Village Visitor Center Septic System and Plumbing Replacement

The National Park Service is inviting bids for construction services to replace the septic system at the Knife River Historic Indian Village Visitor Center in Stanton, North Dakota. This project involves replacing interior sewer piping, reworking the exterior lift station and valve vault, and constructing a new exterior septic system. The existing system has experienced issues with solids evacuation, leading to backups and damage. The work is to be completed within 120 calendar days of the Notice to Proceed, with on-site work impacting the existing system to occur after Labor Day. The estimated magnitude of this project is between $500,000 and $1,000,000.
