The Wastewater Capacity Improvements Project consists of the construction and replacement of sanitary sewer infrastructure within Basins 4 and 6 in the City of St. Helens. The project is intended to increase system capacity, improve reliability, and address existing conveyance deficiencies in key portions of the collection system.

Work includes installation of approximately 12,449 linear feet of new sanitary sewer pipe of varying diameters, including 10-inch, 12-inch, 15-inch, 18-inch, 24-inch, 27-inch, and 28-inch pipe. Pipe materials include PVC and HDPE. Portions of the work will be constructed using trenchless methods, including installation of the 24-inch PVC pipeline and approximately 1,564 linear feet of 28-inch HDPE pipe. The project also includes a trenchless crossing beneath an active railroad.

Additional improvements include rechanneling 18 existing manholes and installation of 49 new manholes. Associated utility and surface restoration work includes approximately 150 linear feet of water line relocation, 383 linear feet of storm drainage pipe replacement, trench backfill, asphalt paving, sewer system testing, and restoration of disturbed landscaping and surface features.

A portion of the work occurs within the U.S. Route 30 right-of-way and will require coordination with and inspection by the Oregon Department of Transportation.

This project is funded in part through the Clean Water State Revolving Fund (CWSRF). As such, the Contract Documents include federally required provisions. Contractors shall comply with all applicable CWSRF requirements, including but not limited to federal labor standards (including Davis-Bacon wage requirements), American Iron and Steel (AIS) provisions, and applicable environmental and reporting requirements.
