Silver Creek Trunkline Sewer Rehabilitation
BC&A provided planning, design and construction engineering to rehabilitate the Silver Creek trunk sewer line in Park City, Utah. The project location spanned from the SR 224/SR 248 intersection, along the SR 248 right-of-way, and the Silver Creek corridor to the Silver Creek Water Reclamation Facility. The project included preliminary design and evaluation, final design, and construction services for rehabilitating approximately 7.27 miles of existing 18 – 30-inch RCP sewer pipe. Approximately 500 feet of existing 24-inch ductile iron pipe located below SR 248 was replaced. Of the 500 feet, 262 were within a steel casing which resulted in using open cut and boring methods for installation.
The project featured the use of polymer manholes for both, newly installed manholes, as well as the existing manholes that were severely deteriorated and required replacement.
The project included access improvements and required easements as well as extensive environmental permitting and agency coordination. The project is located in what is known as the EPA OU soil contamination zone and required special soil handling, water and soil monitoring, and discharge permits.
