NTH is proud to be a recipient of a WWD Top Project award for their project, Clinton River WRRF Influent Pipeline Rehab. This project was also chosen as the Project of the Year for ASCE MI earlier this year.
A 66-inch diameter sewer line, the primary influent line for the Clinton River Water Resource Recovery Facility, crosses over the Clinton River in Pontiac. In 2015, staff observed cracks in the sewer and retained NTH to study potential causes and subsequently to provide design services for a permanent repair. Without intervention, the pipeline was certain to fail, creating an environmental and economic disaster to the surrounding community. With improvements now in place, the infrastructure will last well beyond the 50-year life span of the original pipeline and offers expanded opportunities for future pipeline inspections, maintenance, and simplified future system connection / expansion options.
