Ridgefield starts second phase of Route 7 sewer project, despite delays to treatment plant upgrades

Construction is poised to start on the second phase of the town’s $55 million upgrades to its sewer infrastructure, even as the first half of the project is behind schedule. Crews have marked spots along the roads and begun drilling so they can install an underground force main pipe that will extend from the South Street Wastewater Treatment Facility that’s undergoing renovations and the Route 7 Pump Station, which will be demolished and replaced with a new pump station. DEEP approved an interim plan to use a temporary chemical feed system to remove some phosphorous, but gave the town until April 2023 to finish the project and meet the new requirements, said Jon Pearson, vice president with AECOM Technical Services, the engineering firm for the project. The contractor has submitted a document explaining why the project has faced delayed, Pearson said. Those reasons include material delays and labor shortages, but the town has contended some of the claims, he said.
