Two sewer siphons are currently situated in sediment underneath the Naugatuck River upstream of Kinneytown Dam and will need to be moved to facilitate the removal of the dam. Engineering Consultant CDM Smith was hired with funding from a National Oceanic and Atmospheric (NOAA) grant award for the Kinneytown Dam Removal Project, and is working with the Town of Seymour and partners to design the relocation of two sewer siphons.
The NVCOG secured $3.4m in FY24 Congressionally Directed Spending for the sewer relocation construction. An additional FY25 CDS request for $1.72m was included in the Interior, Environment, and Related Agencies spending bill, and is pending a final FY 2025 budget adoption. The NVCOG intends to seek funding from State and Federal sources to fund the balance of the project.
The project design started in September of 2024, Engineering Consultant CDM Smith was hired through an approved procurement process and is working with the Town of Seymour and partners to design the relocation of two sewer siphons currently located in the impoundment above Kinneytown Dam. The project will result in an important update to the sewer system as the current siphons are over 50 years old.
The project deliverables will be completed in phases. For the Planning phase a technical memorandum that summarizes the work that will be completed, comparing alternatives, and providing a recommended plan. For the Design, Permitting, and Bidding phase final construction documents of the recommended plan suitable for bidding will be completed. The final phase will be Construction.
