In 2016, the state Office of Policy and Management (OPM) authorized $1.35 million for NVCOG to conduct a regional wastewater treatment consolidation study. The study will provide a preliminary analysis to help determine the region's ability to increase capacity for properly treating wastewater in a consolidated facility or facilities, thereby leading to a reduction in long-term state and local capital improvements and a reduction of user fees.
Specifically, wastewater treatment plants in the municipalities of Naugatuck, Beacon Falls, Seymour, Ansonia and Derby will be analyzed for potential consolidation and/or the sharing of services. In addition to providing potential recommendations to mitigate costs and to mitigate capital expenditures that will be required for upgrades to the wastewater treatment plants located in these communities, the study is designed to set an example for other communities throughout Connecticut in consolidating plants and reducing costs. The NVCOG conducted a Request for Proposal for study consultant services in mid-2017. Following a Quality Based Selection process, Black & Veatch, of Overland Park, Kansas, was selected vendor. The firm formally began the study process in April 2018.
The study will be conducted in two phases. Phase 1 tasks will include a review of existing planning documents and related and assessment of existing wastewater treatment facilities and collection system infrastructures. It will also provide an estimation of 20-year wastewater flows and load projections for each participating municipality summarize existing wastewater system management and governance for each participating municipality, and identify potential opportunities for cost savings and operational efficiencies through alternative approaches to system management and governance structure. In addition, Phase 1 will identify a long list of wastewater regionalization alternatives that appear to have initial merit for regionalization.
With OPM’s authorization to proceed following the conclusion of Phase 1, Phase 2 will include an Environmental Impact Evaluation (EIE) and more extensive technical and engineering analysis, as well as identify a short list of alternatives and preferred alternative(s) to the systems currently in place.
