The biggest single construction project in Norwich Public Utilities’ history is expected to begin this fall, and like building a new school, the utility will need to ensure the existing obsolete sewage treatment plant stays open while building its $200 million replacement on the same site. NPU General Manager Chris LaRose said the upgrade project must be done now to avoid state fines for water contamination caused by the outdated plant, which frequently sends untreated sewage into the Thames River following major storms and nitrogen contamination. The new plant construction is expected to break ground this fall and take five years to complete. As with a new school construction project, the old plant must continue to operate and remain in compliance with state and federal environmental regulations during construction.
