Funding is for Phase III of the NBC’s CSO Abatement Program, which is estimated at USD 760M. The centerpiece of Phase III is a 30ft (9m) diameter, 2.2-mile-long (3.5km) deep rock tunnel under Pawtucket and Central Falls to capture and store storm-related sewage overflows and transport those flows to the NBC’s Bucklin Point Wastewater Treatment Facility for full treatment.

“We know Rhode Islanders value a clean and healthy bay,” said NBC Chairman Vincent Mesolella. “We’re very proud of infrastructure investments Narragansett Bay Commission ratepayers have made over the past two decades to mitigate the century-old issue of CSOs and the NBC is confident that this final phase of the CSO project will result in a bay that will be a beloved resource for our children and grandchildren. The WIFIA loan also ensures that the cost of this ambitious clean water project will be mitigated for our ratepayers.”
