NORWICH – Mayor Joe Maiurano, joined by Public Works Superintendent Carl Ivarson, visited the city’s Wastewater Treatment Plant on Route 12 south last week to observe the installation of three new Rotating Biological Contactors (RBC).

Thanks to a $500,000 grant through the office of Congressman Michael Arcuri, as part of a $4.5 million project in conjunction with the United States Environmental Protection Agency, Ivarson reported that 12 of the 18 contactors, a kind of biological waste filter, have now been replaced, and the project is tentatively scheduled for completion in the next 40 to 50 days.
