The NitROE® WWTS have been installed on Martha’s Vineyard (MV), Nantucket, Cape Cod (Cape) and the South Shore of Massachusetts. Additional NitROE® units are in design phase for other regions of Massachusetts and the New England area.

KleanTu®’s NitROE® WWTS is listed on the Massachusetts Department of Environmental Protection’s Best Available Nitrogen Reducing Technologies (BANRT) list under a provisional permit.
