Located in New Haven County, Connecticut, in the eastern USA, the wastewater treatment plant in Meriden has a design inlet flow of 43,911 m3/day (11.6 mgd) with a maximum inlet flow of 143,386 m3/day (38.0 mgd). Upgraded in the 1960s and 1980s, the plant has been in existence since the 1800s.

In 2007, the plant initiated a series of major upgrades that had been approved to address its twenty-year growth. Among them were a fourth 1st stage sediment basin, a fourth 1st stage reactor and new, more efficient blowers to upgrade the aeration system.
