Back River Wastewater Treatment Plant, Egg-Shaped Digesters

Baltimore, MD

Client

The Crom Corporation

Completion

1992

Crom Corporation designed and built two 3.0 MG egg-shaped sludge digesters for Baltimore's Back River Wastewater Treatment Plant. SGH performed a peer review of the structural design of the new digesters. Although egg-shaped digesters are rather common in Europe, they were relatively new to the United States. At the time they were built, the digesters were the largest in the United States.
