Sedimentation tanks remain a cornerstone of wastewater treatment, playing a crucial role in the removal of suspended solids and the overall efficiency of water purification processes.

One of the plant’s biggest problems: separating solids from wastewater. All five of its primary sedimentation tanks, which remove solids, had been down since March 2023.
