Three trickling filters,150 feet in diameter and 35 feet high
Each trickling filter contains 5.3 million square feet of surface area, (enough to cover the Staples Center building almost six times)
Solids contact re-aeration basins 20 feet deep and 12,400 square feet in area (about one quarter of a football field)
Six circular clarifiers,135 feet in diameter and 23 feet deep
