These massive, concrete basins are the first stage of purification. Raw water is pumped into these tanks, allowing heavy particles and debris to settle at the bottom. The murky water slowly clears, revealing layers of sediment that are periodically dredged out. This area is crucial for removing large contaminants before the water moves to finer filtration stages. This is a room within the Main Filtration Plant, and can only be accessed once inside the plant.

The tanks are lined with rough, gray concrete, and the surface of the water is often disturbed by the settling debris. Occasional bubbles rise to the surface, and the air is thick with the earthy smell of wet soil and decaying organic matter.
