The flocculation pools are the second phase of water treatment, and the first visible phase of treatment. The flocculation phase is divided between three separate pools- the larger main pool is used during regular operation, and the two smaller auxiliary pools are used as backup treatment pools in the event that there is an issue with the main pool.

The flocculation phase is divided between three separate pools- the larger main pool is used during regular operation, and the two smaller auxiliary pools are used as backup treatment pools in the event that there is an issue with the main pool. The main treatment pool is fed by four independently operable water pumps, which can be activated independently depending on the plant's load. The main pool also contains the second flushing line outflow, which tends to cause the main pool to become contaminated. The auxiliary pools have significantly reduced capacity, and are operated only in the event the main pool fails or becomes contaminated. Unlike the main pool, the auxiliary pool can bypass the sedimentation phase, and be pumped directly to the filtration phase. | ||
Next to the flocculation pool is a service tunnel designed for carrying natural gas to the water plant. The fire alarm system is tied into this tunnel, and the tunnel can be sealed by a blast door in the event of an explosion. | Next to the flocculation pool is a service tunnel designed for carrying natural gas to the water plant.
