This is the ultimate settlement chamber. It works best in a gravity-feed configuration where the water is slowed by the standpipe so that there is the minimum amount of turbulence in the settlement area, thus the greatest amount of waste is allowed to settle.
The primary brushes can be removed as necessary for cleaning and the secondary brushes will trap the very finest particles.
The outlet will be positioned here if the water is flowing to a subsequent chamber mounted at the same level.
