Once the larger particles are removed, the water undergoes sedimentation, where it is allowed to sit in large basins. During this time, heavier particles settle to the bottom, forming sludge that can be removed. The next step is often filtration, which can involve layers of sand, gravel, and activated carbon to further eliminate finer particles and chemical contaminants.
