Most wastewater undergoes secondary treatment as well as primary treatment. The most common method is to sprinkle or trickle the water over a bed of sand or gravel. As the water filters downward, it is put into contact with oxygen and microorganisms, which work together to break down the organic matter in the water. The water is then usually chlorinated before it is released into the environment. In a few places, the water undergoes tertiary treatment, which involves a variety of processes to purify the water even further.
