This organic matter provides food for the bacteria that break it down. However, the concentration of oxygen in freshly produced sewage is low. This is because the sewage has not had time to mix with air. As a result, aerobic activity is low in freshly produced sewage.<\/p>\n<p>At sewer pipes, the concentration of oxygen is even lower than in freshly produced sewage. This is because the sewage is flowing through the pipes and does not have time to mix with air. As a result, aerobic activity is very low at sewer pipes.<\/p>\n<p>In sewer treatment plants, the concentration of oxygen is high. This is because the sewage is mixed with air in the aeration tanks.
