I am working on a project to reduce odor for a sewer system. In the sewer system there are two lift stations with large storage volume and low flows. Have any of you ever filled in a portion of the wetwell with concrete blocks or concrete to get the pumps to cycle more often and keep the sewage moving? There are odor problems at these stations and they pump directly to the sewer plant and they have odor problems there also. The odor problems occur around 9 pm and 7 am. The lift stations were designed for future growth that has not happened. They are set up to chemically treat for odor but I am trying to help optimize the stations so they can reduce the amount of chemicals.
