I) The detention time (t) of a settling tank may be defined as the average theoretical time required for the sewage to flow through the tank. It is thus the time that would be required for the flow of sewage to fill the tank if there was no outflow.
(ii) In other words, it is the average time for which the sewage is detained in the tank.
Hence it is the ratio of the volume of the basin to the rate of flow through the basin.
