For example, if you stir sugar into tea, the action of stirring causes the sugar to be suspended in the tea. If you leave the tea for a while, some of the sugar will settle our. It follows that the flow of water must be monitored in sewer lines. If the water is moving too slowly the solids settle out and the in will become stopped up. There are twelve lift stations in Kirksville.
Lift stations are low points where gravity takes sewer water.
The station then lifts the water by pumping it up to a point where gravity can carry it to the waste water plant. This gas will corrode the collection system used to transport water if it is not controlled. Each lift station has two pumps and a basin that can hold excess waste water should there be an emergency. From there it goes to a grit chamber which settles out some of the heavier materials in the waste water. Further filtering is done by a mechanical bar screen which removes things like rags, stick and other debris.
