Gravity Pump Stations
Gravity pump stations are pretty simple. They have an area for
holding the sewage, usually referred to as the wet well. The wet well can
be large or small. The purpose of a wet well is to collect sewage before it
is pumped on its way to the treatment plant. After a quantity of sewage is
collected in the wet well, the sewage is pumped under pressure, through force
mains. Pumps can move sewage a lot faster than the sewage can flow by means
of gravity, and can also move the sewage uphill, over a great distance fast
and also under the lake, allowing us to get the sewage from the North side
of the lake to the South side where the Treatment Plant for SCCLSD is located.
