Pros and cons of a submersible sewage pump

As the name suggests a submersible sewage pump system is designed to be placed inside the water or the fluid that needs to be removed. There are various versions of the mechanical device which can be used for diverse applications some of which include boreholes, ponds, fountains, wells, bridges and sewage just to name a few.


One of the greatest advantages of submersible pumps is in its design. It is designed as a tightly contained unit with seals and watertight gaskets which help to keep the liquid out of the housing as well as the internal components. Such a design ensures that the pump will not leak or short circuit when submerged.

The other advantage is in the mechanism of operation in that the submersible pump uses direct pressure to push the liquid out of the hose or pump rather than using the suction technique. The method of direct pressure ensures that the pump can push liquids to a greater distance unlike the suction technique which doesn’t have enough power to push liquids to a greater distance.

Another great advantage with submersible pumps is that they are self-primed. This makes them very efficient as you do not require to prime them before you start. Other types of pumps like shallow well pumps and jet pumps require priming before you start.


Septic pump system is a mechanical device and just like other mechanical device it has its own shortcoming. One of the problems occurs when the seal or gasket ruptures causing the pump to leak.  Any form of leakage in the pump will cause corrosion in the internal components and eventually the pump will fail. The other disadvantage is that they are more costly in the market compared to the non-submersible pumps.
