What is the difference between sewage pumping station and sewage lifting pumping station

The sewage pumping station is the inlet pumping station of the sewage treatment plant, and its function is to pump up the sewage from the confluence of the underground sewage pipe network of the city to the pool on the ground of the sewage plant for treatment.

The sewage conveyance process, due to the long distance, sewage pipes in the ground there is a great depth, in order to reduce the subsequent conveyance of pipeline depth, in the sewage conveyance of the midway set up pumping station, sewage is lifted and then sent to a more distant place through the sewage pipe (sewage treatment plant or the next sewage lifting pumping station), so sewage lifting pumping station is just a transfer station.

Sometimes both types of pumping stations are needed, but the principle of the role of the sewage pumping station itself is not different, just in a different location.
