Vacuum Station

Finally, the sewage reaches the vacuum station, which is the third element of the system.

The main items of equipment within the vacuum station are vacuum pumps, a collection vessel, sewage discharge pumps and an electrical control panel.

The vacuum pumps are connected to the collection vessel via pipework and they create the vacuum pressure within both the vessel and the connecting vacuum sewers.

The arriving sewage is initially stored in the collection vessel which acts as the wet sump normally found within a conventional gravity pumping station.

Rising sewage levels within this collection vessel are detected by level probes which initiate the operation of sewage discharge pumps connected via pipework to the vessel.

These pumps remove the collected sewage from within the vessel and forward it to the local sewage treatment plant or nearby main sewer.
