A packaged pumping station provides an efficient and economical way of installing a drainage system that can be used to remove foul water, surface water and sewage in areas of low gravity or where connection to the main drain is difficult such as home extensions, garden rooms, outbuildings and remote properties.
A Packaged Pumping Station is a mechanical device installed in a sewer or water system or other liquid-carrying pipeline to move a liquid to a higher level, usually consisting of one or more submersible pumps installed in a tank. They are sometimes referred to as ‘sump pumps’, ‘sewage systems’ or ‘pump stations.’ They are usually self-contained units that are built to order off-site and delivered ready to install either below or above ground.
Sewer Systems and Pumping Stations
Sewer pipes generally rely on gravity to move waste water, allowing it to flow slowly downhill until it reaches a low point, then pumping, or “lift” stations sited at the low point and push the waste water back uphill to a high point where gravity can once again take over the process. The pump station discharge pipe is a continuous main through which sewage or effluent is pumped to a final destination.
A pumping station is usually an underground structure that foul, surface water or sewage is discharged into. Types of pumping station vary but in smaller systems the sewage is discharged into a wet well which also houses submersible pumps which then pump the sewage to its destination. In a larger station there may be a separate dry well, adjacent to the wet well, which houses the pumps. On some pumping stations the pumps may be housed above ground near the wet well.
A package pumping station is an integrated system, manufactured from strong, impact-resistant polyethylene or GRP (glass-reinforced plastic). The unit is supplied with fitted internal pipework, ready for installation below (or above) ground, after which submersible pumps and control equipment are fitted. Features may include controls for fully automatic operation; a high-level alarm that operates in the event of pump failure; and possibly a guide-rail/auto-coupling/pedestal system, to permit easy removal of pumps for maintenance or repair.
Compared to the conventional brick or concrete well and separate pump system, a packaged pumping system offers reduced costs and time involved with civil work and site labour.
Properties with pumping stations
The Government has introduced new rules that simplify the way septic tanks and small sewage treatment plants are regulated in England, as of January 2016 septic tanks and small sewage treatment plants no longer need to be registered in order for a property to be sold.
However, owners of properties with septic tanks and small sewage treatment plants are still responsible for meeting ‘general binding rules‘; all private pumping stations and septic systems should be properly maintained and must not cause pollution.
Submersible Pumps and Pumping Stations
The use of submersible pumps became popular in the early 1960s, when a guide-rail system was developed to lift the submersible pump out of the pump station for repair, and ended the dirty and sometimes dangerous task of sending people into the sewage or wet pit.
Submersible pumps are found in many applications, including drainage, sewage pumping, general industrial pumping and slurry pumping. A submersible pump is a pump which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in the fluid to be pumped. The advantage of this type of pump is that it can provide a significant lifting force as it does not rely on external air pressure to lift the fluid.
