A pumping station is an underground or partially buried chamber containing one or more submersible pumps that lift foul or surface water from low-lying areas into a higher sewer or treatment system. They are widely used in basement flats, properties below the level of the public sewer and on new developments where gravity drainage is not feasible. UK installations follow Building Regulations Part H1 and BS EN 752 and usually include twin pumps for duty and standby, level controls and a high level alarm. Regular maintenance is essential to keep pumps free from rags, wipes and grease, which are a frequent cause of failure. Older Victorian London basements often need retrofitted pumping stations when converted to habitable rooms, particularly where toilets and basins are added below sewer level.
