AboveGround Sewage Pump Stations

Above ground pump stations are ideal where excavation is difficult or costly — high water tables, rocky ground, or restricted access for digging plant. They're also useful for temporary installations, basement conversions, or extensions where the invert level of the drainage is above the main sewer connection. Because there's no groundworks involved, they're quicker and cheaper to install than a sunken chamber.

Sizing depends on the number of occupants or bedrooms the property serves and the daily flow of wastewater being pumped, with domestic properties typically needing a smaller single-pump unit and larger households or commercial premises requiring higher-capacity or twin-pump systems up to 3001 litres. You should also factor in the pumping distance and head height (vertical lift) required to reach the discharge point, as this affects pump selection. If you're unsure, it's worth speaking to us with your property details before ordering.

A twin pump station has two pumps that alternate use, which reduces wear on each unit and extends the overall lifespan of the system. If one pump fails, the second automatically takes over, giving you built-in redundancy and avoiding an emergency call-out. Twin systems are commonly specified for commercial properties, larger households, or anywhere failure would cause significant disruption.

Most domestic installations fall under permitted development, but you'll still need to comply with Building Regulations Part H, which covers drainage and waste disposal, and Building Control should be notified of the installation. If the discharge connects to a public sewer, you'll also need approval from your local water company under the Water Industry Act. It's always worth checking with your local authority before installation, particularly for commercial sites.

Our above ground pump stations are typically constructed from durable, corrosion-resistant polyethylene or GRP (fibreglass), both of which are unaffected by rain, frost, or UV exposure over time. This makes them suitable for permanent outdoor installation in exposed or coastal locations without the risk of rusting or degrading like older steel units. They're also designed to be low-maintenance, so once installed and commissioned, they need minimal ongoing attention.

Yes, many above ground pump stations are compact enough to be sited indoors in a garage, utility room, or dedicated plant room, provided there's adequate ventilation and access for maintenance and alarm monitoring. Indoor installation protects the unit from weather extremes and can simplify pipework runs where the property layout allows it. Just ensure there's a suitable power supply nearby and that any odour or noise from operation won't cause a nuisance in an occupied space.
