The Difference between Sewage, Sump, Drainage Pumps & More

This page will explain the difference between Sump Pumps, Sewage Pumps, Drainage Pumps, Sewage Grinder Pumps, Sewage Cutter Pumps, Sewage Ejector Pumps & Pump Stations.  It will also show you what pumps to use for each situation.  This is very helpful when deciding which submersible pump to buy.

SUMP PUMPS

Sump pumps are designed to pump clean or dirty water such as surface or ground water that leak into a building. Sump pumps only have to pump water, but can handle small particles (not large particle sizes).

If there are some solids then a sewage pump can usually do the job of a sump pump.

What separates sump pumps from sewage pumps is their inability to handle solids or larger particle sizes.

A sump pump is normally installed in a pit at the low end of a basement or crawl space floor.

There are many ways that these pumps can be used for draining water.

1 – Water flows from your house via the perimeter drains of a basement waterproofing system, funneling into the basin or because of rain or natural ground water, if the basement is below the water table level.

2 – Basement flooding is another use for a sump pump.

This water flows to the tank or pit. As the tank/pit fills, it causes the float switch to stand up vertically, triggering the pump to turn on and empty the tank until the float switch lays horizontal again (floating on top of the water) which automatically switches the pump off.

A discharge pipe is attached to the outlet of the pump which pushes the drained fluid up and away from the tank/pit. Sump pumps send water away from a house to any place where it is no longer problematic, such as a storm drain or sanity sewer.

You can use sump pumps to drain or pump fluids from many situations. When selecting a pump, you need to look at the particle size that the pump can handle. I have clearly listed the particle size that each model can handle.

The next thing to look at when selecting a pump is the total head that the pump can handle. As the head increases, the flow lessens. The flows in LPM (Liters Per Minute) listed is the maximum flow the pump will deliver at the lowest head.

Calculate the head by adding the static head plus the pipe friction loss and the discharge pressure. I can help you work this out if you email me your pumping situation details.

Another thing to look at is the flow required. Most set ups don’t need a large flow, but if you need to pump out a large amount of water quickly then you need to look at how many Liters Per Minute (LPM) the pump will handle.

SEWAGE PUMPS

Sewage Pumps or Effluent Pumps are designed to pump dirty water and sewage (which has overflowed from septic tank), from the grey water tank / pump-out-pit and not actual RAW SEWAGE.

What separates sewage pumps from ordinary sump pumps / drainage pumps is their ability to handle larger solids.They can usually handle larger particles and solids up to 35mm (sometimes larger) that overflow from the septic tank.

There are many ways that these pumps can be used for draining dirty water. The basic way the pump works on effluent is as follows: Raw sewage and grey water flow from your house downhill to the septic tank. From the septic tank, the fluids overflow into the grey water tank/pump-out-pit. The sewage pump sits at the bottom of this tank/pit. As the tank/pit fills, it causes the float switch to stand up vertically, triggering the pump to turn on and empty the tank until the float switch lays horizontal again (floating on top of the fluid) which automatically switches the pump off.

A discharge pipe is attached to the outlet of the pump which pushes the drained fluid up and away from the tank/pit.

You can use these sewage pumps to drain or pump fluids from many situations. When selecting a pump, you need to look at the particle size that the pump can handle. If you are pumping effluent from a septic tank, then a pump that can handle larger particle sizes would be better. I have clearly listed the particle size that each model can handle.

The next thing to look at when selecting a pump is the total head that the pump can handle. As the head increases, the flow lessens. The flows in LPM (Liters Per Minute) listed is the maximum flow the pump will deliver at the lowest head.

Calculate the head by adding the static head plus the pipe friction loss and the discharge pressure. I can help you work this out if you email me your pumping situation details.

DRAINAGE PUMPS

Drainage pumps are usually used for draining clean water only, so the particle sizes are smaller than that of a sewage pump or sump pump. You can use drainage pumps to drain or pump fluids from many situations.

There is even a Puddle Sucker Pump that will drain water down to a level of 2mm.

These pumps can be used with an automatic float switch as in the image or manually. If there is not a lot of room in the pit or tank, then they can be used with a controller.

The water flows to the tank or pit. As the tank/pit fills, it causes the float switch to stand up vertically, triggering the pump to turn on and empty the tank until the float switch lays horizontal again (floating on top of the water) which automatically switches the pump off.

A discharge pipe is attached to the outlet of the pump which pushes the drained fluid up and away from the tank/pit. Drainage pumps send water away to any place where it is no longer problematic, such as a storm drain or sanity sewer.

SEWAGE GRINDER PUMP

To pump RAW SEWAGE use a Sewage Grinder Pump. If it is being used for a public venue then it would be best to use a Grinder Pump and not a Cutter Pump.

Waste from water-using household appliances (toilets, bathtubs, washing machines, etc) flows through the home’s pipes into the grinder pump’s holding tank. Once the wastewater inside the tank reaches a certain level, the pump will turn on, grind the waste into a fine slurry, and pump it to the septic tank or sewer system.

Sewage Grinder Pumps can be used with an automatic float switch, with a controller or manually. If there is not a lot of room in the pit or tank, then they are usually used with a controller.

Automatic Submersible Sewage Cutter Pumps

SEWAGE CUTTER PUMP

To pump RAW SEWAGE use a Sewage Cutter Pump. A sewage cutter pump is similar to the grinder pump but can’t handle everything that may get flushed down a toilet. It can only handle raw sewage and toilet paper. This is why a cutter pump can be used for a household situation where you know what is going into the tank. But if it is a public venue, a grinder pump is needed.

Waste from water-using household appliances (toilets, bathtubs, washing machines, etc) flows through the home’s pipes into the grinder pump’s holding tank. Once the wastewater inside the tank reaches a certain level, the pump will turn on, grind the waste into a fine slurry, and pump it to the septic tank or sewer system.

SEWAGE EJECTOR PUMP

NOT ENOUGH FALL FROM HOUSE TO SEPTIC?

If you are pumping sewage effluent and grey water from a house to your septic tank and there is not enough fall for the fluids to gravity feed freely into your septic tank, then a small pumping system (which includes a small tank with a sewage pump, usually a grinder pump) may be required to store the fluids under the house and pump them uphill to reach the septic.

These pumps can be automatic (with a float switch or controller) or manual.

Sewage Ejector Pumps are designed to remove sewage from a building where plumbing fixtures and their drains are lower than the building sewer line and/or septic tank.

Most systems need to be custom made as tank sizes and pump sizes will vary depending on how many utilities such as toilets, showers, basins, etc are feeding the tank and what flow is required to empty the tank.

When selecting a pump, you need to look at the total head that the pump can handle. As the head increases, the flow lessens. The flows in LPM (Liters Per Minute) listed is the maximum flow the pump will deliver at the lowest head.

Calculate the head by adding the static head plus the pipe friction loss and the discharge pressure. I can help you work this out if you email me your pumping situation details.

Another thing to look at is the flow required. Most set ups don’t need a large flow, but if you need to pump out a large amount of liquids quickly then you need to look at how many Liters Per Minute (LPM) the pump will handle.
