What exactly is a Foul Pump Station?
In low gravity areas, foul pump stations, also known as lift stations, transport wastewater from one point (point A) to another point(point B).
When wastewater flows downhill, what happens when it needs to return to higher ground?
This is where a foul pump station comes in to help!
Foul pump station components
A typical foul pump station consists of a tank with an inlet, an outlet, and one or more electricity-powered pumps inside. A float switch activates the pump when sewage enters the pump station and reaches a certain level. The wastewater is then propelled by the pump to the next point of contact, such as a sewer or a treatment plant.
Large wastewater pump stations are equipped with a control panel that allows for manual operation during maintenance or repairs. Pumping stations normally operate on a single pump or set of pumps, but they will have backup pumps ready to take over if one of the pumps fails. This is referred to as built-in redundancy.
Pumping stations are the most efficient way of transporting wastewater. The size of the pump station and the power of the pumps will be determined by the volume and type of wastewater to be pumped, so let's look at some examples.
A Look inside Traditional Pump Stations
Older pump stations were frequently made up of a wet well and a separate, adjacent dry well that housed the pumps.
The wet well collects wastewater that flows by gravity. It is connected to the pumps inside the dry well. For two reasons, dry well pumping stations are no longer a popular option.
1.Access to underground spaces is restricted, making maintenance and repair work difficult and dangerous.
2.Flooding danger – a leaking pipe or a pump failure can fill the dry well with sewage, causing costly damage.
As a result, wet well pump stations and wet wells with integrated pumps have largely displaced traditional dry well pump stations. Submersible pumps are the pumps found inside a wet well, and we'll go over them in the following section.
What are Submersible pumps?
Submersible pumps, as the name implies, are submerged in wastewater.
A submersible pump's motor is carefully sealed to prevent liquid from entering and causing it to fail. Submersible pumps can be lifted to ground level using a chain and guide rail system, making maintenance and repairs much safer and easier than accessing pumps in a dry well.
Submersible pump or foul pump stations are used in a wide range of applications, from domestic and light commercial to municipal and industrial. The typical operational ranges of submersible pumps are listed below:
· The flow rate ranges from 20 to 28000 lpm.
· The horsepower ranges from 1 to 250 hp.
· The total head (pressure) ranges from 0.4 to 6 bars.
What are the pumps for Grinder systems?
It may be necessary for the foul pump station to be capable of handling solids in some applications. A grinder pump, which is commonly used in domestic sewage pumping applications, reduces solids in wastewater to create a fine slurry, which it then pumped to a septic tank or sewer. In a residential area, a single grinder pump station may serve several houses.
What are Packaged Pump Stations?
A packaged pump station is a self-contained system that houses all of the internal pipework inside a watertight, reinforced tank. Following the installation of the tank below ground, the submersible pump and control equipment are installed and connected to the power supply. The pump station is ready to use once the inlet and outlet pipes are connected.
Pumping thousands of litres of wastewater and sewage every day will inevitably result in internal wear and tear.
As a result, controls and alarms are critical pieces of equipment for foul pump stations. When the wastewater level exceeds a certain threshold, an alarm will sound to indicate a system failure. This is especially useful for large foul pump stations that require close supervision and regular checks.
