Before we dive into the details of septic pumps, let’s first understand the basics of a septic system. A septic system is an underground wastewater treatment system that is commonly used in rural areas. It consists of a septic tank and a drain field. The septic tank is where all the wastewater from the house goes. Inside the tank, solids settle to the bottom, and bacteria breaks down the organic matter. The remaining liquid effluent flows out of the tank and into the drain field, where it is further treated by the soil.

Septic Tank Pump To Drain Field: What Is A Drain Field?

A drain field, also known as a leach field or absorption field, is an important component of a septic system. It is a network of underground pipes or chambers that allow the effluent (partially treated wastewater) from a septic tank to be released into the soil for further treatment and disposal.

The effluent that enters the drain field is typically a combination of water, organic matter, and bacteria. As the effluent enters the soil, it is treated by microbes in the soil, which break down the organic matter and filter out harmful pathogens and pollutants. The treated effluent then becomes groundwater, which can be safely reabsorbed into the environment.

A properly designed and maintained drain field is crucial for the effective and safe disposal of wastewater from a septic system. If the drain field becomes clogged or damaged, it can lead to backups, odors, and environmental contamination.

Septic Tank Pump To Drain Field: What Is A Septic Pump?

A septic pump is an essential component of a septic system. It is a mechanical device that moves effluent from the septic tank to the drain field. Septic pumps are commonly used in situations where the drain field is located uphill from the septic tank, or the drain field is located far away from the tank. Septic pumps can also be used to move wastewater from multiple septic tanks to a central drain field.

How Does A Septic Pump Work?

A septic pump typically consists of a pump, a float switch, and a control panel. The pump is located in a separate chamber of the septic tank and is connected to a discharge pipe that leads to the drain field. The float switch is located inside the pump chamber and is responsible for turning the pump on and off as the wastewater level in the chamber rises and falls. The control panel is typically located outside the septic tank and is used to monitor and control the pump.

When effluent leaves the septic tank, it flows into the pump chamber. As the effluent level in the chamber rises, the float switch activates the pump, which pumps the effluent through the discharge pipe and into the drain field. Once the wastewater level in the chamber falls below a certain level, the float switch turns the pump off.

Do You Need A Septic Pump?

Septic tanks with pumps? If you’re wondering whether you need a septic pump or not, the answer depends on the location and elevation of your drain field. In general, a septic pump is unnecessary if the effluent can flow through gravity at a rate of two feet per second. This is the ideal situation where wastewater flows downhill from the house to the septic tank and then to the drain field, without the need for any additional assistance.

However, in some cases, the drain field may be elevated or raised, which makes it impossible for the wastewater to flow through gravity alone. This is where a septic pump becomes a necessity. Septic pumps are used to pump wastewater from the septic tank to the drain field, even if the drain field is located uphill from the septic tank. In these situations, a septic pump is essential for ensuring proper and efficient wastewater treatment.

One example of a system that requires a septic pump is a septic mound system. A septic mound system is a type of septic system that is used in areas with poor soil conditions or where the water table is high. It involves creating a raised bed of soil on top of the natural soil, which provides additional filtration and treatment of the wastewater before it is released into the environment. In a septic mound system, the drain field is elevated, which means that a septic pump is necessary to move the wastewater from the septic tank to the drain field.

Importance Of Maintaining A Septic Pump

Like any mechanical device, septic pumps require regular maintenance to ensure they function properly. A malfunctioning septic pump can lead to backups, clogs, and other problems that can be costly and time-consuming to fix. It is recommended that septic pumps be inspected and serviced at least once a year to ensure they are working correctly. Regular maintenance can also help extend the lifespan of your septic pump and prevent the need for costly repairs or replacements.

Septic Tank Pump To Drain Field: FAQs

Here is a list of the most common frequently asked questions about Septic Tank Pump To Drain Field:

Can you pump out a septic drain field?

While it may be tempting to try to pump out a flooded or saturated drain field by back-pumping the water, this is not an effective solution and can actually be harmful to your septic system. When a drain field becomes flooded or saturated, it is a sign of a larger issue with the septic system, such as a malfunctioning septic tank or clogged drain pipes. Simply pumping out the water from the drain field does not address the root cause of the problem and can lead to further damage to the drain field.

What is the best way to unclog a septic drain field?

If you’re experiencing problems with a clogged septic drain field, there are a few steps you can take to try to clear the blockage. The first step is to use a pressurized sewer jetter to clear clogs in the drain field pipes. A pressurized sewer jetter is a powerful tool that uses high-pressure water to blast away obstructions and debris in the pipes. This can be an effective way to clear minor blockages in the drain field and restore proper flow of wastewater.

However, if the pressurized sewer jetter doesn’t work, it’s likely that the clog is due to tree roots that have grown into the pipes. In this scenario, a mechanical auger is the best option to clear the tree root clogs. A mechanical auger is a tool that uses a rotating cable to break up and remove the tree roots from the pipes. This is a more aggressive approach, but it’s often necessary to fully clear the blockage and restore proper function to the drain field.

How do I know if my Drainfield is clogged?

If you suspect that your septic drain field may be clogged, there are several tell-tale signs that you can look for. The first and most obvious sign is a foul odor emanating from the drain field area.

Another common sign of a clogged drain field is a gurgling sound coming from your toilet or drains. This sound is caused by air bubbles that are trapped in the plumbing system as wastewater is unable to flow freely through the drain field.

You may also notice pools of water around the drain field area, which can be a sign that the drain field is not functioning properly and is unable to absorb and process the effluent from your septic system.

Finally, another sign of a clogged drain field is that the grass around the septic tank and drain field may be noticeably greener compared to the rest of your yard. This is because the excess nutrients and moisture from the septic system are being absorbed by the grass and causing it to grow more vigorously.


In conclusion, a pump for septic tank is an essential component of a septic system that moves effluent from the septic tank to the drain field. It is a mechanical device that requires regular maintenance to ensure it functions correctly. Understanding how a septic pump works and its importance in maintaining a healthy septic system can help you make informed decisions regarding your plumbing system.
