A Septic Tank Pump System is an essential part of onsite sewage treatment service. In normal operation, effluent from the septic tank flows into the pump chamber, which is equipped with a pump that pushes the effluent out to the drain field. The pump is typically activated by a float switch, which turns the pump on when the effluent reaches a predetermined level and turns it off when the level drops.

Types Of Pump Systems

There are several types of pump systems used in onsite sewage water services. The most common types include:

  1. Effluent pumps: These pumps are used to pump effluent from a septic tank to a drain field or mound.
  2. Sewage ejector pumps: These pumps are used to pump sewage from a basement or below-grade bathroom up to the septic tank or sewer line.
  3. Grinder pumps: These pumps are used to grind sewage into a slurry before pumping it to a septic tank or sewer line.
  4. High-head pumps: These pumps are used when there is a significant elevation difference between the septic tank and the drain field or mound.
  5. Low-pressure dosing pumps: These pumps are used to evenly distribute effluent over a drain field or mound.

Septic Tank Pump System: Design Considerations

When designing a pump system, several factors need to be considered to ensure optimal performance and longevity. These factors include:

  1. Pump capacity: The pump must be sized to handle the peak daily flow of the system. If the pump is too small, it will not be able to keep up with the flow, leading to backups and other problems. If the pump is too large, it will cycle on and off too frequently, which can lead to premature failure.
  2. Pump type: The type of pump used in the system will depend on the application and the site conditions. Effluent pumps are generally the most common type of pump used, but other types may be required depending on the situation.
  3. Float switch type: There are several types of float switches available, including tethered, vertical, and electronic. The type of switch used will depend on the application and the pump type.
  4. Electrical requirements: Pump systems require electrical power to operate. The electrical requirements will depend on the pump type and the location of the system.
  5. Access and maintenance: Pump systems should be designed to allow for easy access and maintenance. This includes providing a service panel, access hatch, and other features to make servicing the system as easy as possible.

Septic Tank Pump System: Installation And Maintenance

Proper installation and maintenance are essential to ensuring optimal performance and longevity of a pump system. Some key considerations include:

  1. Proper pump installation: The pump should be installed level and securely anchored to prevent movement during operation.
  2. Float switch installation: The float switch should be installed at the correct level to ensure proper activation and deactivation of the pump.
  3. Electrical connections: Electrical connections should be made according to local electrical codes and the manufacturer’s instructions.
  4. A pump for septic tank is an important component of a septic system that is responsible for transporting wastewater from the septic tank to the drain field. To ensure that the septic pump operates efficiently and safely, it is necessary to have a dedicated circuit for it. A dedicated circuit is a specific electrical circuit that is designed to supply power to a single appliance or device. In the case of a septic pump, having a dedicated circuit means that it has its own electrical wiring, circuit breaker, and outlet. The reason why a septic pump needs a dedicated circuit is to prevent overloading of the electrical system in the house. If the septic pump is connected to a circuit that is already powering other appliances or devices, it can cause the circuit to overload, resulting in power outages or damage to the electrical system. In addition, a dedicated circuit ensures that the septic pump has a stable and consistent source of power. This is important because fluctuations in power can cause the septic pump to malfunction, which can lead to costly repairs or replacements.
  5. Regular maintenance: Pump systems should be serviced regularly to ensure optimal performance. This includes inspecting and cleaning the pump and float switch, checking electrical connections, and monitoring system operation.

Septic Tank Pump System: FAQs

Here are some frequently asked questions about septic tank pump system:

How long should a septic pump last?

The lifespan of a septic pump can vary depending on factors such as usage, maintenance, and the quality of the pump. In general, a septic pump should last between 5-7 years with proper maintenance and care.

However, if the pump is subjected to heavy usage or is not properly maintained, it may fail sooner. Regular inspections and maintenance can help ensure that your septic pump operates efficiently and prolong its lifespan.

If you notice any signs of trouble with your septic pump, such as unusual noises, slow drainage, or sewage backup, it’s important to have it inspected and repaired by a professional as soon as possible to prevent further damage to your septic system.

How do I know if my septic pump has failed?

There are several signs that your septic pump may have failed, including:

  1. Slow drainage: If your sinks, toilets, and showers are draining slowly or not at all, it could be a sign that your septic pump has failed.
  2. Unusual noises: If you hear unusual noises coming from your septic tank, such as gurgling or bubbling sounds, it may indicate that your pump is not working properly.
  3. Sewage backup: If sewage backs up into your home or yard, it is a clear sign that your septic pump has failed and requires immediate attention.
  4. Foul odors: If you notice a strong, foul odor around your septic tank or in your home, it could be a sign that your septic pump has failed and waste is not being properly removed from the tank.
  5. Septic Tank Alarm: Many septic pump systems have an alarm that alerts you if the pump is not functioning properly. If the alarm goes off, it is a sign that your pump has failed and needs to be repaired or replaced.

If you notice any of these signs, it is important to have your septic system inspected by a professional as soon as possible. Delaying repairs can lead to further damage and costly repairs.

Septic Tanks With Pumps

Conventional or traditional septic systems rely on gravity to move effluent from the septic tank to the drain field. However, in some cases, the drain field may be located at an elevation that is higher than the septic tank, or the drain field may be located too far away from the septic tank for gravity to effectively move the effluent.

In these situations, septic pumps can be used to move the effluent to an elevated or raised drain field. Septic pumps are typically installed in the septic tank or in a separate pump chamber and are designed to move the effluent through pipes to the drain field.


In conclusion, pump systems are an essential part of onsite sewage water services. Proper design, installation, and maintenance are critical to ensuring optimal performance and longevity of the system. Understanding the different types of pump systems available and the factors that need to be considered when designing and installing a system is essential.
