Understanding the Pump Tank in a Septic System

When discussing septic systems, one critical component that often comes into play is the pump tank. This element is vital for ensuring that wastewater flows efficiently from the septic tank to the drain field. Understanding the function, installation, and maintenance of pump tanks can help homeowners ensure their septic systems operate smoothly and efficiently.

What is a Pump Tank?

A pump tank is a specialized container used in septic systems to aid in the distribution of wastewater. Unlike traditional gravity-fed septic systems, where wastewater flows simply due to gravity from the septic tank to the drain field, a pump tank is necessary in situations where the drain field is situated at a higher elevation than the septic tank. The pump tank contains a submersible pump that activates when the wastewater reaches a certain level. It then pumps the effluent to the drain field, ensuring adequate dispersion and reducing the risk of system failures.

The Role of the Pump Tank in Wastewater Management

The pump tank plays a crucial role in managing the treatment of wastewater. Here are the main functions

1. Efficient Distribution It ensures an even distribution of effluent across the drain field, preventing localized over-saturation, which can lead to system failure.

2. Pressure Regulation By creating pressure, it allows wastewater to flow through various types of filtration systems, accommodating different landscaping elevations.

3. Filtration and Settling Before wastewater is pumped, the pump tank usually incorporates a settling area where heavier solids can settle out, preventing them from clogging the pump and the drain field.

Installation of a Pump Tank

1. Site Assessment A professional must assess the land to determine the appropriate location for the septic system and pump tank, including considerations for soil type, percolation rate, and proximity to water sources.

2. Choosing the Right Size The pump tank should be sized appropriately based on household wastewater output and the specific needs of the drain field. General recommendations suggest that a pump tank should hold at least 24 to 36 hours of wastewater flow.

3. Digging the Pit The area for the pump tank must be excavated to accommodate the size of the tank and allow for proper landscaping and drainage.

4. Tank Selection Tanks are typically made from concrete, fiberglass, or plastic, each having its advantages in durability and maintenance.

5. Installation of the Pump The chosen submersible pump is installed in the tank along with the necessary piping and electrical connections.

Maintenance Tips

To ensure the longevity and functionality of a pump tank, regular maintenance is required

- Regular Inspections Check the pump system periodically for any signs of malfunction or wear. Regular inspections can prevent costly repairs down the line.

- Monitor Tank Levels Keep an eye on the tank levels to ensure that the pump activates and deactivates properly. A malfunction can lead to overflows or back-ups.

- Keep It Clear Ensure that nothing obstructs the intake or discharge lines of the pump. Avoid flushing inappropriate items down the toilet, as they can cause blockages.

- Professional Servicing Schedule regular professional servicing of the septic system, which should include the pump tank. A qualified technician should check the pump, control floats, alarms, and any other components.

Conclusion

In summary, the pump tank is an essential component of many septic systems, particularly in areas with challenging terrain. Understanding its role, proper installation, and the importance of maintenance can significantly contribute to the effective operation of a septic system. For homeowners, investing in quality components and staying informed about upkeep can lead to a long-lasting and efficient wastewater management solution. Regular monitoring and professional assessments will help maintain the health of your septic system and avoid costly repairs in the future.
