Can I eliminate the pump in my septic system?
No, you can't eliminate the pump. The drain field is higher than the septic tank. 

If you have a mound system (elevated drainfield) or a pressurized sewer system, then the pump has to lift the effluent (outflow from the septic tank) up to the drain field level or pump against the pressure of a pressurized utility system.

If you eliminate the pump then sewage will eventually back up into your house. Yuck!

If the pump keeps tripping the breaker and you have replaced the breaker then the pump is probably malfunctioning and needs repair or replacement.

Good luck!
