No. A sump pump is installed to pump out any water that has entered a basement before it starts flooding the basement floor. Since good septic tank maintenance requires not overloading your septic system, you would want to avoid running excessive amounts of water through the system. The water flow from a sump pump should go out of the house through a discharge pipe that carries the water far away from the house to a field tile or storm sewer. Do not discharge the water onto a septic system drain field.
