What Is a Wastewater Ejector Pump

A sewage ejector pump is designed to move wastewater uphill from plumbing fixtures, such as bathrooms or laundry rooms, that are located below the level of the main sewer or septic line.

Normally, sewage and wastewater flow downhill by gravity to the main sewer or septic system. However, when wastewater needs to be pushed upward, a sewage ejector pump is necessary to ensure proper drainage.

Why You May Need a Sewage Ejector Pump

You need a sewage ejector pump if your home has a basement or below-grade (below ground level) bathroom or laundry room. If your sewer line slopes upward from these fixtures, a pump is required to move wastewater uphill. And if the line slopes downward, a pump is typically not necessary.

Sewage ejector pumps are also common in homes with septic drain fields. In rural areas, the septic drainage field or holding tank is often located above the level of the bathroom or laundry room, which makes a pump essential for proper wastewater removal.

How Sewage Ejector Pumps Work

Sewage ejector pumps are installed in a sump basin located below grade. Here’s how the system operates when wastewater is discharged from a toilet or laundry room:

  1. Wastewater flows by gravity into the sump basin.
  2. The basin gradually fills with wastewater.
  3. As the water level rises, a float connected to the ejector pump also rises.
  4. When the float reaches a preset level, it activates the pump.
  5. The pump pushes wastewater upward to the main sewer or septic line.
  6. As the basin empties, the float lowers.
  7. When the float drops to a specific level, the pump shuts off automatically.

This automated process efficiently removes wastewater from plumbing fixtures below ground level. Unlike traditional gravity sewage systems that rely on downhill pipes or septic systems that depend on drainage fields without mechanical help, ejector pumps move wastewater uphill or across flat areas effectively.
