Difference between Sewage Pump and Sump Pump

Sewage pumps and sump pumps are utilised for pumping the water. They were used in homes and other areas. Both pumps are installed in the basement of the building, which has a tank for holding the water. Sewage pumps contain the alarm that will be triggered when the sewage pump detects the excess water, and the excess water will be transferred to another storage tank.

In order to send wastewater from a bathroom, kitchen, basement, or below- ground sewage basin to a septic tank or public sewer system, we need to use the sewage pump. On the other hand, a sump pump is used to prevent basement flooding, and remove water that has accumulated in a sump basin, which is normally found in a basement or crawl space.

Sump pumps are crucial for homes in areas with a high water table or those that are vulnerable to flooding or excessive rain. They can also be used in commercial structures to stop water damage and give the building owners peace of mind.

What is Sewage Pump?

A sewage pump is a tool or machine that is used to transport sewage and wastewater from one location to another. It is frequently found in residential or commercial properties where they use a septic tank instead of a municipal sewage system. In order to dispose of sewage properly, the pump is used to move it from the tank to a drain field.

A cylindrical tank with an inlet and an outlet, an impeller-driven motor, and a float switch are the parts of the sewage pump. The float switch activates the motor when the water level in the tank reaches a certain level.

When the impeller generates a water flow, it forces the sewage out of the tank and through the pipes. To fulfil different types of needs and capacities, the sewage pump is available in a wide range of sizes, powers, and materials. They can be powered by electricity, gas, or alternative energy sources, and they can be situated above ground or submerged.

A sewage pump is used for the pumping of waste material and water. In a conventional sewage pump, it can only pump small materials. Sewer ejectors and sewage grinder pumps are other names for it. Sewage pumps use gravity to pump the solid waste and other materials from houses and buildings.

Sewage pumps are available in different materials, which include cast iron, stainless steel, plastic, and bronze. Cast iron pumps are robust and long-lasting, but they may also be large and noisy. The stainless steel pumps are resistant to corrosion, even though they are more expensive. Although lightweight and inexpensive, plastic pumps can be less reliable. Pumps made of bronze provide an excellent balance between price and robustness.

What is Sump Pump?

The Sump pump contains a float switch that activates the pump when the water level in the sump basin rises to a specific level. The water is subsequently removed from the basement by the pump and dumped far from the building, generally into a nearby storm drain or dry well. The key role of the sump pump is to drain extra water that has built up in the sump basin and stop the basement from flooding.

The Sump pump consists of two main types and there are pedestal and submersible pumps. Pedestal Sump pump contain the impeller, which is in charge of pumping the water, below the motor, which is situated above the sump basin. The Submersible pumps have the engine inside the sump basin and are completely submerged in water.

Differences Between Sewage Pump and Sump Pump

The following table highlights the major differences between Sewage Pump and Sump Pump −


Sewage Pump

Sump Pump


Pumps the wastewater and bathroom drains

Prevents from floods and rains which causes damage to house and buildings

Powered By

It runs on electricity

It runs on electricity and has a backup power supply


It pumps sewage waste

It pumps only liquid

Water Source

Dirty water, like solids and other debris

Clean water, like ground or rain water


The water needs to be pumped out frequently

The float switch will be activated when the water level reaches a certain level


It directs the water to a sewer main or septic tank

It directs the water to a drainage area or dry well that is outside the buildings


In conclusion, the sump pump is intended to remove water that has accumulated in a sump pit, generally in a basement. On the other hand, the sewage pump is used to manage the waste and sewage water. Sump pumps are smaller and more compact, but the sewage pumps are larger and more powerful. A sump pump doesn’t need a vent system, whereas sewage pump needs a vent system.
