Our video at right demonstrates the operation of a septic tank pump system alarm. More videos on septic system maintenance are at SEPTIC VIDEOS.

Septic alarms indicate when the septic tank pump is not operating. Repair is needed promptly.

Advice is given for septic tank effluent or sewage pump selection and use. Septic pumps used for pumping air in aeration systems and septic pumps used to move effluent in a drip dispersion system are discussed under the appropriate septic system type which are outlined at DESIGN ALTERNATIVES.

What are Septic Pumps, Effluent Pumps, & Sump Pumps

Readers have asked the difference between a sump pump, simplex and duplex sump pumps, a septic effluent pump, a sewage grinder pump, and an effluent pump. Here we discuss the various types of pumps and their purchase, installation, inspection, and maintenance.

What is a Sump Pump?

Sump pumps, which we discuss on this page, are designed to remove unwanted water, such as surface or ground water that leak into a building. Sump pumps only have to pump water, never solids.

A sump pump is normally installed in a pit at the low end of a basement or crawl space floor.

In a bad building water entry situation water runs across the basement/crawl space floor into the sump pit where it is pumped away (after already wetting the building and inviting a mold contamination problem). This condition pertains when water is entering a building through foundation walls, often because the roof drainage or surface runoff are directed right against the building foundation itself. Keeping gutters and leaders working and correcting outside drainage errors are critial in keeping water out of a building. Doesn't it make more sense to prevent water from coming into a building than to let it in and then pump it out?

In a good situation, openings in the sides and bottom of the sump pit, or an under-floor drainage system direct subsurface water into the sump pit before the ground water level rises enough to send water into the building. Over several years of operation, and partly by pumping a little soil silt as it operates, a sump pump may actually improve the flow of under-floor water into the sump pit, thus reducing building water entry.

What is a Septic Pump, Sewage Pump, or Grinder Pump? What are the Types of Septic Pumps?

Septic pumps, sewage pumps, or sewage ejector pumps, which we discuss beginning at Sewage Ejector Pump Grinder Pump, are designed to remove sewage from a building where plumbing fixtures and their drains are lower than the building sewer line and/or septic tank.

Septic pumps have to move solids, either by being able to pass large solid objects through the pump without clogging, or by grinding the solids into fine debris.

Municipal lift stations, duplex sewage pumps, septic alarms, grinder pumps, submersible pumps, are discussed in more detail in this article.

What is a Septic Effluent Pump?

Septic effluent pumps are used to move clarified septic effluent out of a pumping chamber to a drainfield. Septic effluent pumps do not have to move solids, but are built to standards of durability and duty cycle more demanding than a typical sump pump used to remove ground water from a building. Typical examples of applications where septic effluent pumps are used include raised bed, mound, or sand-bed filtration septic systems in which the absorption bed is located higher than the septic tank. In these installations septic efflent is pumped from a final chamber in the septic tank or from a second effluent chamber up to the absorption system. In a pinch we've seen people use Sump Pumps for this application but that is not a durable nor a recommended solution.

Be Sure to Select the Proper Septic or Sump Pump Type

The distinction among these pump types is important when installing or repairing a septic system that uses pumps since choosing the wrong pump can mean a short operating life for the pump, an unreliable septic system, and unnecessary expense. In addition to explaining these different septic pump types, in this artile we also describe a community sewage pumping station and septic pump alarms as well as the inspection and installation details for this equipment.

Beware, there may be some confusion, depending on with whom you speak, because people don't always use just the right terms for construction or septic system parts - and the right sewage pump term, or right septic handling product versus the wrong one can be an important distinction.
