What Type of Septic Pump or Sewage Pump Should I Buy?

Municipal Sewage pump motors on the ground at a site of frequent pump failure (C) Daniel Friedman

The type of sewage pump you need depends on how it will be used.

The pumps at left may have been a misapplication for this municipal lift station ,which may explain why we found these discarded units on the site.

Septic pump systems vary by these parameters:

  • Grinder vs. ejector pump:

    in how they treat the waste. Don't use a simple ejector pump if the pump has to handle solid waste.

    For handling sewage , wastewater that contains solids such as toilet paper and feces, you need a grinder pump or a macerating grinder pump or a vortex type sewage pump.

    See details at SEPTIC / SEWAGE PUMP TYPES
  • Lift capacity or "head" that the pump has to handle:

    by how many feet of elevation does the waste need to be raised to reach the build.

    "Head" is the term used to describe the height in feet that a column of wastewater needs to be raised, and is expressed in feet of lift.

    A "ten foot head" means that the pump has to be powerful enough to lift the column of waste water ten feet vertical distance.
  • Total wastewater system capacity needed:

    how many toilets and other fixtures is the pump serving.

    A basement bath including a shower, sink, and toilet, uses a small pre-packaged low-capacity septic grinder pump that may be just 1/3 hp.

    While in a home where all of the wastewater needs to be moved from a common pumping point to a higher-elevation sewer line, an higher capacity multi-horsepower pump needs to be used (and probably should be installed duplexed with a pair of pumps.)
  • Size of solids in the wastewater

     that need to be removed: larger solids are handled by larger grinder pumps. A pump with a four-inch impeller housing and impeller will typically be able to handle solids up to 3" in diameter without clogging.
  • Water temperature:

    most sewage pumps are designed to operate at a maximum temperature of 180 deg F. So if a restaurant were installing a pumping station that had to handle near-boiling water, say from a commercial dishwasher or an asian fast-food cooking line, special equipment may be needed.

Duplex septic pump installation (C) InspectApedia.com DJF

  • Septic / Sewage Pump Duty Cycle: 

    a community pumping station or a sewage pumping system serving a multi-family home needs to be able to run more frequently to handle the much higher wastewater load than that from a single family home.
  • Reliability requirements doe your sewagfe pump

    while single-pump systems are often installed to support an extra basement bathroom, where a sewage pump is handling an entire home or larger facility, duplex septic pumping systems (shown in the photo ) are preferable for their greater reliability.

    Remember that in a power outage your pump system will not work unless you've provided backup power.

  • Vertically-suspended sewage grinder pumps and closely-coupled submersible sewage grinder pumps 

    are further distinguished and described in more detail

    at SEWAGE PUMPING STATIONS.

Septic pump manufacturers provide a pump selection and sizing table

that is used to guide the installer in selecting the proper pump. We've seen sewage handling systems where the wrong type or wrong capacity of pump was installed, sometimes as an attempt to "save money."

Two types of sewage pumps are used in residential applications, sewage grinder pumps or sewage ejectors pumps, and non-clogging sewage ejector pumps.

We describe these at Septic Pump DUPLEX SYSTEM DESIGNS or select a topic from the closely-related articles below, or see the complete ARTICLE INDEX.

...

Parameters used to Select the Proper Septic, Sewage, or Sump Pump Type

Sewage pump (C) Daniel Friedman

The distinction among sewage pumps or septic 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.

The following are the basic paramaters you need to know before choosing a sewage, sewage grinder, effluent or septic pump or sump pump type, capacity, and model or design.

  • Wastewater flow rate or volume

    in US or Imperial gallons per minute (gpm) or in liters per minute (lpm). Flow may also be expressed in liters per hour, liters per minute, liters per second, or in cubic meters per hour or m3/h
  • The pumping Head (H)

    or lift height to which the pump must raise the wastewater. Head can be expressed in feet, meters, or in pressure such as psi, Kpa, bars, or psi.
  • The pump design

    or type to be employed. Every manufacturer will provide help in choosing which type of pump you need to use. Types of pumps listed by Grundfos (and other manufaturers) include:

    Circulator pumps - such as used in hot water circulating or in heating systems
    Endsuction close coupled multi-stage pumps
    Encapsulated pumps
    Submersible wastewater pumps - this is the type you will need for a typical residential sewage or septic pump
    Submersible groundwater pumps - this is the type of pump you'd use to get rid of groundwater under, or around a building
    Immersible pumps
    Inline single-stage pumps
    Inline multi-stage pumps (greater pumping capacity or lift)
    Boosgter set pumps
    Diaphragm pumps
  • Pumped liquid:

    typically for a sewage pump or septic pump or even a sump you'll assume "water''. Special pumps are required to handle other liquids such as glycol or corrosives.
  • Liquid temperature & viscosity during operation

    Typical assumptions would be 68 degF and Viscosity of water or 1.
  • Liquid density

    typical assumption = 62.29 pounds per cubic foot or lb/ft3
  • Pumping operating environment / conditions,

    including Voltage (typically 120 VAC or 240 VAC), Altitude above sea level, Ambient temperature, and NPSH or Net Positive Suction Head.
    For completeness.

Is there an Inline Sewage Grinder Pump to fix a problem of inadequate drain line slope?

I purchased a modular home 14 years ago, it's 66 ft long and I don't feel that the drop angle of the drainage pipes from the home to the septic is right. Is there a inline ejector pump available? - B.K. - 3 Aug 2013

Reply: yes but inspect and diagnose the drain problem first

A competent onsite inspection by an expert usually finds additional clues that would permit a more accurate, complete, and authoritative answer than we can give by email alone. You will find additional depth and detail in articles at our website. That said I offer these comments:

I'm not sure I correctly understand what you are asking about with the term "inline ejector pump" but I am guessing you want to know if there is a sewage pump that is placed horizontally in line along the route of a drain system.

A problem faced by simple residential sewage grinder pumps is that we need a way to know how to turn the pump on and off when needed - manufacturers solve this problem with a modest plastic reservoir chamber; sewage or wastewater flows into the reservoir; when the wastewater level reaches a level high enough to justify a pump-on cycle, a float switch turns on the pump which grinds and pushes sewage to an outlet plumbing line.

Indeed there are types of "in line" sewage grinder pumps available from severasl manufacturers listed in our

article SEWAGE PUMP BUYERS GUIDE & MANUALS including Crane.

A quick search of inline grinder pump products returns first high capacity municipal sewer system pumps that are not intended for residential use.

For example, and quoting from Crane, include pumps handling flows up to 1,200 gpm and fitting pipe diameters with a 1-4" discharge. Inline pumps are available in both vertical and horizontal pipe hookup models, and some industrial models are indeed intended for sewage pumping such as

JWC Environmental's Muffin Monster

The Muffin Monster sewage grinder has proven itself over the last four decades in the most demanding wastewater solids reduction applications including pump stations, sludge lines, receiving stations, fish processing facilities, prisons, jails and more. - jwce.com

Some smaller inline sewage pumps as well as larger municipal equipment include

Watch out: not all of these are intended for sewage pumping:

Deming Inline Pumps feature a space saving, back pull-out design which allows versatile applications in a wide range of industries. Available in 11 size configurations. ANSI pumps meet the dimensional requirements of ANSI B73.2. - Crane Pumps and Systems

Weinman In-line pumps are specifically designed for heating, air conditioning and industrial applications. Suction and discharge nozzles are located 180° apart on the same centerline for mounting directly in a pipe line.

This eliminates critical pipe alignment for ease of assembly and minimum pipe strain. The need for costly foundations is eliminated, which guarantees minimum space requirements.
- Crane Pumps and Systems - cranepumps.com

I offer these suggestions to address your concern for possibly inadequately -sloped building drain piping that is resulting in clogs and backups:

1.Before buying and installing a grinder pump, inline or reservoir type,

it makes sense to get an accurate diagnosis of the actual problem. Indeed my cousin's bragging about the great deal he got on the price of a house in Phoeniz was mitigated by the discovery that when he flushed toilets sewage came up through the first floor bathtub drain.

An investigation by a savvy plumber included some elevation measurements easily made by checking the depth and elevation of the drain line at various cleanouts. He found that the builder had installed a long nearly-flat building drain line between the house and the sewer line. The fix was not easy nor cheap and would have involved excavating to re-set the line.

But more often recurrent sewer line clogs and backups are due to a more localized problem such as a partly broken, cracked, root-clogged, or otherwise impeded section of a drain line.
