What is a lift station and how does it work?
A lift station is used to pump wastewater or sewage from a low level to a higher level when the gradient of the area does not allow for a natural flow. The wet well is a basin into which the inflow is discharged and where the pumps sit. The control panel is the brain of the lift station. Similarly one may ask, what is a lift station in plumbing ...
How much does a sewer lift station cost?

How to design lift station?
Jul 19, 2016 · Sewage lift stations are used for pumping wastewater or sewage from a lower to higher elevation, particularly where the elevation of the source is not sufficient for gravity flow and/or when the use of gravity conveyance will result in excessive excavation and higher construction costs.
How do septic lift stations work?
Defining Sewer Lift Stations. What is a sewage lift pump? They build a sewer lift station as a factory-assembled package. The principal elements of a sewer lift station include a receiving well for wastewater treatment and is equipped with lift pumps, junction box, piping with valves, and an equipment control panel that includes an alarm system.
What is the difference between a lift station and a pump station?
Lift stations are responsible for pumping wastewater or sewage material from a lower elevation to a higher elevation. On the other hand, a pump station is designed to raise water, not sewage or wastewater, to a higher elevation.Feb 25, 2019
Why is it called a lift station?
Utilities need lift stations to pump wastewater and sewage over, under and through different terrain. In fact, that's where they get their name: a lift station “lifts” sewage from Point A to Point B to account for elevation change.Sep 19, 2017

What happens when a lift station fails?
In the event of a lift station failure, by either a forcemain break, power outage, or pump failure, wastewater will collect in the lift station wet well and backup into the collection system.
Why do lift stations have two pumps?
The purpose for having these is that in normal operation the pumps switch back and forth after each pumping cycle. An alternator selects which pump will be the “lead.” This pump will turn on when the water level reaches the lead float.Apr 5, 2019
Do lift stations smell?
Ensuring a sewer collection system or lift station is free of odor is crucial to maintaining good relations with neighboring businesses and residents.Sep 11, 2018
How does sewage go uphill?
When the gravity sewer mains fill this basin, the pumps are activated by level switches. A switch is activated and the pumps pump the wastewater through a pipe called a force main. The force main pumps the waste water uphill until gravity can take over again.
Where does the waste from a macerator go?
The macerator pump uses a stainless steel fast-rotating cutting blade to convert solids and fluids into a fine slurry that is discharged under pressure through small-diameter piping (¾-inch or 1-inch) and expelled into the sewage line or septic tank.
Can you use a regular toilet with a macerator pump?

How can I tell if my lift station is working?
High Level Alarm The most obvious sign that there is a problem with your lift station is the high level alarm sounding. High water level alarms produce an audible and visual (flashing light) signal that the water level in the sump is rising.
How long do septic lift pumps last?
The average life expectancy is 5 to 7 years for a residential sewage pump and 5 to 15 years for a commercial sewage pump.Sep 19, 2018
Why is my lift station alarm going off?
When it overflows, your alarm may go off. Parts Problem – Your alarm will likely go off if one of your septic system's components is faulty. It could be your pump, floats, your timer – or the alarm itself. If you haven't had your system inspected by a professional, this is a good reason to have it done.Feb 4, 2019
Why is ventilation and heating required?
Ventilation and heating are required if the liftstation includes an area routinely entered bypersonnel. Ventilation is particularly important toprevent the collection of toxic and/or explosivegases. According to the Nation Fire ProtectionAssociation (NFPA) Section 820, all continuousventilation systems should be fitted with flowdetection devices connected to alarm systems to
What is a lift station?
Lift stations are used to move wastewater fromlower to higher elevation, particularly where theelevation of the source is not sufficient for gravityflow and/or when the use of gravity conveyancewill result in excessive excavation depths and highsewer construction costs.
What is a dry well lift station?
Lift stations are widely used in wastewaterconveyance systems. Dry-well lift stations havebeen used in the industry for many years. However,the current industry-wide trend is to replace dry-well lift stations of small and medium size(typically less than 24,000 liters per minute or 6,350gallons per minute) with submersible lift stationsmainly because of lower costs, a smaller footprint,and simplified operation and maintenance.
What is a wet well?
Wet-well design depends on the type of lift stationconfiguration (submersible or dry-well) and thetype of pump controls (constant or variable speed).Wet-wells are typically designed large enough toprevent rapid pump cycling but small enough toprevent a long detention time and associated odorrelease.
What are the characteristics of a lift station?
The overall performance of a lift station depends onthe performance of the pumps. All pumps havefour common performance characteristics: capacity,head, power, and overall efficiency. Capacity (flowrate) is the quantity of liquid pumped per unit oftime, typically measured as gallons per minute(gpm) or million gallons per day (mgd). Head isthe energy supplied to the wastewater per unitweight, typically expressed as feet of water. Poweris the energy consumed by a pump per unit time,typically measured as kilowatt-hours. Overallefficiency is the ratio of useful hydraulic workperformed to actual work input. Efficiency reflectsthe pump relative power losses and is usuallymeasured as a percentage of applied power.

It is critical that sewage lift station owners depend on professional drain and sewer cleaning service to maintain proper and sufficient the pump works sufficiently.
Do sewage pumping stations smell?
No, and this is by design and by nature. Because sewage, in its raw form, is unsafe environmentally and must be treated before it can be safe for the residents of a city or community. To make environmentally and healthy water and sewage service, sewage pump stations are necessary.
