How do commercial wastewater pumping stations work? Liquid enters the tank through one of the inlet pipes. As the tank fills, a float switch or level sensor activates the pump, causing it to discharge the liquid. The pump continues until another switch or sensor signals it to stop. This cycle repeats as needed. If the pump fails and the tank continues to fill, a high-level alarm is triggered to alert you.
Sewage pump stations are commonly used for handling wastewater, stormwater, and effluent. They are often known as sumps, sewage pits, wet wells, dry wells and effluent chambers. Different types of wastewater pumping stations are available to suit various needs.
Regular servicing and maintenance of sewage pump stations is essential and can save thousands of pounds by addressing small issues before they become major problems. A minor fault, if left unresolved, can quickly lead to serious consequences such as flooding or equipment failure. For example, replacing a failed float switch may only cost a few hundred pounds, but ignoring it could result in a pump running dry—potentially causing damage that costs thousands to repair or replace.
Wet Well Pumping Stations
A wet well pump station is a below-ground tank or chamber with a pump submerged in the liquid. These systems typically include two pumps for backup, though some may have only one. Storm pump stations often use three pumps to handle varying flow levels. A level control system monitors the wastewater, and the pump discharges the liquid through pipework and non-return valves.
Dry Well Pump Station
Dry well pump stations usually consist of an underground tank with a separate dug-out room or basement beside it. Pipes from the base of the tank connect to the pumps and valve system in this room. Since the pumps are not submerged in liquid, they are easier to access and maintain. Dry wells are often found in older buildings and larger applications.
The underground room housing the pumps and valves is often considered a confined space due to limited access. Dry wells are becoming less common due to the high cost of construction and improved reliability of submersible pumps, which reduces the need for this type of setup.
Above Ground Pumping Stations
Above ground pumping stations, also known as lift stations, are compact, packaged systems used where traditional pump stations are not practical or cost-effective. These units are designed to be durable and space-efficient, allowing installation in basements, under cabins, or in other tight areas.
Both single and twin pump systems are available, and each includes an integrated level control and control panel. These systems are generally used for lower flow rates, typically up to 38 l/s.
