Sewer Lift Stations often referred to as pumping stations, are necessary to pump raw sewage or waste-water from lower elevations to higher elevations, especially when the elevation of the source is not sufficient for gravity to do the work. Another reason for its use is when the use of gravity conveyance would result in excessive excavation and increased construction costs. In many cases, it just makes economical sense to use a pumping station to move the sewage or waste-water over a crest and then let it flow by gravity to a waste treatment plant.
The lift stations are typically built as a fully assembled system. Key parts of lift stations include a waste-water or sewage receiving well, known as a wet-well, that has lift pumps and piping, a junction box, and a control panel with an alarm system. Properly designed wet wells is are essential to the efficient and hassle-free operation of a pump station. The wet well allows for automatic operation of the pump station with a simple control. The ideal wet well is as small as possible so that retention time of the sewage is kept at a minimum.
Pumping stations, like those installed by All Pro Plumbing, are designed so that only one pump or set of pumps can accommodate normal peak flow rates. Safeguards are built into the system in case something causes one pump to fail, the remaining pump or pumps will take over and handle the flow. A major advantage of submersible Sewer Lift Stations is that they are less costly than their dry-well counterparts and require less pump maintenance.In addition, they don’t usually have large above ground structures and blend in seamlessly with the environment. In keeping with the trend toward leaving a smaller footprint, submersible lift or pump stations have essentially overtaken traditional waste-water pumping stations as the preferred equipment.
In most cases, the anticipated life expectancy of steel pumping station is 15-20 years. This is more than adequate as the anticipated waste-water flow rates are typically rated for only ten years of expansion. In addition, steel pumping stations are coated with high solid epoxy paints and also protected by anodes that deter cathodic action. You can also follow them Twitter.
