Traditional sewage lift stations work well, but can have their drawbacks. Thanks to modern methods, there are options which can increase efficiency and save money. There are also other important benefits to consider. Here is a look at traditional pumping methods and how they can be improved.
A waste water pumping station is necessary whenever the problem of higher elevations is faced. A conventional station for pumping includes a dry well, as well as a wet well. Both wells are in the same general area for efficiency, and are often part of the same structure. The dry well contains the pump motors and their inlets extend below ground level into the wet well. This configuration allows for automatic pump priming. It also allows for the highest net positive suction head, also known as NPSH. NPSH is needed for an effective hydraulic system.
A conventional sewage lift station pump has a dry well with pumps mounted above the ground. This is done to protect them from any flooding. Pump motors incorporate long shafts and they extend into the wet well area. As pumps are above ground, they must have protection from the elements, in the form of a housing.
Modern day options include package sewage lift systems. They offer a great deal of convenience and eliminate the need for dry wells. The package system is usually complete from the factory and comes with the wet well, pumps, pipes, valves, control panels, junction boxes, and an alarm system.
Packaged pumping stations feature pumps that are submersible. They can be either grinder pumps or solid handling pumps. The wet well in this kind of system is not intended for storage and its simple operation requires fewer controls than conventional systems.
A packaged pumping station provides a lot of benefits over other kinds. As the pumps are submerged, the entire operation takes place under the ground. The pumps do not require special protection from the weather, so no special housing is required. There is not a great deal of maintenance needed on a packaged system, either.
Packaged pumping stations are easy to install, and everything that you need comes with the kit. Life expectancy of these systems can be as long as 20 years, which is above average. These systems take up a smaller footprint on the land, as the only visible structure houses the control panel. Everything else is below ground, as the pumps are completely submerged. Also, many of these systems are designed to handle high capacity and have redundancy features in the event of one pump not working.
Sewage lift stations have many options today. For example, there is no need to have a dry well, as in the past. Modern systems include the use of a packaged pumping station which comes complete from the factory. These systems are easy to install and maintain, and can save a lot of money on operating costs. It is an excellent way to increase the efficiency of a modern day waste system.
