Many investors decide to install a sewage pumping station, appreciating its advantages. Some still hesitate, which is mainly due to a lack of knowledge about it. In this article, we will try to present the most important information about the pumping station, regarding the principle of operation and costs, thus dispelling the most important doubts.

What is a sewage pumping station?
It is not possible to build a gravity sewage system everywhere. This is especially the case in areas with unfavourable terrain, but not only, because various construction obstacles can also affect it. Regardless of the cause, the investor must find the optimal solution to create an efficiently functioning sewage system. In reality, there is only one, but reliable way to deal with this problem - your own sewage pumping station. It automatically pumps sewage to a higher and further receiver, for example a well. And this is the main task of the pumping station - lifting sanitary sewage, polluted water, but also rainwater, drainage and meltwater, and then discharging them to the receiver.
Although this solution is very often used by owners of single-family houses, which results from the fact that gravity sewage is not available to them, they work perfectly in other places, such as housing communities, recreation centers or sports centers. What is more, sewage pumping stations are increasingly found on farms located far from the main sewage networks.
How much does a sewage pumping station cost?
It is difficult to answer this question unequivocally, because everything depends on the specific installation - its level of advancement, manufacturer or investment location. A precise valuation is possible when we take into account a number of technical parameters. On this basis, we can provide an approximate cost of the investment, which applies to both the pumping station and its assembly. Of course, the most important component of the pumping station is the tank into which the sewage is directed. It must be made of solid quality materials to fulfill its task properly. Its price depends on the size of the tank and the material from which it was made. Usually it is polyethylene. Another important element is the pump . The differences in costs can be significant here, because although the cheapest model will cost us about PLN 500, the most expensive one can cost up to PLN 7,000.
Other equipment elements, including piping, include pressure risers, check valves and shut-off valves, pump guides, pump chains, tank hatch, ventilation chimneys, etc. Taking these factors into account, it can be assumed that a minimum of PLN 2,000 is needed to buy a solid quality sewage pumping station. Of course, the installation costs, starting from PLN 1,500-2,000, should also be added to this estimate. However, as we have already mentioned, how much we will actually pay depends on the specific investment - its specificity, scope of works, size of the plot, etc.
How to select a sewage pumping station?
In order to choose a sewage pumping station for the needs of our home, we should remember a few rules that determine the correct operation of the device. One of the most important concerns the flow rate that the pump should have. It is important that it is greater than the flow rate of incoming sewage. This will allow it to work continuously even at maximum inflows. It is also extremely important that the pump can work at its optimal operating point. This guarantees proper use of power and its long service life. Let us also pay attention to the fact that the speed of sewage in the pressure pipeline reaches a minimum of 0.7 m/s. At a higher speed - 0.8 m/s - we are sure that all sewage will be removed, including that found on steep rising sections.
This is the most important information about domestic sewage pumping stations. On this basis, it is easier to plan your own investment, taking into account the costs of the construction itself, as well as the assembly. Certainly, in a very large number of cases, the choice of a pumping station is obvious, but it should also be considered by people who have other options, for example access to a gravity sewage system.
