Büchel is a small community in the district of Sömmerda in Thuringia (Germany). As part of the implementation of the European Urban Wastewater Directive, the 84 properties in the village were to be connected to the public sewage system. Until 2020, the wastewater of the approx. 300 inhabitants was channelled into three-chamber sewage treatment plants, each of which was located on the properties.
Backpressure protection with PKS pumping stations

First of all, it had to be clarified which of the three possible variants could be the most sensible and economical wastewater solution for Büchel. The choices were sewage disposal via gravity sewers, via pressure drainage or via fully biological small sewage treatment plants on each property.
Good arguments
Our field service colleague on site, Frank Hauer, was able to provide the right arguments, so that the decision was finally made in favour of pressure drainage. One reason was the high groundwater table in the area, through which the Unstrut River flows very close by.
It is much cheaper to drill small pressure pipes through the ground than to dig deep trenches for large pipes. To create a gradient, these trenches would have had to be much deeper and, in addition, groundwater lowering would have been necessary here.
Decentralised is the new trend
Once the project is completed, the wastewater from all 84 pumping stations will flow into a small treatment plant built specifically for the village. This is a new type of decentralisation that is becoming more and more common for small towns of up to 300 inhabitants. This saves long pipelines to remote central sewage treatment plants.
Used pump technology
A total of 84 PKS-B 800 sewage pumping stations, 84 HighLogo control units and 85 MultiCut sewage pumps were delivered. This means that the entire town is drained with reliable Jung Pumpen sewage technology.
