Former Plittersdorf waterworks
The former waterworks in the Plittersdorf district of Bonn was built around the turn of the century and today serves as the headquarters of the Bonn company Solarworld . The buildings of the former Rhine waterworks are located at Martin-Luther-King-Straße 24 and are under monument protection.
history
Under Godesberg's mayor Anton Dengler , construction of the waterworks began at the end of the 19th century, initially consisting of the waterworks and a machinist's house. The work was housed in a single-storey, rectangular plastered building with a tile-covered saddle roof, divided by three window axes across and five axes lengthways. The Plittersdorfer Aue , about 200 m from the Rhine, was chosen as the location . The plant drew its water from the Rhine, which was first cleaned by bank filtration in the soil and later, after being extracted from a well, using activated carbon filter cleaning in the plant's treatment systems. From the end of the 1950s, additional buildings (for modern filter systems and a pump house) were built. In the higher new building there were eight or six meter high steel tanks that were equipped with activated carbon filters for water purification.
In 1982 there was a media scandal about water quality. An official, Winfried Edel, had claimed in a letter to the editor on December 28, 1982 in the Bonn local paper “Blickpunkt” that the carbon filters of the Plittersdorf plant were not able to remove all the toxins present in the Rhine. This would apply to ortho chloronitrobenzene to, a toxic nitro compound, which was measured at the time in elevated doses in the Rhine and probably from wastewater discharges of Hoechst AG came, the branch factory Griesheim had a discharge permit for this toxin.
The Plittersdorf waterworks supplied up to 300,000 residents in Bad Godesberg and Remagen with over six million cubic meters of water a year - at a time when the city of Bonn was already being supplied with reservoir water. Bad Godesberg was one of the last towns in the area to be supplied with drinking water obtained from Rhine water filtrate until 1989. Since the end of the 1980s, as a result of the incorporation of Godesberg into Bonn, the drinking water supply had been switched to supply from the Wahnbach dam. The waterworks was finally shut down in 2004.
Use today
In 2007, the CEO earned SolarWorld , Frank Asbeck , the work of the city. Under the architect Ralph Schweitzer, the building from 1901 as well as the also listed extension from the 1960s were converted into offices and a small museum of solar technology so that the industrial character of the facility was preserved. The younger part of the building was raised, the processing tanks set up here were cut up so that they could be converted into slightly elevated workplaces for the marketing department. The former control center has been redesigned into a reception area that roughly corresponds to the original with its dark brown wall paneling and recessed fittings.
The system is heated by means of a heat pump system with machines from the Waterkotte brand. This system uses the old well of the waterworks for this purpose, whereby the Rhine water there is cooled and the office can be supplied with district heating. The old company headquarters of the Solarworld Group ( the former Saarland representative ) on Kurt-Schumacher-Strasse was sold to the post office after the move .
