Neuwied sewage treatment plant gets 1st solar folding roof in Germany
It’s a premiere in Germany: a large tank at the sewage treatment plant in Neuwied, Rhineland-Palatinate, is getting a solar roof that can be folded up. This is made possible by a Swiss innovation from dhp.
Conventional large solar plants need a lot of space, but that is sometimes in short supply. Servicebetriebe Neuwied (SBN) is therefore taking a new approach for Germany with Swiss technology. They are having one of their 1,600 square metre sewage treatment tanks built over – with a solar system that can be retracted when needed. “We want more energy efficiency in our operations,” explains SBN board member Stefan Herschbach. However, building over the clarifiers has not been practical so far because fixed roofs interfere with operations.
