Renovation of the Central Wastewater Treatment Plant (Darmstadt)

A look back: 1992 – 1994
Almost 30 years ago, the Darmstadt central wastewater treatment plant faced a major challenge: How could the existing old plant cope with increasingly heavy rainfall and rising water protection requirements? The solution was a groundbreaking conversion – now considered a milestone in sustainable water management.

The problem at the time:
Increased wastewater volumes and stricter requirements for treatment capacity necessitated an expansion of the central wastewater treatment plant in Darmstadt. In addition, the sewer network in Darmstadt and the surrounding communities quickly became overloaded during heavy rainfall. The treatment plant was also designed for wastewater treatment, not for the short-term storage and treatment of large amounts of precipitation. Untreated rainwater could allow pollutants such as oils, heavy metals, and suspended solids to enter the receiving water directly.
