Germany – Engineering design services – Planungsleistung zum Neubau der mechanischen Reinigungsstufe unter Beachtung der Prinzipien von Cradle to Cradle (C2C)

The Arnsberg – Neheim wastewater treatment plant is being completely overhauled in the entire sewage sector, as it has a strongly outdated M- and E-technology (often 20 and over 30 years old). Due to the tense spare parts situation and the no longer sufficiently powerful mechanical cleaning, the construction of a new mechanical cleaning plant including inlet screw pump station, screen and sand trap, as well as the renewal of the primary settling tank rake, is to be implemented as a priority measure. Goals of the measures: • Safe sewage conveyance by screw pumps to the new mechanical sewage treatment for mixed water inflow up to QM: 880 l/s • Operationally safe discharge of substances > 5 mm • Operationally safe discharge of sands > 0,2 mm • Operationally safe primary sludge and scum removal. A new screw pump station, a new screen plant and a new sand trap plant are to be provided in parallel to the ongoing operation. The sludge rakes of the two primary settling tanks will also be renewed. The high-rise construction components to be renewed should be inspired by circular approaches (Cradle to Cradle principles). Further components of the planning should also be considered in accordance with the principles of c2c, cross-plant questions should be answered and an overall concept should be developed. For this purpose, the overall concept submitted as part of the tender for the integration of C2C principles in all phases of performance is to be further developed and taken into account in coordination with the contractor. This involves special services according to HOAI. The planning of the high-rise construction components should be based on the principles of Cradle to Cradle.
