The six weirs Erlabrunn, Harrbach, Steinbach, Rothenfels, Faulbach and Freudenberg on the Main federal waterway have exceeded their theoretical service life and technical problems are increasingly occurring. These six plants are planned in parallel by the WNA Aschaffenburg and comprehensively repaired at the same time or with a small time delay of about one year (solid construction, steel construction, hydraulic steel construction, telecommunications, electrical engineering, control technology, mechanical engineering) in order to bring them into a permanent and reliable condition and to achieve a further theoretical service life of 100 years.
