Optimization potential for rain overflow basins Chur WWTP
At the Chur WWTP, HOLINGER evaluated the operating data of the rain overflow basin (ROB). This allowed us to derive initial measures to improve water protection. In addition, the analysis showed the potential for improving the operation of the ROB in terms of storage and discharge behavior. The experts now take additional samples in the overflow of the ROB and in the inflow of the WWTP ROB and determine the concentrations of various substances. These analyses will form the basis for limiting the future discharges of the ROB.
