A dispensing system (10) for dispensing a soluble but solid substance (20) and a corresponding method for dispensing are provide, the dispensing system (10) comprises at least a first container (12) and a second container (14) for keeping a solid substance (20), a solution reservoir (36) for holding a solution (34), at least one spray line (24,26) allocated to each container (12,14) connected to a water supply, at least one spray means (22) allocated to each container (12,14), wherein the spray means (22) is connected to the corresponding spray line (24,26), for bringing water from the water supply (28) into contact with the solid substance (20) being inside the first container (12) and the second container (14) such that an amount of the solid substance (20) dissolves and the thus resulting solution (34) flows into the solution reservoir (36), means, preferably at least one level sensor (38), for measuring the filling height in the solution reservoir (36), measuring means (40) for measuring the conductivity of the solution (34) inside the solution reservoir (36), at least one first discharge line (42), through which the solution reservoir (36) is connectable to a first tank (44), at least one first delivery pump (46) for moving the solution (34) from the solution reservoir (36) through the first discharge line (42), and an electronic main control unit (66) for controlling the operation of the dispensing system (10).
