Abstract:
Method of controlling a vacuum waste system, which comprises a number of sources of waste (9), vacuum sewer piping (7) including at least a branch pipe (71) and at least a main pipe line (72), a discharge valve (8) having an inlet end connected to a source of waste and an outlet end provided with a given type of connection to the vacuum sewer piping, and a vacuum unit (11) connected to the vacuum sewer piping. Vacuum is generated in the vacuum sewer piping by the vacuum unit and a discharge sequence for discharging waste from the source of waste into the vacuum sewer piping is activated by a discharge sequence activating means (20), whereby the discharge sequence is set for a predetermined time. In order to achieve an optimized control of the vacuum waste system, the predetermined time for a discharge sequence for a source of waste is set according to the given type of connection (711, 712) of the discharge valve to the vacuum sewer piping or according to the location (L1, L2) of the discharge valve with respect to the vacuum sewer piping.
