PROBLEM TO BE SOLVED: To provide an improvement means for a combined sewer system which suppresses the use of the land, reduced in load on each family, prevents environmental pollution even in heavy rain, and prevents damage caused by flood. SOLUTION: This sewage treatment system includes a system having a rainwater storage facility with a conversion improvement and flood prevention measures which branches initial polluted water from the system of a normal sewage treatment facility during a rainfall time and accepts and stores the branched water and a high-speed filtrating facility which treats the initial polluted water stored in the rainwater storage facility by a conversion improvement and flood prevention measures and discharges the treated water without allowing the treated water to pass the normal sewage treatment facility.
