Sewage reuse system

A sewage reuse system, which distributes a plurality of reuse water supply sections, each of which includes a water introducing opening formed in a sewer trunk line;

• a treated sewage tank for storing reuse water that has been generated through a sewage treatment;
• and a water level sensor for measuring a water level of said treated sewage tank, in a demand area of reuse water along said sewer trunk line, comprising:
• a movable sewage treatment section which moves to any of said plurality of water introducing openings, performs said sewage treatment to generate reuse water, and supplies the generated reuse water to said treated sewage tank;
• a communication section which transmits said water level data measured by said water level sensor;
• and
• a central control section which controls a water storing quantity of each of said treated sewage tanks by moving said movable sewage treatment section to one of said reuse water supply sections which is located in a demand area of reuse water on the basis of the demand information of reuse water and said water level data received from said communication section.
