PROBLEM TO BE SOLVED: To provide a treated water supply system which can prevent corrosion of a pump, and facilitates supplement of bactericides. SOLUTION: Rainwater flows from a yard catch basin 3 with a trap into a settling tank 11 of a water storage tank 10, and flows over a partition wall 14 into a main tank 13. When a pump 33 is driven, water in the main tank 13 is fed via arranged pipes 31, 34. When the water flows in the arranged pipe 34, a float valve 47 of a bactericide supply vessel 40 lowers, whereby a bactericide solution in a bactericide chamber 42 is supplied via a valve chamber 43 and a solution feeding port 48 into the arranged pipe 34.
