<p>PROBLEM TO BE SOLVED: To provide a waste water discharge system which allows easy switching of flow paths of waste water flowing from drainage equipment and facilitates avoiding cases where disasters hinder the switching of flow paths of waste water.SOLUTION: A waste water discharge system 1A comprises: a first outflow duct 11 connected to drainage equipment 7; a second outflow duct 12 connected to a main sewer 20; reservoir means 70; and an intercepting chamber 40. The intercepting chamber 40 comprises: a chamber body which has an inspection hole opening upward, an inlet 52 connected with the first outflow duct 11, a first outlet 53 connected with the second outflow duct 12, and a second outlet connected to the reservoir means 70; and switching means which can change positions between a first switch position, in which the inlet 52 and the first outlet 53 are in communication such that waste water does not flow from the inlet 52 to the second outlet, and a second switch position, in which the inlet 52 and the second outlet are in communication such that the waste water does not flow from the inlet 52 to the first outlet 53.</p> |
