To shorten a time until siphon force is generated in a case where a flow rate of drainage water is low.SOLUTION: A siphon drainage system 10 includes: a gradient pipe 22 that is inclined downward toward a downstream side and passes drainage water from water-use equipment; a lateral pipe 30A that is connected to the downstream side of the gradient pipe 22, has an inner diameter made smaller than an inner diameter of the gradient pipe 22, and passes the drainage water in a horizontal direction; a vertical pipe 30B that is connected to a downstream side of the lateral pipe 30A and generates siphon force by allowing the drainage water to flow downward from the lateral pipe 30A; a branch pipe 36 that branches midway in the gradient pipe 22; a retention tank 24 that can retain the drainage water and includes an inflow port 24A connected to the branch pipe 36 into which the drainage water flows and an outflow port 24B from which the drainage water flows out; and a junction pipe 38 that connects the outflow port 24B and the lateral pipe 30A.SELECTED DRAWING: Figure 2
【課題】排水の流量が少ない場合におけるサイホン力が発生するまでの時間を短縮する。【解決手段】サイホン排水システム１０は、下流側に向かって下方へ傾斜し、水廻り機器からの排水を流す勾配管２２と、勾配管２２の下流側に接続され、内径が勾配管２２の内径より小径とされ、排水を横方向に流す横引き管３０Ａと、横引き管３０Ａの下流側に接続され、横引き管３０Ａからの排水を流下させることによりサイホン力を発生させる竪管３０Ｂと、勾配管２２の途中から分岐した分岐管３６と、排水を貯留可能とされ、分岐管３６に接続され排水が流入する流入口２４Ａ、及び排水が流出する流出口２４Ｂを備えた貯留槽２４と、流出口２４Ｂと横引き管３０Ａを接続する合流管３８と、を有する。【選択図】図２
