PROBLEM TO BE SOLVED: To provide water treatment equipment which is miniaturized, easily installed and enables a countermeasure against overflow without enlarging the burden of a sewage disposal plant. SOLUTION: The water treatment equipment has a manhole into which combined sewage flows, a separator which receives the sewage from the manhole and separates the sewage into treated water and sewage, and a vortex valve which discharges the sewage. The manhole 2, the separator 3, and the vortex valve 4 are integrally provided in one treatment tank 1A. In the treatment tank 1A, an inflow pipe 34 which guides the sewage to the manhole, an outflow pipe 38 which flows out the treated water from the separator out of the vessel, and a discharge pipe 41 which discharges the sewage out of the vessel via the vortex valve are provided projectingly from the peripheral wall of the vessel, respectively, or are connectable to the peripheral wall of the vessel.
