FIELD: machine building.
SUBSTANCE: invention relates to water drain system (1) for a vehicle water management system. Vehicle comprises at least one flow region (2) at the bottom of the car through which air can flow, at least one water inlet, through which water can flow in, and at least one outlet of water through which water can flow. Inside flow region (2), flow turbulence means (4) is provided that includes water inlet, water outlet, and flow turbulence circuit (41). Flow turbulence circuit (41) is designed in such a way that near the water outlet it can form reduced pressure area (3), reduced pressure value in this reduced pressure area (3) is higher than the reduced pressure value available in the vehicle driving mode in the water inlet area.
EFFECT: improvement of the drainage properties of the system is achieved.
