CONSTITUTION: A non point source pollution removal gutter comprises a first chamber(10), a screen(20) and a second chamber(30). The first chamber is formed in a cylindrical shape. The first chamber comprises an inlet opening(11) and a connection opening(12). The inlet opening receives the rainwater. The connection opening transfers rainwater passing through the screen to the second chamber. The screen passes the rainwater to the outside of the screen and filters the contaminants contained in the rainwater. The screen is attached on and detached from the inside of the first chamber by a support. The second chamber comprises a curved inflow section(31), a stay section(32), and a lower opening(33) and an outflow section(34). The curved inflow section induces the rainwater inside the screen. The stay section collects and stores the rainwater passed through the screen. The lower opening make the rainwater flow from the first chamber to the stay section. The outflow section discharges the rainwater from the stay section.
