PURPOSE: A nonpoint pollutant removal apparatus for a rainwater drain pipe is provided to maximize filtering efficiency of various nonpoint pollutants and extend the filter replacement cycle. CONSTITUTION: A nonpoint pollutant removal apparatus for a rainwater drain pipe comprises a water collection pipe(10) which is connected to a roadside drainage to dispose rainwater on the road, a discharge pipe(20) with top connected to the upper side of the water collection pipe, a sediment box(30) in which the bottom of the water collection pipe is connected to the top and which receives rainwater, a filter(40) which filters nonpoint pollutants from the rainwater passing therethrough, and a water purification pipe(50) which connects the filter and the discharge pipe to discharge high quality water to the discharge pipe.
