PURPOSE: A collector well is provided to filtrate foreign materials included in rainwater, thereby preventing the blockage of a rainwater drain path. CONSTITUTION: A collector well comprises a main body(10), a drainpipe(20) which is connected to the main body and river or surrounding waterway, a cover(30) installed in the main body to support the weight of pedestrians or vehicles and filtrate foreign materials included in rainwater, a deposition tank(40) which divides the inside of the main body and has a through hole(42), a filter(50) which is installed at an interval from the through hole and filters foreign materials included in rainwater, a water pressure maintaining unit which is installed between the filter and the through hole to prevent the foreign material accumulated in the deposition tank from being carried toward the filter, and a barrier(70) which prevents rainwater and foreign materials from flowing to the through hole without passing through the filter. |
