PROBLEM TO BE SOLVED: To propose a means for removing toxic substances flowing-in a rainwater storage and infiltration facility. SOLUTION: The rainwater storage and infiltration facility is used to restrain the flow-out of rainwater. The facility includes a removal device filled with activated carbon for removal of the toxic substances dissolved in the rainwater, between a mud collector basin where the sand and mud present in the rainwater are precipitated and removed and the rainwater storage and infiltration tank, inhibiting the flow-in of the toxic substances. The activated carbon is employed to adsorb the toxic substances flowing-in the tank for removal. COPYRIGHT: (C)2011,JPO&INPIT
