ABSTRACT:
A temporary trap having baskets and optionally filters in the baskets used in conjunction with curb inlets for sewer systems to keep debris from being washed into the sewer during construction of roads and sewers. The trap is a box, typically rectangular, square or round, with baskets having a plurality of holes therein for allowing water to pass therethrough while trapping debris therein. The trap is inserted into a curb inlet by lifting the grate off the curb inlet frame, inserting the trap and then replacing the grating. After a rain the baskets and filters may be cleaned out and reused. Optionally, when the construction project is finished the grate is lifted off the curb inlet frame and the trap removed. An optional cloth filter for insertion into the trap filters finer debris from entering the sewer system. The trap has an overflow opening in case the trap becomes clogged.
