Abstract: Systems and methods for recovering particulate matter washed from piece of construction equipment with water. Waste materials washed from the construction equipment are collected in a bin. The liquid in the bin is allowed to drain into a receptacle having a sloped bottom for conveying the liquid to a sump. The liquid in the sump is pumped to a first baffle box extending into a first settlement tank to remove a portion of the particulate matter in the liquid. The liquid cascades from the first settlement tank to a second baffle box extending into a second settlement tank to remove another portion of the particulate matter. The liquid is stored after removal of the portions of the particulate matter for recycling in a tank.

Abstract: A method of washing a piece of construction equipment includes washing a portion of the piece of construction equipment with water, collecting waste materials washed from the construction equipment in a bin, allowing liquid collected in the bin to drain into a receptacle having a sloped bottom for conveying the liquid to a sump, pumping the liquid from the sump, filtering the particulate matter pumped from the pump to recover clean water, and storing the recovered clean water for recycling in a tank.

Abstract: A system for washing-out concrete pouring equipment includes a bin for receiving waste materials washed with water from the concrete pouring equipment. The bin includes openings allowing liquid to drain into a base unit that includes sidewalls defining a receptacle for receiving the bin and a sloped bottom for conveying liquid drained from the bin to a sump. A filtering system filters particulate matter from liquid provided from the sump to recover the water.
