Claim:
A wash-out system for washing concrete pouring equipment comprising: a base portion defining a set of receptacles each for receiving a removable bin and having a floor sloping to convey liquid drained from a bin received by a selected one of the receptacles to a sump area; a filter system including a plurality of pairs of settlement tanks separated by baffles defining a path allowing the liquid drained from the bin to cascade between the pairs of settlement tanks, wherein first and second ones of the settlement tanks of each pair of settlement tanks are separated by a first upward extending baffle providing a partial wall between the first and second ones of the settlement tanks and a second downward baffle spaced from the first baffle and extending into the second one of the settlement tanks; a filtering pump for pumping the liquid drained from the bin from the sump area of the base portion to the first one of a first one of the pairs settlement tanks of the filter system such that the liquid cascades over the partial wall provided by the first baffle and downward through a space between the first and second baffles into the second one of the first pair of settlement tanks leaving behind waste material in the first and second ones of the settlement tanks of the first pair of settlement tanks; a clean water tank for receiving and storing filtered water provided from another one of the settlement tanks; and a set of at least one bin removably received in a selected one of the receptacles of the base portion and for receiving wash-out waste material and having drain apertures allowing at least some of a liquid portion of the wash-out waste material, including particulate waste material smaller than the drain apertures, to drain into the selected one of the receptacles while retaining particulate waste material larger than the drain apertures within the bin.
