A reclamation system for the recycling of components of fluid concrete (such as concrete fines) and for concrete plant wastewater includes a slurry batch supply vessel which meters process water to a concrete batch mixing plant for use in concrete production processes, and a slurry retention vessel which collects stormwater, concrete truck washout, and other plant waste and wastewater for supply to the batch supply vessel when needed. The retention vessel, which may be no more than a waste pit, includes a fluid supply circuit which supplies water and suspended solids to the batch supply vessel, and a recirculation circuit which collects water and suspended solids from the retention vessel (or from the supply circuit) and reinjects the collected water and solids back into the retention vessel to agitate settled solids back into suspensions (so that they may be taken up by the supply circuit). As a result, the retention vessel will empty itself of accumulated water and waste solids and supply them (via the batch supply vessel) to the concrete batch mixing plant for recycling, rather than requiring the cost and inconvenient of periodic manual emptying.
