Abstract: Apparatuses and methods can reduce washout water use and facilitate removal of waste. A transport vehicle can include a water holding tank, a washout tub, and a means for conveying water. Water can be conveyed from the water holding tank to clean concrete from utensils, chutes, pumps, and other implements through a hose. The water can then be separated from the concrete and conveyed back into the water holding tank using a hose and a strainer.

Abstract: A concrete strainer used to separate water from wet concrete can include a volume enclosed by a screen or holes in perforated material, connected to a vacuum hose. An extender pipe can be inside the volume and also connect to the vacuum hose. The screen or holes prevent aggregates in the concrete from entering the vacuum hose and clogging an attached vacuum pump. Advantageously, when the strainer is partially submerged into the wet concrete a portion of the strainer exposed to air allows water to flow by gravity into a bottom of the strainer. The extender pipe, being submersed in said water, prevents a vacuum from being lost due to exposure to air pressure.

Abstract: A concrete pump washout system which is mountable to transport vehicle(s); the system provides for the quick safe, and easy removal of all waste water and concrete used in the washout of concrete pumps and concrete truck chutes on a construction site. When applied to concrete pump washout, washout water and waste concrete are deposited into a tub, and a fluid vacuum pump is used to separate the water into a holding tank for later disposal. The waste concrete is left behind to harden in the tub, which may be disposable, for later removal to a disposal site, thereby freeing the concrete pump for the next job. When applied to concrete truck chute washout, water is removed from washout of the chute into the concrete pump hopper and pumped back into the truck hopper or into the washwater holding tank for later disposal, at which point the truck may leave and the pump is ready for the next load.
