    Abstract: A water conservation system for a plating line comprising a series of treatment tanks and a plurality of rinse tanks utilizes timed inlets for admitting fresh water to each of the rinse tanks for a short period of time immediately following the introduction of a part into the rinse tanks. A sediment tank receives the discharge from each of the rinse tanks via overflow ducts, and a holding tankreceives overflow from the sediment tank. The contents of the holding tank are transferred to a treatment tank for batch treatment. A logic circuit controls sampling and testing of the treatment tank to determine the PH condition thereof and to initiate the addition of a predetermined amount of an appropriate neutralizer to the treatment tank.
