Abstract
A tipping pit water reclaiming system for concrete reclaimers which includes one or more tanks with a pivot support and hydraulic pistons for tipping the tanks to remove the settled solids. Clarified water from the tipping tanks overflows into a pump tank where it is returned by pump to the reclaimer. The pump tank includes a second pump for pumping excess clarified water into a storage tank for return to the tipping tank after the cement solids have been emptied out of the tipping tank. The second pump prevents the overflowing of water onto the ground from the tipping tank or pump tank as solids accumulate in the tipping tank. The second pump is controlled by float activated switches positioned at predetermined levels within the pump tank.
