C5 6 <br /> CHANDLER CONCRETE CO., INC. <br /> READY MIXED CONCRETE <br /> POST OFFICE DRAWER 1239 <br /> BURLINGTON. NORTH CAROLINA 27215 <br /> (919) 226-1181 <br /> Page Three <br /> The normal water circulation will occur in the following manner. <br /> Truck wash water and plant run-off water will flow into basin #1 at the normal <br /> rate of 3000 gallons per day. It will take approximately 11 days to fill the <br /> basin water to a 4' level. In this basin all particles will settle to the <br /> bottom and clear water will flow into basin #2. A sump pump is installed in <br /> basin #2 and the sump pumps the clear water back to be used in the loads of <br /> concrete. The water is pumped into the trucks as temper water and as wash <br /> water. Excess water can be used in the plant if necessary. The water level <br /> in basin #2 be no higher than 2' during normal operation. <br /> During rainy periods the storm water run-off flows from the plant <br /> site into basin #1, settles out the particles and flows into basin #2. When <br /> basin #2 fills up the water automatically flows into basin #3. The pump is <br /> capable of pumping water from both basins. <br />
