CLAY PIPE UNDERDRAINS-PLAIN OR PERFORATED?

COMPARATIVE TESTS WERE CONDUCTED ON PERFORATED CLAY PIPE AND PLAIN CLAY DRAIN TILE. COMPARATIVE PERFORMANCE TESTS WERE CONDUCTED OVER A PERIOD OF APPROXIMATELY NINE MONTHS ON THREE-FOOT LENGTHS OF PERFORATED CLAY PIPE AND ON ONE-FOOT LENGHTS OF PLAIN (SOLID) CLAY DRAIN TILE OF THE TYPE THAT HAS BEEN MOST COMMONLY USED IN ROAD BED CONSTRUCTION. WATER AT PRECISELY CONTROLLED FLOW RATES, WAS PUMPED OVER THIS SIMULATED ROAD BED AND MEASUREMENTS WERE MADE AT THE EXIT END OF THE BOX. THE THREE-FOOT PERFORATED PIPE WAS MUCH EASIER TO LAY. PERFORATED PIPE, AS PROVED BY THE DATA OBTAINED, WAS FOUND TO HAVE DEFINITELY SUPERIOR WATER REMOVAL CHARACTERISTICS AT FLOW RATES BELOW 100 GPM. IT IS CONCLUDED THAT THREE-FOOT LENGTHS OF PERFORATED CLAY PIPE HELD TOGETHER BY BAND CLIPS ARE MORE EFFECTIVE THAN CONVENTIONAL ONE-FOOT LENGTHS OF CLAY TILE AT NORMAL DRAINAGE FLOW RATES.
