t 2 3 <br /> UNMASKED INFILTRATIVE AREA ft2/llneor fl <br />E~sed on 36" wide trench with 6" of grovel below' the pipe, <br /> <br />Documented research has <br />clearly demonslrated that <br />the INFILTRATORTM chamber <br />provides an optimum <br />infiltrative surface for <br />leaching systems. Several <br />states have already <br />recognized this and <br />granted system size <br />reductions accordingly. <br />The graph shows that <br />"INFILTRATORS "~ ha'v~ 2/3 <br />more effective infiltrative <br />surface area per linear foot. <br /> <br />assuming 50% gravel masking for sides and bottom compared to <br />standard and high capacity "INFILTRATORS" with 50% masking for <br />*INFILTRATOR" sidewall, and no bottom masking. <br /> <br />*INFILTRATORS ARE ENGINEERED AND <br /> <br />TESTED FOR INCREDIBLE STRENGTH. <br /> <br />Excovoled unit ofte~ Iood test showing no signs <br /> <br />SflucfuroIly tested by a Registered <br />Professional Engineer who is a <br />university professor of Civil Engineering, <br />INFILIRATOR'" chambers are available <br />with an A/~HTO rating of H-'10 <br />('16,0(]0 lbs./axle) with '12" of compacted <br />fill or H-20 (32,000 lbs./axle) with '18" of <br />compacted fill. <br /> <br /> <br />
