f <br /> and McGrath, They were going to be preparing the design and permitting <br /> for the OAR systems out at Deer crossing. What they were talking about <br /> doing is upgrading systems A, B and D. What they would be doing is <br /> placing the OAR system components in between the existing septic tank <br /> and D-bo c. The initial component after they bleed the settling tank would <br /> be ars OAR tank, which they call a 'T'I. That was where they aerate and <br /> nitrify the effluent. The second tank they call T . That was the <br /> denitrification tank. From there they flow by gravity to the D-boxes or in <br /> the case of building A because they couldn't make it by gravity they would <br /> need to install a pump chamber. What he had was material to pass around <br /> the table was a conceptual... <br /> Mr. Ball asked if the location on the plan was carbo's. <br /> Mr. Hajjar replied that it was carbo's and Michelle's. <br /> Mr, Tint Santos noted that building B is office and retail. <br /> Mr. Hajjar added that building B also had a couple of restaurants. <br /> Mr. Tim Santos showed the board members some conceptual layouts so <br /> that they could understand the relationship between Til and T2, the septic <br /> tank and the D-bo . They currently have three of these systems on-line <br /> out at Otis Air Force base in the testing facility. They put through the test <br /> results from December through the current date for the septic. They have <br /> the total nitrogen for T2 and T1 and the sump. All of the systems out there <br /> are wrapped in a bag to collect the effluent to go to the treatment plant <br /> prior to discharge. <br /> Mr. Bail asked whet the flow design was, <br /> Mr. Tim Santos replied that at the testing facility they were currently <br /> sized for 330 CPD. <br /> Mr. Newton interjected that it was 440 GPD in triplicates <br /> Mr. Ball re-iterated 440 GPD times three. <br /> Mr. Newton stated that that was correct. <br /> Mr. Tim Santos continued by stating that basically if they ran through the <br /> numbers they were probably averaging total nitrogen from the septic tank <br /> of 38, The total nitrogen leaving the sump was around eight. This was a <br /> quick bar graph to show that reduction. The total nitrogen leaving T2 was <br /> around 14 ont average. <br />
