Sanitary tees shall be bonded to the inlet or outlet pipe. <br /> B~ffles shall be integrally cast with the tank, affixed with a <br /> permanent waterproof adhesive, or afl, xed with stainless <br /> steel connectors, top and bottom. <br /> <br />?. The in]et baffle shall extend at least 6 inches, but not more <br /> than 20% of the total liquid depth below the liquid surface and <br /> at least 1 i~xch above the crown of the inlet sewer. <br /> <br />8. The outlet b~e and the baffles between compa~ments shall <br /> extend below the liquid surface a distance equal to 40% of the <br /> liquid depth, except that the penetration of the indicated <br /> baffles or sanitary tees for horizontal cylindrical tanks shall <br /> be 35% of the tots] liquid dept]m They also shall extend above <br /> the liquid surface as required in 4 above. In no case shall <br /> they extend less than 6 inches above the liqtfid surface. <br /> <br />9. There shaI1 be at least 1 inch between the underside of the top <br /> of the tank and the kighest point of the inlet and outlet <br /> devices. <br /> <br /> 10. The inlet invert shall be not less than 3 inches above the <br /> outlet invert. <br /> <br />11. The inlet and outlet sh~11 be located opposite each other along <br /> the axis of maximum dimension. The horizontal distance <br /> between the nearest points of the inlet and outlet devices <br /> shall be at 1 east 4 feet. <br /> <br />12. 'S~n~tary tees shall be at least 4 inches in diameter. Inlet <br /> baffles shall be no less than 6 inches or no more than 12 <br /> inches measured from the end of the inlet pipe to the nearest <br /> point on the bmtWqe. Outlet bm~es shall be 6 inches, measured <br /> from the beginning of the outlet pipe to the nearest point on <br /> the bm~e. <br /> <br />13. There shall be one or more manholes, at least 20 inches in <br /> dimension, and located v~ith~n 6 feet of any wall of the tank. <br /> The m~nhole shall extend to a point within 12 inches of, but <br /> no closer than 6 inches below, 6n~shed grade. The manhole <br /> cover shall be covered with at least 6 inches of earth. <br /> <br />14. There shall be an inspection pipe of at least 4 inches <br /> diameter or a manhole over both the in]et and out]et devices. <br /> The inspection pipe shall extend through the cover-and be <br /> flush with, or no more than 6 inches below', the finished <br /> grade. The top of the inspection pipe shall be provided with a <br /> readily removable water-tight cap. A downward projection of <br /> the centerline of the inspec~on p~pe shall be directly in line <br /> with the center ]~ne of the inlet or outlet device. <br /> <br />Printed 12/28/90 <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />! <br />I <br />I <br />I <br />I <br /> <br /> <br />
