d. Sites meeting the criteria for Innovative Systems set forth in Rule .1969, or <br /> other sites meeting the requirements for systems specifically approved by the <br /> State. <br /> V. System Sizing and Design Criteria: <br /> a. Septic Tank& Effluent Filter: The septic tank and effluent filter shall be <br /> designed and constructed in accordance with Rule .1952, .1953, and .1954 and <br /> sized in accordance with .1952 (b) (2)where "Q" is the largest projected 24 <br /> hour waste flow in the flow equalization cycle. <br /> b. Grease Traps: The grease trap shall be designed and constructed in accordance <br /> with Rules .1952, .1953, .1954 and .1955 (k)(3) and(k)(4). Grease traps at <br /> churches with kitchens shall be sized at a minimum of 1 gallon/seat [in the <br /> dining area]. The minimum liquid capacity of any grease trap shall be 1,000 <br /> gallons. <br /> c. Equalization/Pump Tank: The pump dosing tank shall be sized to allow for: <br /> i. Pump submergence: Effluent volume that covers the pump and the motor <br /> housing, or in accordance with pump manufacturer's suggestions, but in <br /> no case shall less than 12 inches of effluent remain in the tank at all times. <br /> The pump intake shall be at least 5" from the interior bottom of the tank; <br /> ii. Minimum Dose Volume: Minimum dose required based on the size of the <br /> nitrification field(see below); <br /> iii. Equalization Volume: The highest cumulative volume of effluent as <br /> indicated by the flow balance calculation; <br /> iv. High-Water Level Alarm: The high-water alarm shall be set to activate at <br /> or above the equalization volume; and <br /> v. Emergency Storage Volume: Effluent volume that equals Q as defined in <br /> V(a). <br /> d. Pump: In addition to the applicable requirements of 1952(c)(2), (3) and(4) the <br /> pump shall be sized to deliver the minimum required flow at the total dynamic <br /> head. The pump shall also deliver a flow that meets or exceeds a scour velocity <br /> of 2 feet/second, using Q = (V) (2.45d2), where V= scour velocity=2 <br /> feet/second and d= inside pipe diameter in inches. The minimum delivery rate <br /> at a residual operating pressure of 2 feet shall be at least: <br /> i. 13 GPM for 1-'/2 inch Sch 40 pipe, <br /> ii. 21 GPM for 2 inch Sch 40 pipe, <br /> iii. 46 GPM for 3 inch Sch 40 pipe <br /> e. Control Panel: The control panel shall meet State approval and meet the <br /> specifications set forth in Rule .1952 (c)(6)with the additional requirements of: <br /> i. High-water level alarm event counter <br /> ii. Timer over-ride counter <br /> 3 <br /> 103 <br />
