Type of System. 33.5 minutes per inch. Shallow trench system for the primary site(holes 1-4). 2. Proposed Flow Rate. 3 bedrooms 9 150 G.P.D. = 450 G.P.D. 3. So i 1 Treatment Area Requ i red . 2.0 percolation rate factor x 450 G.P.D.= 900 Sq. Ft. minimum. 4. Size and Number of Trenches. 3 trenches 3 feet wide and 100 feet long = 900 Sq. Ft. These trenches would be spaced a minimum of 7.5 feet apart center to center and be no deeper than 1.5 feet near soil boring # 1. 5. Grainfield Flock Needed. 33.3 cubic yds. of rock is needed to have 6 inches under and 2 inches over a 4 inch distribution pipe. 6. Septic Tanks. Two septic tanks each of 1000 gallons are recommended. In addition, it appears that a third pumping tank and pump will be needed to reach the higher drain - field area. 7. Additional Information. Drainage must be diverted from the drainfield area and no grading or construc- tion traffic is allowed on either the primary or alternate drainfield sites. All construction and materials must adhere to the provisions of the City of Orono. If there are any other questions, please contact me. Sincerely, PERCORR, INC. Mark S.
