We have reviewed the proposed replacement septic system design and we agree that a standard absorption bed is acceptable.Based upon a design flow rate of 440 GPD and a percolation rate of 1 to 5 minutes,you will need a minimum of 489 sf of absorption area.We recommend using 20 ft wide by 30 ft long absorption bed with 4 -25 ft long laterals.The absorption system can be constructed with the existing 1,250-gallon septic tank,new distribution box,and 4-inch diameter perforated pipe and stone. Please feel free to contact me at 796-2515 if you have any questions and that you for your assistance with this request. Sincerely,JArwlipe— ‘Thomas R.Center Jr,P.E.
