As per our conversation the residence has an existing failed septic system. 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 35 ft long absorption bed with 4 - 30 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. Due to the depth of the existing septic tank an air vent will be required on the end of the absorption bed pipe system. Please feel free to contact me at 796-2515 if you have any questions and that you for your assistance with this request. Sincerely;:..-- ;_ - __ ._ _ — -- 11-264/4, Thomas R. Center Jr, P.E.
