Jeff Vaughan and Trevor Hackney of Agri-Waste Technology, Inc. (AWT) conducted the soil evaluation. This evaluation was done to facilitate permitting for a septic system. This report and attached documents were prepared to meet the requirements for an Authorized On-Site Wastewater Evaluator to meet G.S. 130A-336.2 A drawing of the site plan, septic layout, and boring locations is included in Attachment 1. Profile descriptions for each boring are included in Attachment 2. Additional documentation about the property is included in Attachment 3. This property is a subdivision of a larger property that will make up the Cardiff Glyn subdivision. This property area is approximately 1.1 acres. The property is a wooded lot. The home is proposed near the front of the property with the septic system proposed upslope of the home. The proposed septic system is a pressure manifold septic system utilizing a low-profile chambers dispersal product for the primary and repair system. The supply line will cross an intermittent stream (See Drawing Detail, Attachment 1). Soil Suitability for Domestic Sewage Treatment and Disposal Systems The drawing in Attachment I details the property boundaries (as proposed by Frank Craig), soil boring locations, and layout of drain field trenches (Completed by AWT). Soil borings were examined to determine soil suitability for on-site sewage disposal systems in accordance with 15A I 8A .1900 Rules for Sewage Treatment and Disposal Systems. These borings were advanced with a hand auger. 1 A septic layout was performed to demonstrate available space (.1945). The layout in Attachment 1 indicates there is available space for a four-bedroom primary and repair system utilizing a low-profile chambers dispersal drain field product. The proposed LTAR(Long Term Acceptance Rate) by AWT is 0.3 GPD/ft2. The soils on this property are group IV soils within the distribution and treatment zone as used to define the LTAR. Since usable slope corrected soil depths meet or exceed 27" AWT is recommending the use of the low-profile chamber dispersal product. The maximum trench bottom should not exceed 15". With an LTAR of 0.3 GPD/ft2, 1068 linear feet of trench are necessary to support a four-bedroom home initial and repair system. The attached drawing proves that 536 linear feet of trench can be installed for the primary septic system. The attached drawing proves that 538 linear feet of trench can be installed for the repair system. Any disturbances or grading done in the usable area or within the proposed setbacks will change the potential of using the area designated for a drain field. We appreciate the opportunity to assist you in this matter. Please contact us with any questions, concerns, or comments.
