A new plastic septic tank was installed in 2017 and after the tank was installed the owner installed a new deck configuration. Based upon our findings, there is a deck pile (sonotube) 67' from the edge of ST1 to the edge of the closest sonotube. Per the owner, the inspecting engineer, Zachary Meehan, P.E., has went out to the site and painted the perimeter of the tank on the ground. The owner has stated the closest edge of the tank is 4 feet from the painted perimeter to the edge of the tank to this sonotube. This is consistent with our field measurements. Per the owner, this sonotube extends approximately 3 feet below grade. Based upon these assumptions and our field measurements, a cross-sectional profile drawing was prepared showing the sonotube, the tank, and a 45 -degree angle originating at the bottom of the sonotube and projecting towards the tank. As can be seen on the drawing, the 45 -degree line intercepts near the base of the tank. The new septic tank is HDPE plastic and is therefore not subject to gradual corrosion and ultimate structural failure. Furthermore, the tank has only about 3.7 feet of soil cover, so it is not subject to an extreme soil load at this time. In short, structural failure of the tank is unlikely to occur and induce failure of the nearby sona-tube. The deck height is fairly low (see attached photo), so if the subject sona-tube were to become compromised, it is reasonable to believe that there is limited risk to life/safety. Also, it is important to note that the required five (5) feet separation distance between a deck support and a septic tank is a relatively new code requirement. For decades, this type of encroachment was allowed. Given these factors, the risk associated with this encroachment (4 feet of separation between tank and deck support) appears to be relatively low. Please do not hesitate to call me at 337-6179 if you require further information. Thank you for your assistance.

Garness Date: t ► 10/2Z) in conducting this evaluation, GEG provided an engineering evaluation of the well and/or septic system in accordance with the guidelines and regulations established by the Municipality of Anchorage and industry practices. The reported results describe the condition of the system/s on the date/s of the evaluation. Separation distances were measured to readily identifiable features. Hidden defects or encroachments may exist that were not identified during the evaluation. The operational life of all wells and septic systems depend upon a variety of variables, including but not limited to, soil conditions, groundwater levels (that may Fluctuate during the year), quality of construction (materials and workmanship), and the water usage of the family utilizing the system/s. These conditions can vary, and are outside the control of GEG. Satisfactory test results do not guarantee future performance of the system/s; therefore, GEG makes no warranty (express or implied) regarding the future performance of the well or septic system. GEG makes no representation whether an alternative well or septic system can be installed on the property in the event either of the current systems fail to perform adequately in the future. The content of this report is for the sole benefit of the person/party that retained GEG to perform the evaluation.
