STATEMENT OF INSPECTION BY ENGINEER As certified by my seal affixed hereto and as of the validation date shown below, I verify that my investigation, based on procedures outlined in the Certificate of On-Site Systems Approval Guidelines for this application, shows that the on-site water supply and/or wastewater disposal system is (are) safe, functional and adequate for the number of bedrooms and type of structure indicated herein. I further verify that based on the information obtained from the Municipality of Anchorage files and from my investigation and inspection, the on-site water supply and/or wastewater disposal system is (are) in compliance with all applicable Municipal and State codes, ordinances, and regulations in effect at the time of installation. In conducting an adequacy test, I attempt to provide a thorough,conscientious engineering analysis of the system in accordance with MoA COSA guidelines and regulations. The reported results describe the performance of the system under the conditions encountered at the time of the test, and separation distances measured to readily identifiable features. The operational life of all wells and septic systems depend on the local soil condition,ground water levels that may fluctuate during the year,and the water usage of the family being served by the system.These conditions are outside the control of the evaluator of this system.All systems eventually fail and satisfactory test results do not guarantee future performance of the system, nor do they guarantee that there are no hidden defects or encroachments.Therefore we cannot provide any warranty for future performance, nor can we estimate remaining life of the system.The content of this report is for the sole benefit of the owner listed above.
