CERTIFICATION & 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, indicates that the on-site water supply and/or wastewater disposal system appears to comply with applicable Municipal and State codes, ordinances, and regulations in effect at the time of installation, unless noted otherwise. Name of Firm FIRST WATER CONSULTING Phone 907-350-9566 Engineer’s Printed Name CURTIS HUFFMAN, PE Date 04/09/2026 Comments: This investigation was completed in compliance with MOA guidelines, regulations, and best industry practices / methods. The assessment of the condition of the well and septic applies only to the conditions as of the day tested. The flow and absorption rates may change due to subsurface conditions that may not be observed from the surface, changes in land use, local soil characteristics, groundwater levels that may fluctuate during the year, quality of construction (workmanship & materials), the water usage of the family being served by the system and maintenance. The operational life of all well and septic systems are subject to these various and dynamic characteristics and are outside the control of the evaluator of the well and septic system. Therefore, any or NO estimate of how long a system will function satisfactory for current or future occupants or guarantee that no unseen encroachments, deficiencies or discrepancies exist can be given by First Water Consulting & 04/09/26 MUNICIPALITY OF ANCHORAGE ;')rveloomrni Services Department , On Site Water artd Was7717r 7177 COSA NO.

Air coil in sand filter to be geoflow WF16-4-24 150 LF placed 6" above bottom of sand. Construction of Sand Filter The sand filter construction is to follow procedures as outlined below, as applicable to this design. Pea gravel and filter sand are to be hand leveled to proper depth (tolerance within 0.05 feet) in filter, taking care not to allow mud or fine soil material into the filter or gravel layer. This would include any soil material picked up by excavation machinery buckets while loading specified material. The ConWactor should estimate filter material volumes such that allowance is made for wastage of material in contact with the ground at site. The area over the sand filter to be finish graded with a minimum of 2 feet of cover and to prevent ponding of surface water mn off. Side slopes shall not exceed 3:1. The Engineer will reject any sand or pea gravel that does not meet specifications or is · contaminated in transit or while handling.
