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.

During the test the liquid level in the seepage pit was monitored as 1000 gallons were removed and 1000 gallons were pumped back into the seepage pit to the inlet level. All liquid levels were measured below the top of the standpipe and are shown in the following table: Initial Water Second 24-Hour Total Reading Added Reading Reading Drop (gallons) 7 ' 1" lO00 4 ' 4" 5 ' 2" 10" The average specific capacity is 30.3 gallons per inch° After twenty four hours the liquid level was measured again at 5 feet 2 inches. It had dropped 10 inches. This indicates an average effluent acceptance rate of 303 gallons per day for the surrounding soils. If the 2 bedroom residence on the property is to house 4 people, the average load on the system can be expected to be 300 gallons per day. We can therefore conclude that the system is disposing of effluent at an adequate rate for a 2 bedroom residence. We appreciate this opportunity to be of service to you. Please contact us if you have any questions regarding this letter or if we can be of additional service to you. VerTtruly yours, ~ary/~. Smith Project Manager GAS/rm/AT&SI~A ~CHANICAL ENGINEER DAVID S~]ENK~kMP ~94~-9055 N G 1 R IN ClIANICAL ENGINEERS CIVIL ENGINEERS SRB 196X Eagle River, Alaska 99577 ~IVIL ENGIMEER ~OBERT A. S[~FER 694-2979 Maureen Clayton Area Realty Eagle River, Alaska 99577 :.' .' s,!vmo,,,,:,. ~R.,(,- ]' , RECEIVED. Reference Lot 24, Eagle River Ranchettes property, owneo by Mr. Marvin Moore. An.adequacy test was conducted on the sewer system (septic tank and seepage pit) located on the referenced property on 30 and 31 March 1979. The septic tank was pumped and verified to have a capacity of 1,000 'gallons. The seeoage pit appeared to b~ full .of water. I: had approxi- mately 800 gallons removed from the pit, The pit'was then recharged with 900 gallons of water which left water standing in the clean-out pipe. At the end of 24 hours, water was still standing in the clean-out pipe. As a result, it Can be concluded that: (1) the clean-out pipe has been shoved down into the crib making an accurate measurement impossible, or (2) the system has completely failed. It is recommended that, after break-up, excavation of the crib should be performed to determine 'the exact depth of the clean-out pipe. If it has been extended into the crib, it should be raised to the top of the crib and a new adequacy test performed. It is estimated that this could cost approximately $300 to $400, including the adequa%y test. If St is found that the system has i:aii~d, then an upgrading ef the system will be required. It is estimated that the system can be upgraded at a cost of approximately $1500, providing that soils are suitable for the installa- tion of a leaching trench. ~/t~OBkRT A.
