# <br /> � <br /> September 13, 2005 <br /> Margazet Callahan <br /> 3265 County Rd. 6 <br /> Orono Mn 55356 <br /> Dear Sirs; <br /> Upon your request we did an inspection on the septic system at the above residence, the <br /> results are as follows. <br /> - The system was installed in 1988, Permit Number 1557 from the City of Orono. <br /> - This system consists of 2-1000 gallon septic tanks and 1200 square feet of gravity. <br /> Trench soil treatment area. <br /> - There does not seem to be any surfacing of sewage at this time, nor is there any <br /> - evidence of surfacing in the past. <br /> - The tanks appear to be of a precast construction and seem to be water-tight. <br /> -A soil boring was done approximately 15 feet north of the first soil absorption trench. <br /> -Mottled soil was encountered at about 36 inches below the surface. <br /> For the system to meet currant PCA and city codes it must have a 2-foot separation from <br /> the seasonal-grou.nd water table, or mottled soil. This system does not meet a 2-foot <br /> setback. This setback or ground water separation is part of the currant code. <br /> Upon e�mination of the records it seems as this system was installed as per the original <br /> design by S-P Testing dated 12-5-1988. <br /> At that time the City gave a conditional approval to install this�ystem a copy of which is <br /> attached. <br /> Respectfully <br /> Bob Volkenant <br /> Volkenant Inc. <br /> Copy: City of Orono <br />
