� . <br /> SITE EVALUATION REPORT <br /> For Dr. Hamad Sajjadi ' <br /> Sewage Treatment System <br /> GENERAL INFORMATION <br /> This design is for a Type 1, 4 bedroom home and in accordance with the Minnesota Pollution <br /> Control Agency.Standards and local ordinances. <br /> A seasonally high water table was evidenced at 29 inches of depth in Soil Borings 1, 2 & 3. The <br /> slope is about 8%. <br /> The soils at a depth of 12 in Test Holes 1, 2 and 3 have a percolation rate of 10 minutes per <br /> inch. All neighboring wells are located more than 100' away from the proposed treatment area. <br /> NOTES: <br /> Keep all heavy equipment off the proposed treatment area before and after construction <br /> as much as possible. The treatment area should be marked off before construction. <br /> With proper installation and maintenance this system should have no problem in treating <br /> septic effluent effectively. <br /> It is recommended that the septic tanks be pumped every 2 years. <br /> MOUND SYSTEM: <br /> Flow: 4 bedroom = 150 gallon/day/bedroom 150 x 4 = 600 gallons per day. <br /> 600 GPD x 0.83 = 500 square feet. <br /> 10—foot wide rock bed 50 feet long = 500 square feet <br /> CONSTRUCTION EQUIPNIENT: <br /> A rubber—tired tractor may be used for plowing or disking to prepare the soil surface but in no <br /> case shall a rubber—tired tractor be used after the surface preparation is completed. A crawler <br /> or tract—t}�pe tractor shall be used for mound construction. <br /> SOIL SURFACE PREPARATION: <br /> The discharge pipe from the pump to the mound area shall be installed prior to soil surface <br /> preparation. The trench escavated to install the discharge pipe shall be carefully backfilled and <br /> compacted to prevent seepage of effluent. <br /> PAGE 2 � � � <br />
